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 -
Inspection standards and welding control problems of thick-walled steel pipes
In the production of thick-walled steel pipes, thermal expansion pipes, etc., strip steel is used as the raw material for production, and the pipes obtained by thick-walled welding on high-frequency welding equipment are called thick-walled steel pipes. Among them, according to the different uses...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 -
How to install stainless steel pipe fittings
1. The arc starting of stainless steel pipe fittings adopts the reflow method, and the arc ending adopts the method of full arc crater. The over-weighing of arc starting should be completed in the slope, and arcing and arc starting cannot be performed on the surface of the pipeline and pipe fitti...Read more -

They are 20 key products developed by our country. Straight seam steel pipe is used for l...Read more -
The main purpose of thick-walled steel pipe
There is a big difference between thick-walled steel pipes and thin-walled steel pipes in terms of wall thickness. If the wall diameter of the steel pipe is greater than 0.02, we generally call it a thick-walled steel pipe. Thick-walled steel pipes have a very wide range of applications, and beca...Read more
