  • large diameter steel grade 345 steel pipe

  • Generally speaking, the duration of the "exhalation" of the large diameter steel grade 345 steel pipe is longer than that of the "inhalation" of the large diameter steel grade 345 steel pipe every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the large diameter steel grade 345 steel pipe location, open area of the large diameter steel grade 345 steel pipe, atmospheric pressure, filling degree of large diameter steel grade 345 steel pipe, etc. When the large diameter steel grade 345 steel pipe is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.

Main characteristics of 12Cr1MoV Steel: compared with 12CrMoV steel, 12Cr1MoV steel has higher oxidation resistance and thermal strength. The creep limit of 12Cr1MoV steel is very close to the endurance strength value, and it has high plasticity under the condition of endurance tension; the processability and weldability of 12Cr1MoV steel are good, but it needs to be preheated to 300 °C before welding, and stress removal treatment after welding. 12Cr1MoV steel is widely used in Superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical utility boiler.
