In the daily use of valves will often encounter a variety of failures, valve body and cover leakage is one of the many failures, what is the cause of this phenomenon? What other failures need to be noted?

The material detailed information for the butt welding pipe fittings

The tolerance for butt welding pipe fittings ASME B16.9

The butt welding tee has three nozzles, namely one inlet and two outlets; or two inlets and one outlet. The main function of butt welding tee is to change the direction of the fluid. From the shape, it can be divided into three types: T-shaped tee, Y-shaped tee and lateral tee. From the pipe diameter size, butt welding tee is divided into equal diameter tee and reducing tee., the connecting ends of equal-diameter tees are all the same size; the main pipe connecting size of the reducing tees is the same, while the branch pipe connecting size is smaller than that of the main pipe size.

Selection factors of raw materials for stainless steel welded pipe fittings

The forged pipe fittings are high pressure pipe fittings, which are molded by round steel or ingot to forge blank, and then machined by lathe.
