In addition to using steel pipes as raw materials to produce eccentric reducing pipes, some specifications of reducing pipes can also be produced using stamping forming technology using steel plates. The shape of the stamping die used for stretching refers to the design of the inner surface size of the reducing pipe, and the steel plate after cutti1
Pipe cap, also known as head, plug, cap, pipe cap, or blind, is a pipe fitting welded to the pipe end or installed on the external thread of the pipe end to cover the pipe. Used to close pipelines, with the same effect as pipe plugs. The form of blind plates is similar, except that blind plates can be dismantled for sealing, while welded pipe caps 1
Bend pipes are bent using a complete set of bending molds, which are divided into two processes: cold bending and hot pushing. Regardless of the type of machine equipment and pipeline, most of them use bent pipes, mainly for oil, gas, infusion, and other purposes. Classification: According to the production method, it can be divided into pushing, p1
Gate valve refers to a valve whose opening and closing body (valve plate) is driven by the valve stem to lift the sealing surface of the valve seat, which can connect or cut off the passage of fluid. When the valve is partially opened, eddy currents are generated on the back of the gate, which can easily cause erosion and vibration of the gate, and1
Stainless steel elbows need to be protected according to certain process measures during use and production, to protect the rationality and quality of castings. Production and processing should be carried out according to certain process techniques to protect the quality of stainless steel elbows. The stainless steel elbow is protected by a long no1
D41W ventilation butterfly valve/D341W worm gear ventilation butterfly valve/D641W pneumatic ventilation butterfly valve/D941W electric ventilation butterfly valve is made of the same material as the valve body and processed into a sealing ring. Its applicable temperature depends on the material selection of the valve body, and the nominal pressure1
There are two design forms for Q11 forged steel ball valves. One is a two-piece structure, with threaded connections in the middle and sealed with PTFE gaskets; Another type is a three piece structure, with bolts in the middle. Depending on the selected valve seat and gasket/packing material, it can adapt to different working temperatures and media1
