Welded carbon steel pipe is the most economical and durable ways to connect the pipes together. The raw material used for welded steel pipe is steel plate or strip steel. According to different standards and requirements, there are many kinds of steel strip materials.
The most commonly used material is Q195-Q345: the Q195 similar to a283 GR.B, 040A10, SS330, SPH the Q235 similar to a283 GR.B, 080A15, the Q345 similar to a737 GR.B, SS400, S235JR, SKT500
Welded carbon steel pipes is widely used in fluid pipelines, power plants, structural tubes, high and low pressure boiler tubes, scaffold tubes, pharmaceuticals and construction.
