Typically welded pipes are used to deliver low pressure fluids. Made of Q195A, Q215A, Q235A steel. It can also be made of other mild steels that are easy to weld. The steel pipe should be subjected to hydraulic pressure, bending, flattening and other tests. It has certain requirements on the surface quality, usually the delivery length is 4-10m, and often requires length (or multiple feet) delivery. The specification of the welded pipe is expressed by the nominal diameter (mm or inch). The nominal diameter is different from the actual one. The welded pipe has two kinds of common steel pipe and thickened steel pipe according to the specified wall thickness. The steel pipe is divided into two types according to the pipe end, with or without threads.


There is no need for electric welding machines and high-frequency-resistance straight seam welded pipes, and no cross-grounding lines are required. No painting is required, eliminating the need for complicated construction processes such as traditional fusion welding and bushings. Simply connect the straight pipe joint to the pipe, the threaded pipe joint to the theoretical weight of the round steel pipe and the junction box. After positioning, use a special tool to tighten (screw) the screw, and use the lock nut to lock the high frequency resistance joint of the terminal box.
