How to prevent the spiral steel pipe from being damaged during transportation
1. The fixed-length spiral steel pipe can not be bundled. 2. If the two ends of the spiral steel pipe have threaded buckles, they should be protected by thread protectors. Apply lubricating oil or rust inhibitor to the thread. Both ends of the spiral steel pipe are broken, and pipe protectors can...Read more -
Advantages and installation precautions of steel-plastic composite steel pipe
In recent years, the status of ordinary steel pipes has declined rapidly. The fundamental factor is that environmental corrosion is serious. Even if the wall thickness of the steel pipe is large, it is always unrealistic to use the wall thickness to slow down the corrosion, because the wall layer...Read more -
Matters needing attention when welding spiral steel pipe
Welding and cutting of the spiral steel pipe structure are inevitable in the application of the spiral steel pipe. Because of the characteristics of the spiral steel pipe itself, compared with ordinary carbon steel, the welding and cutting of the spiral steel pipe have particularity, and it is ea...Read more -

Technical oil casing separates pressure at different levels so that d...Read more -
The difference between high frequency welded steel pipe and straight seam welded steel pipe
No. 1. Different nature 1. High-frequency welded steel pipe: After the hot-rolled coil is formed by the forming machine, the skin effect and proximity effect of high-frequency current are used to heat and melt the edge of the tube blank, and pressure welding is performed under the action of the e...Read more
