Improving the Wall Thickness Accuracy of Reinforced 3PE Anti-corrosion Steel Pipe
Now the application of reinforced 3pe anti-corrosion steel pipe is more, however, because the wall thickness accuracy of reinforced 3pe anti-corrosion steel pipe is not high, there is a phenomenon of uneven thickness, which will have a great impact on the performance of reinforced 3pe anti-corros...Read more -
What are the heat treatment methods for spiral steel pipes
1. Thermomechanical treatment: High-temperature thermomechanical treatment can improve the yield ratio and elastic limit of spiral steel pipe. Improve the comprehensive mechanical properties, fatigue properties, and stress relaxation properties of the spiral steel pipe. Reducing the ductile-britt...Read more -
Classification of anti-corrosion steel pipes for natural gas
1. IPN8710 anti-corrosion steel pipe: when there are many kinds of corrosive media in the steel pipe, such as acid, alkali, salt, oxidant, and water vapor, the coating must be chemically inert, resistant to acid, alkali, and salt corrosion, and the coating film should have a dense structure and w...Read more -
Coated steel pipe details
The steel-plastic composite pipe is made of hot-dip galvanized steel pipeas the substrate, and the inner wall (or outer wall if necessary) is coated with plastic by powder fusion spraying technology, with excellent performance. Compared with galvanized pipe, it has the advantages of anti-corrosio...Read more
