Analysis of pressure grade of carbon steel spiral steel pipe
The pressure ratio of the spiral steel pipe on the gas pipeline also tends to decrease gradually. For pipe diameter, pressure, and pressure ratio, optimization calculation and comparison are required. When the output is determined and the pipe diameter, pressure, and pressure ratio are determined...Read more -
Forming Technology of Thin Wall Welded Steel Pipe
1. Downhill forming method: Downhill shaping of welded steel pipe equipment can significantly reduce edge extension. 2. Increase the middle extension of the billet: During the forming process, the reduction of the opening pass pattern is increased, so that the gap between the upper and lower roll...Read more -
What does the hot rolling process in stainless steel pipe fittings mean
Simply put, the process of rolling stainless steel pipe fittings after heating and controlling them above the recrystallization temperature is called hot rolling. The process of rolling below the recrystallization temperature, including at room temperature, is called cold rolling. Hot-rolled stee...Read more -
What advantages of steel pipe fitting tees
1. It completely solves the problem of mutual friction between the closed surfaces of traditional connecting pipes and affects the sealing; the flow resistance is small, and the resistance coefficient of the stainless steel tee is equal to that of the pipe section of the same length; 2. The stain...Read more -
Application of straight seam steel pipes in pressure pipelines
The nominal diameter of straight seam steel pipe refers to the series of diameters specified in the standard for straight seam steel pipes. For straight seam steel pipes, pipe fittings, valves, etc., the nominal straight seam steel pipe diameter is represented by the series specified in the stand...Read more -
Two Possibilities of Surface Defect Formation of Spiral Steel Pipe
There are two possibilities for the formation of surface defects in spiral steel pipes: one is that the plasticity of the material itself is not good during the deformation process, resulting in cracks and outward folding; Cracks and folds. 1. Thermal simulated tensile test results and analysis T...Read more
