Galvanized rectangular tube processing is based on the principle of electrolysis. Through the electrolysis process of metal ions, a layer of metal or alloy is deposited on the surface of rectangular tube to change the physical and chemical properties of the rectangular tube surface, and finally make the galvanized sheet have wear resistance, decoration and impact resistance, etc,.

The main factors affecting impact toughness of ERW steel pipe are the physical and chemical properties of raw materials, raw material crystals and non-metallic inclusions and weld heat treatment conditions

Galvanized pipes and stainless steel pipes are widely used, but attention should be paid to details. So what is the difference between galvanized pipe and stainless steel pipe?

When we use the square tube, we sometimes find that the brightness of surface is not enough, which will not only affect the appearance of square tube, but also affect its use effect. So what are factors that affect the surface brightness of square tube?

If the seamless steel pipe is directly placed in a strong alkali or strong acid environment, corrosion will also occur. Therefore, in order to avoid not affecting the use in the later period, it is necessary to do anticorrosion work in advance and maintain it well, so that it can be reasonably applied in production and life.

SSAW steel pipe is a steel pipe with spiral seam, which is made of strip steel coil as raw material, extruded at regular temperature and welded by automatic double-wire double-sided submerged arc welding process. So what do you need to pay attention to when installing SSAW steel pipe?

During the hot rolling process of the rectangular tube, if the problem of oxide scale is encountered, the surface quality will be affected, and the subsequent cold rolling process will also be affected. So how to solve this problem?

ERW steel pipe occupies a pivotal position in the field of transportation pipes in the world. So what are the requirements and advantages of ERW steel pipes during transportation?
