Standard of large diameter Arc Welding Steel Pipe

Gulp of straight seam Arc Welding Steel Pipe standards: also called welded steel pipe, is to use steel plate or steel strip after bending forming, electric model to 0317. 6012755 standard, and then through the high frequency welding, submerged arc welding. Divided into the form of the weld seam welded pipe and spiral welded pipe. According to the application is divided into general welded pipe, galvanized welded pipe, oxygen blowing metric welded pipe, welded pipe, wire casing, roller tube, deep well pump pipe, auto tube, transformer, electric welding thin wall pipe, welded pipe and spiral welded pipe.

General welded pipe: general welding work for low pressure liquid. Execution standard GB/T0317 number 6012889. Use Q195A, Q215A, Q235A steel manufacturing. Also can be used to other mild steel welding manufacturing. Steel pipe for pressure, bending, flattening and so on experiment, the surface quality is a certain request, usually the delivery length for 4 to 10 m, often required scale (or foot) delivery of the goods. Of the specifications of the welded pipe in nominal diameter (mm or inches) nominal diameter is different from the actual, welded pipe wall thickness by the regulation with ordinary steel pipe and thickening steel pipe, steel pipe and the form of the pipe end points with thread and does not take two, table 6 to 17 for welded steel pipe size.

Mouth straight seam welded pipe is a general term, ways to use steel strip production, in the high frequency welding equipment straight seam welded pipe are called straight seam welded pipe. (due to spot welding with steel pipe into a straight line and name). After which, according to various USES and different production process. (can be roughly divided into the scaffold tube, fluid pipe, wire casing, stent tube, guardrail tube etc.)

And low pressure fluid welded pipe is a kind of straight seam welded pipe, generally water, gas transmission, is more than general welded pipe after welding ends to a water pressure test, so low pressure fluid tube a little higher than ordinary straight seam welded pipe prices generally
