Welded steel pipes are cylindrical products crafted from flat sheets, known as "blanks," which are shaped, bent, and readied for the welding process. The manufacturing of welded steel pipes is characterized by its straightforward production process, resulting in high efficiency, a wide range of available specifications, and the utilization of minimal equipment.
Welded steel pipes come in various types, each designed for specific applications based on their properties, dimensions, and intended use. Here are different types of welded steel pipes categorized by their common applications.
- GB/T3091-1993 (Galvanized Welded Steel Pipe for Low-Pressure Fluid Conveyance)
Primarily employed for the transfer of water, gas, air, oil, heating hot water, steam, and other generally low-pressure fluids for various applications. It features Q235A-grade steel as its representative material.
- GB/T3092-1993 (Galvanized Welded Steel Pipe for Low-Pressure Fluid Conveyance)
Mainly utilized for conveying water, gas, air, oil, heating hot water, steam, and other generally low-pressure fluids for diverse purposes. It is characterized by the use of Q235A-grade steel.
- GB/T14291-1992 (Welded Steel Pipe for Mining Fluid Conveyance)
Predominantly employed for straight-seam welded steel pipes used in mine pressure, drainage, and shaft gas discharge. The representative material for this application is Q235A, Grade B steel.
- GB/T14980-1994 (Large-Diameter Electric Welded Steel Pipe for Low-Pressure Fluid Conveyance)
Its primary purpose is the transportation of low-pressure fluids like water, sewage, gas, air, and heating steam for various applications. The representative material used is Q235A-grade steel.
- GB/T12770-1991 (Stainless Steel Welded Steel Pipe for Mechanical Structures)
Mainly utilized in machinery, automobiles, bicycles, furniture, hotel and restaurant decorations, and other mechanical and structural components. The representative materials include 0Cr13, 1Cr17, 00Cr19Ni11, 1Cr18Ni9, 0Cr18Ni11Nb, and more.
- GB/T12771-1991 (Stainless Steel Welded Steel Pipe for Fluid Conveyance)
Primarily employed for transporting low-pressure corrosive media. Representative materials used for this purpose encompass 0Cr13, 0Cr19Ni9, 00Cr19Ni11, 00Cr17, 0Cr18Ni11Nb, 0017Cr17Ni14Mo2, and so on.
