Welded steel pipe Classification by use

Welded steel pipe

Welded steel pipe refers to the steel pipe with steel strip or steel plate bending deformation into a circular square shape after welding the surface of the steel pipe with seam welding steel pipe using steel plate or strip steel.

Classification according to application: general welded steel pipe, galvanized welded steel pipe, oxygen blowing welded pipe, wire casing, metric welded steel pipe, roller pipe, deep well pump pipe, automotive pipe, transformer tube, welded thin-walled pipe, welded abnormal pipe and spiral welded pipe

    General welded pipe

general Welded steel pipe  is used to transport low pressure fluid. It is made of q195a, q215a, Q235A steel. It can also be made with other soft steel which is easily welded. The steel pipe should carry out the test of water pressure, bending, flattening and so on. It has a certain requirement on the surface quality, usually the delivery length is 4-10m. The nominal diameter of millimeter or inch is different from that of the actual. According to the specified wall thickness, the welded pipe has two kinds of ordinary steel pipe and thick steel pipe, and the pipe is divided into two kinds of thread and no thread according

Galvanized Welded pipe 

Galvanized steel pipe In order to improve the corrosion resistance of steel pipe, galvanized steel pipe is used. Galvanized steel pipe is divided into hot galvanizing and galvanizing. The galvanizing layer is thick and the cost of zinc plating is low.

 Roller tube

Roller tube For belt conveyor roller welding steel pipe, generally made of Q215OQ235AZB and 20 steel, diameter 63.5-219.0mm. For tube bending, the end face should be perpendicular to the center line, and the ellipticity is required. Water pressure and flattening tests are generally carried out.、

 Welded thin-walled pipe

Welded thin-Welded steel pipe  Mainly used to make furniture, toys, lamps, etc. The current stainless steel strip made of thin-walled tubes are widely used, high-grade furniture, decoration, fence and so on.

 Spiral Welded pipe 

Spiral Welded steel pipe  The steel strip of low carbon structure or low alloy structure steel is rolled into tube blank at a certain spiral angle (called forming angle), and then welded together. It can be used to produce large diameter steel pipe with narrow strip steel. Spiral welded pipe is mainly used for oil and natural gas pipeline, its specification is expressed by external diameter * wall thickness. The spiral welded pipe has one side welding and two side welding, the welded pipe should ensure the water pressure test, and the tensile strength and cold bending property of the weld should conform to the regulations.
