Classification and use of welded pipes

Welded steel pipe, abbreviated as welded steel pipe, is basically made of steel plate or material that has been rolled and formed into welded steel pipes. The production process of welded steel pipes is intuitive, with high production efficiency, multiple varieties and specifications, and limited equipment resources, but usually lower strength than seamless steel pipes. Since the 1930s, with the rapid development of high-quality soft and hard production and the gradual progress of stamping and inspection technology, the quality of welds has gradually improved, and the variety and specifications of welded steel pipes have increased rapidly, replacing seamless steel pipes in more and more fields. Welding is divided into straight seam welded pipes and spiral welded pipes in the form of welds.

1. Classification of welded pipes

Classification method for welded pipes based on their usage: They are further divided into ordinary welded pipes, galvanized welded pipes, oxygen blown welded pipes, wire sleeves, metric welded pipes, roller pipes, deep well pump pipes, automotive pipes, transformer pipes, welded thin-walled pipes, welded special shaped pipes, and spiral welded pipes according to their usage.

2. Application scope of welded pipes

Construction field: In construction engineering, welded pipes are mainly used for indoor and outdoor water, heating, and gas pipelines, as well as wire pipelines and scaffolding for supporting construction.

Water conservancy field: Welded pipes are used in water conservancy engineering to transport water sources and water drainage, such as urban water supply, drainage pipelines, fisheries and aquaculture.

Petroleum field: Welded pipes have a wide range of applications in the petroleum industry, including oil suction equipment, oil pipelines, refining devices, and oilfield pipelines.

Chemical industry: Welded pipes are widely used in the chemical industry, such as transporting oil and gas, chemical raw materials, etc., with a wide range of applications.
