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: the difference between the manufacturing process: galvanized steel pipe and ordinary steel pipe are two categories of steel pipe, galvanized refers to the surface of the steel pipe galvanized, ordinary steel pipe is not. 2, the difference in durability: galvanized pipe corrosion resistance, ordinary steel pipe can bear higher pressure. Galvanized steel pipe is not easy to rust because of the protection of zinc, galvanized steel pipe is lighter than ordinary steel pipe. 3, the difference in use: galvanized steel pipe is generally used to do fences, fences, guardrail, etc.. Widely used in municipal engineering, roads, factories, schools, development zones, gardens, squares, residential areas and other places. Ordinary steel pipe is now basically replaced by galvanized steel pipe.
