Spiral steel pipe development and main production methods

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

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 […]

How to choose the spiral pipe factory

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 […]

The relationship between the length of the spiral steel pipe and the price

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 […]

How to prevent white rust from hot-dip galvanized seamless steel pipe manufacturers?

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 […]

How to eliminate the problems that are easy to occur in the connection of galvanized steel pipes

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 […]

Cold Rolled Nitriding Treatment of Seamless Steel Tubes

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 […]
