The effect of the oxide layer. On the one hand, the oxidation layer reduces the wall thickness of the 12Cr1MoV steel pipe, on the other hand, the heat transfer

The 10CrMo910 steel pipe works at high temperature. It is subjected to static load, fatigue or impact load, and has a certain strength, oxidation resistance and

In order to guarantee the performance of 13CrMo44 steel pipe base metal and weld, besides the control of welding process, it is very important to preheat the 1

13CrMo44 steel pipe generally has the following characteristics during welding:Hardenability. The hardening property of the 13CrMo44 steel pipe depends on its
