Bolting for Flanges
Flanges are an important component to connect pipes, valves, pumps and other equipment to form a piping system. Flanges allow for easy operations incase of cleaning, inspection or modification. Flanges are usually welded or screwed. With the proper combination of bolting tools and correct nut-bolts or stud-bolts as defined in the specifications; Flanged joints make a sealed connection between two flanges with a gasket which ensures leakage free movement. To obtain a leak-free flange connection, a proper gasket installation is needed, the bolts must be assigned on the correct bolt tension, and the total bolt strength must be evenly divided over the whole flange face. With bolt torquing - the appropriate bolt tensioning is realized by applying the preload through turning the fastener's nut at a determined torque value. To get the best out of the bolt’s elastic properties a bolt needs to be accurately tightened. The characteristic of the bolt enables it to work like a spring to wo...
