Welded steel pipes

Description

Welded steel pipes, also known as welded tubes, are manufactured by shaping and welding steel plates or strips. This process results in a cost-effective and efficient production method, allowing for a diverse range of pipe types. While welded steel pipes are generally more economical and easier to produce than seamless pipes, they typically have lower overall strength.
Depending on the welding process, welded steel pipes are categorized into furnace-welded pipes, electric resistance welded (ERW) pipes, and automatic arc-welded pipes. Based on their seam structure, they are classified as straight seam welded pipes or spiral welded pipes. In terms of shape, welded pipes can be round or specially designed, such as square or flat pipes. Additionally, they are classified by application, including general welded pipes, galvanized pipes, oxygen-blown pipes, wire conduit pipes, metric welded pipes, roller pipes, deep well pump pipes, automotive pipes, transformer pipes, thin-wall welded pipes, and spiral welded pipes.
The versatility of welded steel pipes makes them indispensable in various industries. They are widely used in the construction of boilers, automobiles, ships, lightweight structural elements like doors and windows, furniture manufacturing, agricultural machinery, scaffolding, electrical wiring systems, high-rise storage racks, and containers. Due to the variety of welding techniques, different manufacturing methods are employed to meet specific industry requirements.
