Right time for the new ideas in building

Building uniqueness, logically it is laid in ideas of unique personalities. The power of architecture should not be underestimated nowadays. The time comes, when architecture not only creates new building, but it also represents and put some piece of soul, heart and sense in them.

However, the problem is that over the last fifty years, the construction and design industry become complicated and controversial. Under normal condition, it happens because of new tendencies and styles in this sphere. In pursuing something extraordinary, architectures forget about order’s preferences and tastes and this problem brings about trials in the court. A lot of architectures are coward to face liability and stepped back to marginalized position. They announced this position as the right place of architecture.

The right outcome from this difficult situation is creation and performance. If they start authorizing processes anew instead of authorizing the objects, everything will work out well in the long run. Once they have done this, there is every likelihood that possibility of coming back of social engineering into architecture will be successful.

Today, the most famous and innovative building services company in UK is Piggott & Whitfield. It is not afraid of making mistakes because their projects are so professional, up-to-date, catching and qualitative that no complains arise. In their list you could find such well-known building like Manchester Cancer Center, The Whitehall, Tate Britain, Old Place Yard, Hannover Square, Halborn Police Station and The Walton Center. As for services, they provide design, construction, installation, mechanical and electrical services etc.

Only a one decade ago, another building company dared to chance the cause of history once and for all. They built the theater that remakes itself. It is named Dallas Theater, which had notoriety because nobody would expect something worthy of this place. However, their idea seems to be truly crazy and impossible to implement at first glance, but the things happen virtually vice versa. Architectures created theater machine that have ability to move between series of design. By pushing the particular button and helping hands of few stage workers, they could change decoration in a short amount of time. Moreover, there is a potential that allow spectator and actors to move directly from outside into the interior of the auditorium. It is so-called Wagnerian entrance. Could you imagine the performance in which the first act takes place in trust, an intermission Greek, the second act in arena and in the end you can leave the building through the lobby. In such way, not only actors are performing, but also architecture. It reminds one continuous system that let magic begins.

To sum up, previous mentioned examples prove that building services definitely could do something. Successful collaboration between client and professional building group without a doubt could create new tendencies and breathtaking masterpieces in architecture. Even if you never expect that you could create great and prominent objects, do not dwell on these negative thoughts, look on the bright side and believe in power of your brilliant idea and possibilities that make it true.

Gantry Hoist Design In A Nutshell

Gantry cranes represent the constructions with the horizontal bridge based on two pillars, moving on land rail tracks. Both bearings have a tight junction with the bridge, while one of the pillars of the bridge can be held by hinges.

Those cranes whose superstructure rests on one side of the support leg and the other one mounted directly on the truck running, are called semi-cranes. Rail tracks in this case are located at different levels, one on land and the other one on a special trestle or columns of the building.

There are two basic schemes used for bridge design – beam and girder. Single-girder bridges with triangular and quadrangular cross section with sled monorail are the most widespread. This construction has proved its cost-efficiency, and the large industry players, like Granada Material Handling, focusing on gantry hoist and overhead crane manufacturing, concentrate plenty of their effort on single-girder bridges.

The span girder and double-girder bridges in their design are usually similar to the beam overhead cranes. Rigid and flexible support of gantry cranes is carried out through individual racks which design depends on the type of support. Flexible support pillar has a single element or a farm, rotate in a direction perpendicular to the bridge. (more…)

Modern Cleaning Methods – The Ultrasonic Approach

Ultrasonic cleaning is a purification method based on the use of non-linear effects arising in the liquid subjected to ultrasonic vibration. Among these effects, perhaps, the most significant one is cavitation; however, there is also a range of ‘additional’ effects to point out, such as acoustic flow, sound pressure and acoustocapillary effect.

Cavitation is the process of formation of cavities and bubbles in an ultrasonic field during the phase of stretching, available in varying sound pressure. During the compression phase, these cavities and bubbles collapse. Cavitation accelerates the course of a number of physical and chemical processes. The reason for the exceptional efficiency of cavitation is that the bubbles starts from the slamming of the surface being cleaned. Cavitation is accompanied by the appearance of a very high instantaneous hydrostatic pressure that comes off sticking to the surface being cleaned dirt particles.

Ultrasonic cleaning in the laboratory

Cavitation can be heard as hissing noise generated in the liquid at a certain value of the intensity of the ultrasonic field. The Introduction of ultrasonic oscillations in the washing solutions can not only speed up the cleaning process, but also to obtain a higher degree of surface cleanliness. In most cases, attempts to eliminate flammable and toxic organic solvents and aqueous solutions used exclusively technical detergents. This undoubtedly leads to improved working conditions, higher production standards, and also allows to partially solve the issues of environmental safety.

The ultrasound is used for removal of contaminants arising during production of parts and products, as well as during their operation. Ultrasonic cleaning is particularly useful in the preparation of ultrasonic cleaning surfaces prior to coating and cleaning complex cavities and channels in the products. Much depends on the equipment – thus, the innovative ultrasonic cleaner devices by Hilsonic, a seasoned UK-based manufacturer with years of experience, will demonstrate way better performance in an average cleaning case.

Ultrasound is widely used for cleaning wire, metal strip, nozzles, cable, and others. The specific application of the technology of ultrasonic cleaning includes cleaning powders, radioactively contaminated surfaces, the regeneration of ceramic filters, etc. (more…)

How It Works: Steel Blind Flanges

Blind flanges are installed at the pipelines endings and differ from conventional steel flanges with the absence of a central hole. Steel flanges are designed to overlap the endings of the medium pipes (or tube plates, all the piping equipment is typically assembled at a particular facility, if medium-large scale businesses are considered, e.g. Birmingham-based AlexanderComley facilities) and typically mounted by means of bolts or studs.

Blind flange part of the pipeline is designed to lock the end portions of the pipeline. A true to type blind flange is round in shape with an annular bearing surface and holes in it for the bolts to attach the pipe fittings.

The purpose of blind flanges is blocking any branches of the pipeline without the need of their further usage. This is their essential difference from the flange, the function of which is to connect the sections of the pipeline.

Blind flange steel

Depending on the required performance and quality of the final result, steel flanged caps are constructed basing on a variety of technologies: e.g. hot stamping or gas scraping from sheets of top grade steel or metal.

  • The method of hot stamping. This method is technologically, high production speed, ease of manufacture. The disadvantages of this method are the high energy consumption and high operational expenses, resulting in an increased cost of the product.
  • Gas or plasma cutting of sheet metal or long products. The advantages of this method are evident: no cracks, voids in the metal, improved mechanical properties and a better weldability. Disadvantages of this method: high metal consumption and still high end-cost of the product.

The use of these methods is explained by the highest-quality product obtained as a result with no cracks and voids in the base. Through the use of modern technology blind steel flanges are characterized by impeccable strength and long years of service, as well as improved mechanical properties, contributing to easier installation and maintenance.

Flanged plugs have a wide range of applications: they are utilised in a multitude of industries, such as gas, oil, chemical, as well as in building water, gas and oil pipelines. Steel flanges are manufactured in accordance with state standards and specifications for piping and components have a high degree of resistance to corrosion, corrosion activity and the impact of transported substances, enableing reliable use in different climatic conditions: both high (up to 650 degrees) and cold (-70 degrees centigrade) temperatures.

There is a wide variety of pipe stub types and modifications. Blind flanges vary in diameter from 32 to 1020 mm, they retain the performance characteristics at a temperature of from -70° C to + 600° C and pressure to 160 kg / cm 2.

Apart from producing flanges meeting the particular standards, a firm may take advantage of ordering a custom solution that meets the requirements of a particular construction. AlexanderComley is an exemplary centre providing a variety of both standard (ANSI/ASME, API, etc.) and custom-designed stainless steel flanges and butt weld fittings uk stand out from the crowd with extraordinary quality and impressive guarantee terms.

The Advantages Of Glass Reinforced Concrete In Roofing

Glass reinforced concrete represents an ideal material for all types of roofing. Being a lightweight and durable at the same time, installing a GRC roof is a relatively easy job; and moreover, glass reinforced concrete is exposed to polluting elements, even in the face of environmental pollution in large cities.

Externally GRC can play the role of traditional roofing materials such as slate, natural stone or clay tiles, but unlike direct competitors it is neither characterised by heaviness, nor by fragility. In addition, GRC provides a stunning opportunity to implement complex configuration projects, such as umbrella chimneys and eaves. Thus, it can help you solve the roofing problem in both residential and commercial buildings: GRC is nonflammable and boasts high toughness, that’s why it is oftentimes utilised in factories and production facilities.

For pitched roofs GRC can successfully mimic the natural slate-like appearance. To mount the roof one can use standard slating nails without pre-drilling holes, and due to the inherent strength of glass reinforced concrete, the probability of chopping during mounting is excluded.

Flat roofs can be made more attractive by using tiles with non-slip ribbed surface; it comes in a variety of colors achieved through the use of natural pigments or colored sand.

Corrugated roofing sheets made of glass reinforced concrete  that have no asbestos in its composition, show themselves as very flexible and non-friable materials. Unlike asbestos products, which are often prone to brittle fractures with disastrous consequences, GRC withstands much greater shock effortlessly. Making a choice in favor of GRC-based materials for roofing is always a wise decision from financial prospects: due to its unmatched strength, the material will inevitably pay for itself in the long run.

A New Word In VOC Removal Industry

The patent bank has recently been replenished with a new patent request. The invention relates to the field of chemistry, and in particular to devices designed for cleaning the ozone catalytic industrial gas emissions (yet the idea is implementable in odour control systems). The invention can be used in chemical, engineering and a range of other industries. The inventive device carries a catalytic reactor, with the catalyst and several layers with a free space therebetween, valves with nozzles supplying ozone-air mixture located in the free space between the catalyst beds, the regenerative heat exchangers arranged along the gas before and after the catalyst layers, and a switching device for changing the direction of feed gas to be purified by reversed.

The invention is related to voc removal area, in particular to a catalytic treatment of industrial gases from the impurity of organic substances. The invention aims at cleaning of gas streams effectively, for example, ventilation gases of huge flow rate and relatively low concentration of organic compounds. For purification of such gaseous emissions ozone-catalytic methods are developed which are effective in oxidizing the organic matter while forming harmless compounds, carbon dioxide and water.

In addition, the inventive device is intended for gas purification from impurities of organic compounds through ozone-catalytic process that can be adopted at chemical, engineering and heavy machinery production industries. The device boasts reasonable dimensions and relatively easy installation (thus, the construction needs no reinforcement or bund walls).

The device promises a reliable and efficient purifying of high velocity gas streams, including wet impurities from organic substances, in particular in the case of frequent and abrupt fluctuations of impurity concentrations of organic substances, which is particularly important in the purification of industrial waste gases.

Water Borehole Drilling: Frequently Asked Questions

Water borehole drilling is aimed to reach the aquifer at the depth of 30-200 and in accordance with the depth, well performance (up to 100 m3/hour) and the complexity of drilling. Artesian wells are characterized by larger diameter and greater depth, which in turn requires installing blocking mechanisms and cases. As a result, an extra complex of measures affects the total cost.

The drilling job is typically carried out within 2+ days, though the terms depend on the particular area in a great way. The fact should be underlined that the price for limestone drilling is higher, though such wells boast an increased lifespan: 50 years or more, since limestone plays the role of the filter, protecting the system from silting.

What is the diameter of the well?

The diameter for sand and limestone grounds varies from 127 to 324 mm, depending on the pump performance and the depth of the borehole. However, industrial wells may dictate way larger diameters.

What types of pipes are used in artesian well?

As a rule, the ones made of ferrous metal with threaded or welded connections are installed. Using galvanized pipes is prohibited, since it represents the hotbed of harmful zinc compounds.

Do I need plastic?

On the one hand, the market is oozing with advanced plastic materials, however, there is no fair and absolutely reasonable data on long term using. Therefore, geophysics has no answer to whether the material will keep on handling the regular load within 20 – 40 years, while the lifespan of ferrous metal components is known already: the material of 5mm in thickness is highly likely to serve at least 50 years (taking into account the average corrosion rate of 0.1 mm per year).

However, to meet the most sophisticated demands may include installing plastic pipes in the well: these components will hardly prevent the mechanism from corrosion, yet they will prolong the pump’s lifetime, cutting corroded particles from the walls of the steel columns). Sometimes, especially in difficult geological conditions, a plastic column inside a steel one may be useful, meaning that both types of pipes are used as an integral mechanism.

Country House Outdoor Lighting Functionality

When developing an outdoor lighting project, ensuring proper functionality is certainly the main objective to keep in mind. The key areas: the main gate and the main path leading to the house should be more illuminated than, for example, remote corners of the garden. Working areas as well as parking spaces should also be well lit, but this is where you can play with the intensity of the rays. Installing individual light sources for the main areas is normal practice: pendant lights, plastic, ceramic, glass, and particularly popular, forged metal ones, are perfect to spot lighting areas around the house. The classic exteriors can be complemented perfectly with victorian street lighting elements; as an option, consider more neutral heritage street lighting fixtures.

At some distance from the dwelling exterior designers oftentimes offer to install massive lights on poles of different heights. Drop in at Metcraft online store for the largest selection of classic lamps – the lineup covers the entire range of outdoor lighting fixtures. Moreover, with penetrating light beams you can visually enlarge the area of ​​the garden, or press for sparkling surface of a pond or swimming pool.

Small wall lights complement the composition of lights and poles, filling the gaps created by large light sources. Compact lighting installations look particularly good not only on the walls of the cottage, but also on the railings and other vertical surfaces of veranda or pergola.

Street lighting will surely help to form the complete, harmonious exterior, if you take advantage of installing triple A class units. However, make sure the fixtures are not adjusted to direct the rays on windows or recreation areas. Actually, this rule applies not only to the spotlights, but also to any other fixtures with powerful lamps.

Parking Ventilation Nuances Explained: Space Length

The average length of the car parking spaces is an absolutely vital parameter the parking ventilation designer pays attention to. The space is naturally determined by the overall size of the construction, as well as traffic management schemes and the number of cars, standing at a certain time in a queue to enter or exit the parking lot. According to the United Kingdom statistics, such movement duration typically equals from 60 to 600 seconds. On average, however, it can be assumed that these values ​​are in the range of 60 to 180 seconds. Thus the average duration of entering equals 40 seconds approximate, while it takes around 55 seconds for the vehicle to leave the carport. It should be borne in mind that the parameters of the engines of the cars in the garage and in normal traffic differ significantly.

Pollution stats

The entering vehicles enter the lot with the motor warmed up, reducing their speed to 5-8 km/h Therefore, their ‘contribution’ to the pollution of the environment is limited. However, the leaving cars, on the contrary, emit more exhaust gases due to their cold engines in low gear. It should be noted that the level of emissions is significantly higher in winter than in summer, since the engines are colder the winter; these numbers can be almost five times higher. Thus, e.g. U.S. Board of Industrial Hygiene recommends the maximum permissible value of the concentration of CO at the level of 29 mg/m3 for a period of not more than 8 hours. In turn, the Environmental Protection Agency (EPA) states that for territories at sea level or close to it, the concentration of 40 mg/m3 of not more than an hour is not harmful to health. Conversely, more stringent standards are set for the altitudes of 1,000 meters and above.  Thus, erecting a fully-compliant parking lot demands installing a car park ventilation system adjusted thoroughly to the parameters mentioned above.

General Instructions For Applying Polyshield

To improve adhesion significantly, Polyshield must be applied to clean, dry and solid surface that contains no loose particles or other 3rd party substances. Laying undercoat may be needed to prepare the ground properly. To guarantee proper results, consulting a technical specialist for specific recommendations on the choice of undercoating and substrate preparation procedure may be required.

Polyshield can be sprayed in a wide range of ambient temperatures and types of surfaces; thus, it may be used in residential structures roof waterproofing, mining facilities roof coating and etc. The restrictions are predominantly applied to equipment and its deposition parameters to ensure a certain pressure and temperature. The material is recommended to be sprayed in all directions (north-south/east-west) to provide uniform thickness.

Polyshield applying equipment

Polyshield is sprayed via two-component nebulizers, the appliances with accurate dosing of A and B components in the mixing ratio of 1:1 that provide minimum dynamic pressure of 2000 psi (13.9 mpa) with components heating to 175°F (79°C). Mentioned further are the systems utilised by the professional Polyshield coating firms: REACTOR E-XP1, REACTOR E-XP2, REACTOR H-XP2, REACTOR E-XP3 by GRACO company with working pressure of 17.2 to 24.0 MPa, capacities from 3.8 to 9.5 l/min and radiator/engine capacity from 10.2 to 20.4 kW. A true to type installation represents a complex comprised of a dispenser compressor, feed pump, high pressure spray gun and a recirculation system .

The components are recommended to be heated up to 160-170°F (71-76°C) approximately. The temperature of the hoses should not exceed 160-170°F (71-76 ° C), while the hoses thermometer, mounted near the gun, should reflect the minimum temperature of 145-155°F (63-68°C).
