Classification of welding methods:
According to different welding methods, it can be divided into arc welding pipe, high frequency or low frequency resistance welding pipe, gas welding pipe, furnace welding pipe, bandi pipe, etc.

Electric welded steel tube: used for oil drilling and machinery manufacturing.

Furnace welding pipe: can be used as water gas pipe, straight welded pipe for high pressure oil and gas transmission; Spiral welded pipe is used for oil and gas transportation, pipe pile, bridge pier and so on.
