What are the uses of seamless steel pipes
The difference between seamless steel pipes and other long strips is that there are no seams around them, and the steel pipe section is hollow. Due to different cross-sectional shapes, they are often classified into round steel pipes and heterogeneous steel pipes. In terms of actual use efficienc...Read more -
What is the difference between welded steel pipe and welded spiral steel pipe
Welded steel pipe refers to a steel pipe with seams on the surface, which is made by bending and deforming steel strips or steel plates into circular, square, and other shapes and then welding them. The blank used for welded steel pipes is a steel plate or strip. Since the 1930s, with the rapid d...Read more -
Application of straight seam steel pipes in pressure pipelines
The nominal diameter of straight seam steel pipe refers to the series of diameter dimensions specified in the standard of straight seam steel pipe. For straight seam steel pipes, pipe fittings, valves, etc., the nominal straight seam steel pipe diameter is represented by a series specified in the...Read more -
The difference between thin-walled spiral steel tubes and thick-walled spiral steel tubes
Thin-walled spiral steel pipe concept: The strip steel is fed into the welded pipe unit. After rolling with multiple rollers, the strip steel is gradually rolled up to form a circular tube blank with an opening gap. The reduction amount of the extrusion roller is adjusted to make the weld gap Con...Read more -

The difference between hot-dip galvanized steel pipe and cold-dip galvanized steel pipe
Galvanized steel pipes are divided into cold-dip galvanized steel pipes and hot-dip galvanized steel pipes. The former has been banned, and the latter has been advocated by the country to be temporarily used. Hot-dip galvanized steel pipe. Hot-dip galvanizing pipe reacts molten metal with an iron...Read more -
Details of H-shaped steel
H-shaped steel is an economical cross-section profile with a cross-section shape similar to the capital Latin letter H. It is also called a universal steel beam, wide-edge (edge) I-beam, or parallel-edge (flange) I-beam. It is different from the one that has been used in China for a long time. Ho...Read more -
The difference between cold-drawn seamless steel pipe and hot-rolled seamless steel pipe
Cold drawn (rolled) seamless steel pipe: round tube blank → heating → perforation → heading → annealing → pickling → oiling (copper plating) multi-pass cold drawn (cold rolled) billet → heat treatment → straightening → Hydrostatic test (flaw detection) mark → Warehouse. Hot rolled (extruded seaml...Read more -
