The seam of the steel pipe is called welded pipe, according to the weld is divided into: straight seam welded pipe, spiral welded pipe.
First, the classification of pipe materials
1. Classification according to the production method
(1) Seamless pipe-
Hot rolled pipe, cold rolled pipe, cold pull pipe, extrusion pipe, pipe jacking
(2) Welded pipe (welded steel pipe)
(a) According to the process of one arc welding pipe, resistance welding tube (high frequency, low frequency), gas welding pipe, furnace welding pipe
(b) weld pipe and spiral pipe according to the weld
2. Classification according to the section shape
(1) Simple section steel pipe a circular steel pipe, square steel pipe, oval steel pipe, triangular steel pipe, hexagonal
Steel pipe, diamond steel tube, octagonal steel tube, semicircular steel circle, others
(2) Complex section steel pipe unequal hexagonal steel pipe, five-shaped steel pipe, double convex steel pipe, double concave
Steel pipe, melon seed shaped steel pipe, conical steel pipe, corrugated steel pipe,
Case steel pipe, others
3. Classification thin-wall steel pipe and thick-wall steel pipe according to wall thickness
4. Classification by use 1
Steel pipe for pipe, thermal equipment, steel pipe for mechanical industry, petroleum, geology
Steel pipe for drilling, container steel pipe, steel pipe for chemical industry, special use
Road steel pipe, other
