Stainless Steel Pipe Fitting According to the different ways
Three links for the pipe, pipe fittings. Also known as pipe fittings three links or three pipe fittings, tee joints, used in the main pipeline to branch pipe.
The diameter of the three-way pipe is the same size, and the size of the branch pipe is smaller than the size of the pipe in charge of the main pipe.
The tee is a pipe for the pipe branch. For the use of seamless pipe manufacturing in terms of three links, the current commonly used in the process of hydraulic bulging and hot forming two.
The four ends of the same diameter and diameter of the same size, and the size of the branch pipe is smaller than the size of the main pipe.
Welding Stone is a pipe for the pipe branch of a pipe. For the use of seamless pipe manufacturing in terms of four, the current commonly used in the process of hydraulic bulging and hot forming two.
Stainless steel pipe fittings according to the different ways, classification is not the same.
Sort by production method:
(1), seamless tube - cold drawn tube, extruded tube, cold rolled tube.
(2), welded pipe:
(A) Classification by process - Gas shielded pipe, arc welded pipe, resistance welded pipe (high frequency, low frequency).
(B) by weld seam - straight seam welded pipe, spiral welded pipe.
According to the cross-section shape classification: (1) circular steel pipe; (2) rectangular tube.
Classification by wall thickness - thin-walled steel pipe, thick-walled steel pipe
(2) industrial pipe: steel pipe for industrial piping, general pipe with pipe (drinking water pipe), pipe, pipe, pipe, pipe, pipe, pipe, , Mechanical structure / fluid delivery pipe, boiler heat exchange tubes, food hygiene pipes. Generally used in various fields such as: petrochemical, paper, nuclear, food, beverage, pharmaceutical and other industries on the fluid medium requires a higher pipeline.
Seamless elbow: Elbow is a pipe used for pipe turning. In the pipe system used in all the pipe, the largest proportion, about 80%. Typically, different forming processes are selected for elbows of different materials or wall thicknesses. Manufacturers commonly used seamless elbow forming process has hot push, stamping, extrusion and so on.
Hot push forming
The heat-pushing elbow forming process uses a special elbow pushing machine, a core mold and a heating device so that the blank placed on the mold is moved forward with the pushing of the push machine and is heated, expanded and bent during the movement the process of. The deformation of the thermocouple is characterized by the fact that the diameter of the tube is determined according to the law of the volume before and after the plastic deformation of the metal material. The diameter of the tube is less than the diameter of the elbow, and the deformation of the blank is controlled by the core mold, Of the metal flow, to compensate for the expansion of the other parts of the thinning, resulting in uniform wall thickness of the elbow.
