Contractors choose scaffolding systems depending on the type of work they have at hand – this article explores the options on offer. Steel Scaffolding Steel scaffolding is made up of steel tubes which makes it quite a robust scaffolding system. Such a scaffold can be used for work on a building’s exterior. It can reach great heights without affecting the safety of the scaffold, and it can also withstand harsh weather conditions. It can carry heavy loads therefore increasing efficiency and saving time. Suspended Scaffolding As the name suggests, suspended scaffolding refers to a scaffold system that hangs from the ceiling of a building. These scaffolds are normally used for interior projects, such as painting, electrical work, repairs, etc. They can reach great heights and complete the work by employing a quick and efficient scaffold that is easily adjusted according to the situation.

An essential element in the design of water and wastewater pumping systems is the proper selection of pump discharge   check valves , which are designed to automatically open to allow positive flow and automatically return to the closed position to prevent pump backflow. Not operating. Another often overlooked feature is the valve's ability to minimize energy consumption.   But just as important, valves should protect pumping systems and piping from pressure fluctuations caused by sudden closures. Every pump station designer has witnessed check valve slamming, which is caused by the sudden stop of backflow through the closed check valve. To prevent slamming, automatic check valves must be closed very quickly or slowly using an oil buffer device. Check valves are generally classified into three categories. Ductile iron Rubber Disc Check Valve Even with knowledge of all the various categories and  types of check valves , it is still difficult to reasonably decide which type of check
