How to Production a Steel Reducer
Chemical pipe fittings are used to connect two pipes with different diameters. According to different shapes, they are divided into two types: concentric steel reducers and eccentric steel reducers. The reducer materials include stainless steel reducer (304, 304l, 316, 316l), alloy steel reducer,...Read more -
How to identify counterfeit thick-walled seamless steel pipe
1. Fake and inferior thick-walled seamless steel pipes are prone to folding. Folds are various fold lines formed on the surface of thick-walled seamless steel pipes. This defect often runs throughout the longitudinal direction of the product. The reason for folding is that shoddy manufacturers pu...Read more -
Troubleshooting and production technology of straight seam steel pipes
Straight seam steel pipes are steel pipes with welds that are longitudinally parallel to the steel pipe. They are usually divided into metric electric welded steel pipes, electric welded thin-walled pipes, transformer cooling oil pipes, etc. The production process of straight seam welded pipe is ...Read more -
Quality requirements for large diameter thick wall seamless steel pipes

Steel pipe processing methods
Steel pipe processing and furnace installation: 1. Workpieces that are easily deformed during heat treatment should be heated on a special fixture. 2. The workpiece should be placed in the effective heating zone Warm-up: 1. For workpieces with complex shapes or sharp changes in cross-section and ...Read more -
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 -
