Classification of folding welding methods for welded steel pipes
According to different welding methods, it can be divided into arc welded pipe, high-frequency or low-frequency resistance welded pipe, gas welded pipe, furnace welded pipe, Bondi pipe, etc. Welded steel pipe: used in oil drilling and production and machinery manufacturing.
Furnace welded pipe: it can be used as water gas pipe, large diameter straight seam welded pipe for high-pressure oil and gas transportation, etc; Spiral welded pipe is used for oil and gas transportation, pipe pile, pier, etc.
Folds are classified by weld shape
It can be divided into straight seam welded pipe and spiral welded pipe
Folding straight seam welded pipe
Simple production process, high production efficiency, low cost and rapid development.
According to the purpose, it is divided into general welded pipe, galvanized welded pipe, oxygen blowing welded pipe, wire sleeve, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welding thin-wall pipe, electric welding special-shaped pipe and spiral welded pipe.
