Product Description

ASTM A53 GR.B carbon welded steel pipe, also known as welded pipe, is widely used in water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction. For liquid transportation: water supply, drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structure: for piling pipe, for bridge; for wharf, road, building structure, etc. Welded steel pipe is a steel pipe made of steel plate or strip steel by crimping and welding, and the length is generally 6 meters. Welded steel pipes have simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but the general strength is lower than that of seamless steel pipes.
Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of the weld. Classification by production method: process classification - arc welded pipe, electric resistance welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.
Smaller diameter welded pipes use straight seam welding, and large diameter welded pipes are mostly spiral welded; according to the shape of the end of the steel pipe, they are divided into circular welded pipes and special-shaped (square, rectangular, etc.) welded pipes; according to different materials and uses, they are divided into mining fluids Conveying welded steel pipe, galvanized welded steel pipe for low-pressure fluid transportation, electric-welded steel pipe for belt conveyor rollers, etc. According to the classification, 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 welding thin-walled pipe, electric welding special-shaped pipe, scaffolding pipe and spiral welded pipes.
