What are the details of thick-walled steel pipe before use
The welding method of thick-walled steel pipes should be selected according to the material and wall thickness of thick-walled steel pipes. Because different welding methods have different arc heat and arc force, different welding methods have different characteristics. For ex...Read more -
Advantages of plastic-coated steel pipes for fire water supply
In the case of no pipe blockage or water blockage, the plastic-coated steel pipe successfully solves the problems of coating burial, steel pipe corrosion, scaling, etc., and prolongs the service life of the fire water supply pipe. Epoxy powder anti-corrosion steel pipe has goo...Read more -
Routine maintenance and production process of thick-walled straight seam steel pipe
The advantage of thick-walled straight seam steel pipe is that the online heat treatment process of the weld eliminates the welding stress, refines the metallographic grains of the heat-affected zone, and improves the physical and mechanical properties. The direction of struct...Read more -
Three connection methods of large-diameter spiral steel pipes
The most commonly used connection method for large-diameter spiral steel pipes is welding, but in some projects, threaded connections, flange connections, socket connections, groove connections, etc. are often used. Welding and flange connection: Welding and flange connection ...Read more -
What problems should be paid attention to when welding galvanized steel pipe
1. The premise must be polished: the galvanized layer at the weld must be polished off, otherwise, bubbles, trachoma, false welding, etc. will occur. It will also make the weld brittle and reduce the rigidity. 2. Welding characteristics of galvanized steel: Galvanized steel is...Read more -
What are the heat treatments of stainless steel welded pipe
During the production process of stainless steel welded pipe, intermediate heat treatment, and finished heat treatment can be carried out. Because a bright surface without oxidation can be obtained, the traditional pickling process is canceled. The use of this heat treatment p...Read more -
Surface defects of seamless steel pipes and their causes
The causes of surface defects of seamless steel pipes are intricate. There are hundreds of influencing factors listed, and sometimes there are dozens of factors for the same defect, and the occurrence of defects has a great relationship with the steel type. This is why the pro...Read more -
