Magnetic arc blowing phenomenon in steel pipe welding
During the welding operation, the phenomenon that the magnetic arc blowing affects the welding process sometimes occurs. The formation of the magnetic arc blow is the result of the presence of residual magnetism in the pipe metal. Generally, residual magnetism is divided into two types: inductio...Read more -
Steel Pipe Making Machine Installation Precautions
1. For raw materials, if you want to use stainless steel welded pipe equipment for normal processing, you must pay attention to the problems of the raw materials during transportation or loading and unloading, and try not to cause bumps or scratches. 2. For the used site, the processing site sh...Read more -
Seamless Steel Pipe and Welded Steel Pipe Difference
Seamless Steel Pipe 1.Appearance, seamless steel pipe and welded steel pipe have different welding reinforcement on the welded pipe wall 2.Pressure, Seamless pipes require higher pressure during production. Welded pipes usually have about 10 MPa when manufactured. 3. The seamless steel pipe is f...Read more -
Steel Pipe Making Machine Production Efficiency
With the same pipe diameter and thickness, the same output power, the Steel Pipe Making Machine speed on site can be fast or slow. When the tube mill equipment is the same as the steel belt, the main factor affecting the welding speed is mostly the welding process. If the welding is not good, cr...Read more -
Judge the quality of stainless steel pipe
There are many types of stainless steel, so there are many ways to judge the quality of stainless steel pipes. At room temperature, there are two types of stainless steel pipes: austenitic and ferrite. The austenitic type is non-magnetic or weakly magnetic, and the martensitic or ferrite type is ...Read more
