Welded steel pipe is a type of steel pipe that is formed by welding steel plates or steel coils together to create a cylindrical shape. The welding process used can be either electric resistance welding (ERW) or submerged arc welding (SAW).
Welded steel pipes are commonly used in various industries, including oil and gas, construction, and water supply. They are known for their strength, durability, and ability to withstand high pressure and temperature conditions.
