Anti-corrosion steel pipes are classified according to different ways Anti-corrosion steel pipe refers to the steel pipeline which can effectively prevent or slow down the corrosion phenomenon by chemical or electrochemical reaction during transportation and use after anti-corrosion process processing. According to China’s statistics, the annual domestic steel pipe corrosion direct economic loss of more […]
Anti-corrosion properties of common anti-corrosion steel pipes What are the anticorrosive properties of common anticorrosive steel pipes? Solvent-free epoxy coating with matching curing agent low viscosity, cured coating with good anti-corrosion properties, hardness toughness and denseness. And have a relatively suitable application period and curing period. In addition to the excellent insulation and chemical stability […]
Spiral steel pipe development and main production methods The proportion of spiral steel pipe in the steel pipe has stabilized in recent years at about 42% to 45%, with a rising trend of welded pipe. Spiral steel pipe compared with welded steel pipe is the reliability of the material and variety of adaptability, especially adapted […]
Common methods of inspecting the quality of spiral pipes from appearance When many users buy a spiral tube, because there is no professional testing equipment, at this time, the quality of the spiral tube can only be detected from the appearance. The following are several common judgment methods. 1. From the surface of the spiral […]
If the selected cooperative spiral steel pipe factory has a good reputation, the above situation will be greatly avoided. How to evaluate the credibility index of the spiral pipe factory requires careful observation and a cool head. The following are some points of view, please refer to them. 1. When cooperating with a spiral steel […]
Spiral steel pipe is a spiral seam steel pipe made of strip steel coil as raw material, often warmly extruded, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe feeds the strip into the welded pipe unit. After rolling by multiple rollers, the strip is gradually rolled up to form […]
Hot-dip galvanized pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is […]
When using galvanized steel pipe, it is necessary to use welding to make the connection. In order to ensure a good seal, there are some issues to be aware of. When using the rolling groove method to weld galvanized steel pipe, the rolling groove weld will be prone to cracking. In fact, this situation can […]
The cold rolling of seamless steel pipe is to change the martensite to the seamless steel pipe before the rolled piece enters the finishing extruder. Rough rolling is still carried out in full martensitic conditions, and then the hot-rolled strip temperature is reduced to a change of Click below. The nitriding treatment method of seamless […]
In the present life, the use of seamless steel pipe is particularly widespread, but we know that because of the material of seamless steel pipe, we should pay attention to the matters related to the preservation of seamless steel pipe to avoid rusting. Because of the material of seamless steel pipe, if it is left […]
