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 -
The difference between thin-walled spiral steel pipe and thick-walled spiral steel pipes
The concept of thin-walled spiral steel pipe: the strip steel is fed into the welded pipe unit, rolled by multiple rollers, the strip steel is gradually rolled up to form a circular tube billet with an opening gap, and the reduced amount of the extrusion roller is adjusted to make the weld seam g...Read more -
How to store spiral steel pipe
1. It is necessary to store the spiral steel pipe in the warehouse, not to store it in the open air, and it is necessary to ensure that the storage in the warehouse is clean. Clean and well drained. If there are weeds or other debris on the ground, it needs to be cleaned and stored. This is to ke...Read more
