The scope of application of epoxy resin coated steel pipes
Epoxy resin-coated steel pipe coating is a thermosetting plastic that combines the common advantages of steel and plastic. Its scope of application includes 1. Fire sprinkler system and domestic water supply and drainage; 2. Gas drainage, mud transportation, and ventilation sy...Read more -
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 -
Performance comparison between spiral steel pipe and straight seam steel pipe
1. Welding process: In terms of the welding process, the welding methods of spiral steel pipes and straight seam welded pipes are the same, but straight seam welded pipes inevitably have many T-shaped welds, so the probability of welding defects is greatly increased, and the w...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 -
Preparation work before connecting plastic-coated steel pipes
The plastic-coated steel pipe is composed of a core layer, a fastening steel strip, an air layer, a heat insulation layer, a reflective layer, a sliding bracket, an outer protective steel pipe, sprayed polyurethane, and entangled fiberglass. It has high strength, is not easily...Read more -
Welding technology and methods of spiral seam submerged arc welded steel pipe
The inner and outer surfaces of large-diameter spiral submerged arc welded steel pipes should be bright and free of residual acid and oxide scale. The surface should be free of defects such as cracks, inclusions, scarring, delamination, concave welds, and incomplete welding. S...Read more -
Precautions for handling and storing stainless steel pipe at the construction site
After thin-walled stainless steel pipes are packaged and bundled, they should be stored in a dry and clean environment without corrosive gases to avoid disorderly stacking with other items. Because the surface of stainless steel is relatively smooth and bright, and it is a met...Read more
