GB/T 27866-2011
AbolishedSpecification of controlling weld hardness of carbon steel and low alloy steel piping and equipment to prevent sulfide stress cracking
控制钢制管道和设备焊缝硬度防止硫化物应力开裂技术规范
Application Summary AI generated
This standard specifies the hardness control requirements for welds in carbon steel and low alloy steel piping and equipment to prevent sulfide stress cracking (SSC). It is applied in the petroleum, natural gas, and petrochemical industries, particularly for equipment and pipelines handling sour environments containing hydrogen sulfide. The standard is used during fabrication, welding, and post-weld heat treatment processes to ensure weld hardness remains below specified thresholds, thereby mitigating the risk of cracking in service.
