  Bridge decks have support through piers which are prone to damage because of vehicle movement and heat expansion. The main function of bridge bearings is - to offer a strong connection for controlling interactions of movements and loading between the structural parts (normally between the substructures and superstructures). Bride bearings give a uniform transfer of loads from the beams to the substructures. Both bridge bearings and expansion joints play chief roles in bridge construction.   What are bridge bearings and their function?   Bridge bearings carry movement/loads in both horizontal and vertical directions from the superstructure of brides. They help in conveying the loads to abutments and bridge piers. Loads can be dead load or live load in vertical direction/earthquake loads or wind load in horizontal directions. Bridge bearings and expansion joints are an important component of any bridge providing a resting surface. The main purpose of using such...

Valves are devices that control or direct and regulate the flow of fluids such as liquids, gases, slurries, fluidized solids etc by partially obstructing or closing several passageways. One of the vital and most common valves that are used in varied industries is - Gate valve. There are different types of gate valves used for different applications. One of them is Sewage gate valves . These valves are majorly used for wastewater. What are gate valves? Gate valves are known as sluice valves. They open by lifting the rectangular or round gate/ wedge. from the fluid's path. The main feature of gate valves is the sealing surface between the seats and the gates which are planar. This makes gate valves ideal to be used when minimum restriction and straight-line fluid flow are required. Gate valves are specially designed for serving as isolation valves. Gate valves help in controlling the fluid flow through pipes. These valves are installed to stop or start the water flow. They are ...

  What is an x-ray baggage scanner machine? The X-ray baggage scanner machines are vital for security systems. These machines rely on X-rays to watch through the surface of the luggage in order to get a precise image of the things inside. The security officers take help from an x-ray baggage scanning machine to calculate the density of the carrying object that gives them every bit of information they require to locate contrabands. Why are these machines so important?  The x-ray baggage scanner machines are important in finding out the hidden or smuggling contrabands along with dangerous weapons, explosives, illegal items, narcotics etc. When any baggage enters into the lead-lined curtains, items absorb a few x rays of energy. The main aim of security screenings with the help of these machines is to avoid harmful or dangerous goods from going into the aircraft or any other place. In the airports, every passenger needs to walk by the metal detectors and baggage is scanned with ...

The HDPE pipe fittings play a vital role in better water transmission and distribution systems. High-density polyethene pipe fittings are hard and light. These have smooth outer and inner surfaces. Use reliable HDPE fittings for your system.   Why are HDPE pipe fittings the most preferred ones?   The HDPE fittings for pipes are light in weight but durable and hard. Transportation of these fittings need less equipment and can be applied easily to every field condition even on the wet floor, ice, marshy areas etc. HDPE fittings for your pipes are mostly suitable for agriculture, irrigation, utilities, commercial, residential, industrial and many more purposes.   The HDPE pipe and its fittings are well sorted by strength. They undergo various tests and the tests show no such harmful effects on human beings. In the HDPE piping system, fittings are widely used as they offer efficient performance. The HDPE pipe fittings are economically great and easy to handle. The HDPE pipe ...

The whole process aims to create a safe environment devoid of wastes. Every single valve has its particular uses & conditions where it can operate under. For ensuring the right valve. You need to know all applications every valve is apt to handle. The main valve is the check valve. ...

In so many industries everyday compressors and bearing work in the assembly belts, cars, trains etc results in a constant flow of good production assembly or transport. For perfect operation and without stoppage, speciality lubricants help in boosting the performance of machines.                                                                                    What are speciality lubricants? The lubricant has always been playing a chief role in enhancing the performance of machines. In order to achieve good performance, speciality lubricants can be used. It also works even in the lowest temperatures as well as the highest temperature. Things can run much smoother with accurate lubricating oil. The speciality lubricant oils have amazing wetting and penetration capability to prote...

The gate valve is a valve that opens by raising the barrier out of the fluid path. The gate valve needs little space along the pipe axis. It restricts the fluid flow when the gate gets fully opened. More than the flow regulation, the gate valves are majorly used for shutting off the liquid flow. While it is completely opened, the normal gate valve gets no obstruction in its flow path and it results in low flow resistance. Mostly the gate valves are used with large pipe diameters (2" to the largest pipelines) because these are less complicated to build than any other valves in big sizes. You can reach out to the best firefighting gate valve in UAE to enhance your fire safety system. Gate valves have two categories. They are 1)Gate Valve Internal Structure:2) Gate Valve Stem Stent:   Some of the benefits of using Gate valves are:   a) The fixed and integral wedge nut of the gate valve prevents vibration. b) The wedge core is constructed of ductile iron and completely ...

A manhole cover is a detachable plate creating the lid on the top of the opening of the manhole. These are designed in a way to prevent anyone from falling in. If we go back to the Roman era, the sewer grates were built of lime sandstone. Now in this modern era, it has changed. While working on the manholes, you must know there is a distinction between the manhole covers. Not every manhole cover is built equal. There are various types of covers and everyone has their place to work for. If you are required to decide on purchasing manhole covers then you will need to weigh where you want to install them. Be clear about what the manhole cover in the place has to deal with yearly. Have a glance at the guidelines for buying the finest manhole covers: a) The capacity The first and foremost thing to ponder upon while choosing manhole covers is - Capacity. The capacity means how much load can continuously cross or pass over the manhole cover. Suppose we take an example of - "C"...
