What are the quality requirements for seamless steel pipes
Seamless steel pipes are long strips of steel with a hollow cross-section and no seams around their perimeter. Due to their hollow cross-section, seamless steel pipes are widely used as pipelines for transporting fluids, such as oil, natural gas, coal gas, water, and certain s...Read more -
What are the processes involved in pickling and passivation of stainless steel pipes
First, the principle of pickling and passivation of stainless steel pipes. The corrosion resistance of stainless steel pipes is mainly due to the addition of a high content of chromium (Cr). Cr is easily oxidized, rapidly forming a dense Cr2O3 oxide film on the steel surface. ...Read more -
What are the industrial characteristics and production process details of Q355GNH straight seam welded pipe
First, the characteristics of Q355GNH straight seam welded pipe. Q355GNH straight seam welded pipe uses Q355GNH steel plate as raw material and is manufactured through high-frequency welding or submerged arc welding processes. Q355GNH steel is a low-alloy high-strength structu...Read more -
What to do if 316L thick-walled stainless steel pipes corrode
Due to their corrosion resistance, impact resistance, and high-temperature resistance, 316L thick-walled stainless steel pipes are commonly used in pharmaceuticals, chemicals, food processing, light industry, chemical machinery, industrial pipelines, and mechanical parts. They...Read more -
What are the requirements for non-destructive testing (NDT) of spiral welded steel pipes
The main NDT methods for spiral welded steel pipes include ultrasonic testing, radiographic testing, eddy current testing, magnetic particle testing, and penetrant testing. Ultrasonic testing is frequently used. Ultrasonic testing has high sensitivity for area-type defects ins...Read more
