Under certain other conditions, increasing the welding speed will reduce the welding heat input, thereby reducing the weld width and penetration. Since the amount of welding wire metal deposition per unit length of the weld is inversely proportional to the welding speed, it also leads to The weld reinforcement is reduced.

Low temperature seamless steel pipe are mainly used in the production of ethylene, propylene, urea, synthetic ammonia, compound fertilizers, and other process equipment.

Long-distance oil and gas pipelines are an important way to ensure energy. In the anti-corrosion construction process of oil and gas pipelines, the surface treatment of straight seam steel pipes is one of the key factors that determine the anti-corrosion service life of the pipeline.

Thick-walled straight seam steel pipes are generally not magnetic or weakly magnetic, but if they are magnetic, they will not affect us during use, but for many manufacturers, it is still necessary to clean the magnetic properties of thick-walled straight seam steel pipes.

It can be said that more and more industrial companies will use seamless steel pipes. Some companies have also found that in the process of using this kind of pipe, there may be a situation of corrosion sometimes.

Under normal circumstances, the seamless steel pipes used daily are of normal caliber, and small-caliber seamless steel pipes are used in some special places.
