What is the difference between
straight seam steel pipe and other welded pipes
straight seam steel pipe:
straight seam steel pipe are made of steel plates or strips that are bent and then welded. According to the weld form, it is divided into
straight seam steel pipe and spiral welded pipe. According to the purpose, it is divided into general welded pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welded thin-walled pipe, electric welded special-shaped pipe and spiral welded pipe. Among them, according to different purposes, there are different post-production processes.
Other welded pipes:Welded steel pipe
Also called welded pipe, it is cut into narrow steel strips from steel strips, and then wrapped into tubes by cold working with molds. A special welder then welds a pipe seam. The outer weld seams are polished brightly. The internal burrs of ordinary welded pipes are not punched. Only precision welded pipes have internal burrs.
Anti-corrosion points: Welded steel pipe refers to a steel pipe with seams on the surface that is welded after bending and deforming a steel strip or steel plate into a round, square, etc. shape. According to different welding methods, it can be divided into arc welded pipes, high frequency or low frequency resistance welded pipes, gas welded pipes, furnace welded pipes, Bondi pipes, etc. According to the shape of the weld, it can be divided into straight seam welded pipe and spiral welded pipe. Electric welded steel pipes are used in oil drilling, machinery and manufacturing industries, etc. Furnace welded pipes can be used as water gas pipes, etc., large-diameter straight seam welded pipes are used for high-pressure oil and gas transportation, etc.; spiral welded pipes are used for oil and gas transportation, pipe piles, bridge piers, etc. Welded steel pipes have lower cost and higher production efficiency than seamless steel pipes.

General welded pipe
Generally, welded pipes are used to transport low-pressure fluids. Made of Q195A, Q215A, Q235A steel. It can also be manufactured from other mild steels that are easy to weld. Steel pipes are subject to water pressure, bending, flattening and other tests, and have certain requirements for surface quality. Usually, the delivery length is 4-10m, and it is often required to deliver in fixed length (or double length). The specification of the welded pipe is indicated by the nominal diameter (millimeter or inch). The nominal diameter is different from the actual one. The welded pipe has two types of ordinary steel pipe and thickened steel pipe according to the specified wall thickness. 6-17 is the size of welded steel pipe.
The difference between
straight seam steel pipe and other welded pipe
There is no need for electric welding machines and high-frequency resistance
straight seam steel pipe with wires, and there is no need to make cross-ground wires, no need to paint, and the complicated construction procedures such as traditional fusion welding and wire sleeves are omitted. Just connect the straight pipe joint to the pipe and the threaded pipe joint to the theoretical weight of the round steel pipe and the junction box. Just set it. The pipe bender can be used to bend the corresponding arc on site at the corner of the pipeline.
