Which is better, spiral welded steel pipe or welded steel pipe
1. The materials are the same but the uses are different, so there is no question of who is better. 2. Spiral welded steel pipe refers to a steel pipe with seams on the surface, which is made by bending and deforming steel strips or steel plates into circular, square, and othe...Read more -
What are the insulation methods for anti-corrosion steel pipes
Anti-corrosion steel pipe is a common steel pipe. To slow down and prevent the steel pipe from corroding and depreciating under the chemical and electrochemical effects of internal and external media, or due to the metabolism of microorganisms, it is necessary to do a good job...Read more -
Three common connection methods for 3PE anti-corrosion steel pipes
(1) Welding connection: If there is no need to disassemble, you can choose welding. This is a more traditional connection method. It has a simple structure and can directly connect components of any form. It is economical to use materials and does not weaken the cross-section....Read more -
The difference between cold-drawn steel pipe and hot-rolled steel pipe
The difference between hot processing and cold processing is: that hot rolling is hot processing, and cold drawing is cold processing. The main difference is: that hot rolling is rolling above the recrystallization temperature, cold rolling is rolling below the recrystallizati...Read more -
