What kind of steel pipe is GB8163+20#+ANTI-HIC? Can common GB8163 20# seamless pipes be used as a substitute? If it’s not possible, where can I buy such tubes?
1. Chemical composition: The levels of P and S must be kept below 0.020% and 0.015%, respectively； 2. Yield strength should be less than 345 MPa ； 3. The material must be silicon-killed steel. 4. It must comply with the requirements of NACE MR0175. 5. The carbon equivalent CE should be less than 0.42%. 6. There must be no sharp defects on the surface of the material that are larger than 0.5 mm. 7. The material must be delivered after heat treatment; it cannot be replaced with ordinary 20# steel
The 20#ANTI-HIC steel pipe seems to be a steel pipe resistant to hydrogen-induced cracking
20#ANTI-HIC: Steel resistant to hydrogen-induced cracking; currently, there are no relevant standards in China, with each engineering company using its own design standards.
