Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip after crimping and welding, generally 6 meters. Welded steel pipe production process is simple, high production efficiency, variety specifications, less investment in equipment, but the general strength is lower than seamless steel pipe.Straight seam welded pipe, steel pipe made of hot or cold rolled steel plate or steel strip coil welding, straight seam welded pipe on welding equipment are called straight seam welded pipe.

For liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas.
For structure: for piling pipe, as a bridge; Pipe for wharf, road, building structure, etc.
According to different materials and uses, it can be divided into welding steel pipe for mining fluid transportation, galvanized welding steel pipe for low pressure fluid transportation, electric welding steel pipe for belt conveyor roller, etc.

Generally welded pipe for water, gas, air, oil and heating steam and other general low pressure fluid transmission.
Ordinary carbon steel wire bushing (GB3640-88) is a steel pipe used to protect wires in industrial and civil buildings,
installation machines and equipment and other electrical installation projects.
