Why industrial boiler pipes are seamless steel pipes
The pipes for industrial boilers are mainly seamless steel pipes because the performance indicators of seamless steel pipes can fully meet the requirements of boiler applications. Although the cost is high, their safety and reliability are high. Welded steel pipes are generally used within 2Mpa a...Read more -
Characteristics and application scope of construction method of thin-wall stainless steel tube socket and socket argon arc welding
Features: 1. The welding process does not require welding consumables (replaced by the expanding edge), the steel pipe is inserted into the socket of the pipe fitting. The end of the socket is welded by argon tungsten arc welding (GTAW) so that the pipe is fused into one, not only can The welding...Read more -
Different types and appearance requirements of straight seam steel pipes
The high-frequency welding process of straight seam steel pipe is completed in the high-frequency welded pipe unit. The high-frequency welded pipe unit is usually composed of roll forming, high-frequency welding, extrusion, cooling, sizing, flying saw cutting, etc. The front end of the unit is eq...Read more -
What are the causes and detection methods of oil and gas pipeline leakage
There are many reasons for pipeline leakage, which can be mainly divided into three categories: corrosion perforation, fatigue rupture, and external force damage. Although taking corrosion control measures can significantly slow corrosion, it does not prevent corrosion. When the cathodic protecti...Read more -
Installation requirements for threaded insulating joints for oil casings
1. The insulation joint is installed within 50 meters to avoid the dead end to be welded. 2. After the insulating joint is connected to the pipeline, it is not allowed to lift the pipeline within 5 meters of the joint. Must be pressure tested with the line. 3. After the insulating joint is connec...Read more -
Characteristics of slotted steel pipe
