1. Welded steel pipe is divided into straight seam welded pipe and spiral welded pipe according to the form of weld. Moreover, relatively speaking, the welded pipe of smaller diameter adopts straight seam welding, and the welded pipe of large diameter adopts spiral welding
2, according to the production method classification: process classification - arc welding pipe, resistance 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 round welded pipe and special-shaped (square, rectangular, etc.) welded pipe; According to the different materials and uses, it can be divided into welding steel pipe for mineral fluid transportation, galvanized steel pipe for low pressure fluid transportation, electric welding steel pipe for belt conveyor roller, etc.
4, according to the use and divided into general welding pipe, galvanized welding pipe, blowing oxygen welding pipe, wire casing, metric welding pipe, roller pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welding thin-wall pipe, electric welding pipe, scaffold pipe and spiral welding pipe.
