Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding. Large-diameter or thicker welded pipes are generally made of steel billets directly, while small welded pipes and thin-walled welded pipes are generally made of steel strips directly welded. The production process of welded steel pipe is simple, the production efficiency is high, and there are many varieties and specifications.
Classification of welded steel pipes
Classification according to the form of weld:
Straight seam welded pipe and spiral welded pipe
Classification by production process:
Arc Welded Pipe, Electric Resistance Welded Pipe, High Frequency/Low Frequency Gas Welded Pipe, Furnace Welded Pipe
Classified by section shape:
(1) Simple section steel pipes - round steel pipes, square steel pipes, oval steel pipes, triangular steel pipes, hexagonal steel pipes, diamond steel pipes, octagonal steel pipes, semi-circular steel pipes, and others.
(2) Steel pipes with complex sections - unequal hexagonal steel pipes, five-petal plum-shaped steel pipes, double-convex steel pipes, double-concave steel pipes, melon-shaped steel pipes, conical steel pipes, corrugated steel pipes, case steel pipes, and others.
Classification by wall thickness:
Thin-walled steel pipe, thick-walled steel pipe.
