The welding steel pipe is also known as the welded pipe. It is a steel pipe made of steel plates or steel with steel. Generally, it is 6 meters. Welding steel pipe production technology is simple, production effectiveness, many varieties, small equipment, but general strength is lower than seamless steel pipes.
1. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes in the form of welded steel pipes. Moreover, relatively speaking, small -caliber welded pipes use straight seam welding, and large -caliber welded pipes are mostly spiral welded
2. Classification according to the production method: process classification-arc welded pipe, resistor welding pipe, (high frequency, low-frequency) gas welding pipe, furnace welding pipe.
3. According to the shape of the steel pipe end, it is divided into circular welded pipes and heterogeneous (square, rectangular type, etc.) welded pipes; different materials and uses are divided into mineral fluid transport welding steel pipes, galvanized welding steel pipes for low -voltage fluid conveyor Rolling roller welding steel pipes.
4. It is divided into general welded pipes, galvanized welded pipes, oxygen -blowing welded pipes, wire sleeves, public welding pipes, roller pumps, deep well pumps, automotive pipes, transformer pipes, welding thin wall pipes, welding leiest pipes, scaffolding scaffolding, scaffolding Tube and spiral tube.
