Quality requirements for seamless steel pipes
1. Chemical composition of steel: The chemical composition of steel is the most important factor affecting the performance of seamless steel pipes, and it is also the main basis for formulating the parameters of the rolling process and heat treatment of seamless steel pipes. (1) Alloying elements...Read more -
Internal and external anti-corrosion measures of steel pipelines
1. The common method of external anticorrosion of steel pipes: using cathodic protection alone is not economical due to too much power consumption. Therefore, the combined protection of the anti-corrosion layer and cathodic protection, the cathodic protection that will be concentrated on the expo...Read more -
Product advantages of anti-corrosion steel pipe
1. Combining the mechanical strength of steel pipe and the corrosion resistance of plastic; 2. The outer wall coating of the anti-corrosion steel pipe is more than 2.5mm, which is scratch-resistant and bump-resistant; 3. The friction coefficient of the inner wall of the anti-corrosion steel pipe ...Read more -
Wall Thickness Accuracy and Straightening Method of Straight Seam Steel Pipes
The control of the wall thickness of the straight seam steel pipe is a difficult point in the production of steel pipes. At present, the methods of straight seam steel pipe manufacturers in the production of wall thickness accuracy generally include: 1. Tube billet heating: the heating should be ...Read more -
Comparison of technical characteristics of spiral steel pipe and straight seam steel pipe
Spiral steel pipes and straight-seam steel pipes have different technical characteristics and production processes. They have many differences and differences in production, have different functions and uses, and their values in use are also different. The technical characteristics of spiral stee...Read more -
How to detect the corrosion performance of steel flange
The use of steel flanges in industrial structural parts is mainly to improve the connection and keep the pipelines sealed without leakage. However, many steel flanges will corrode and age after being used for some time, thus losing their tightness. Therefore, it is very necessary to conduct anti-...Read more
