GB/T 27866-2011 《Specification of controlling weld hardness of carbon steel and low alloy steel piping and equipment to prevent sulfide stress cracking》 Related products

Hardness control requirements to prevent sulfide stress cracking (SSC) of steel piping and equipment welds in acidic environments containing hydrogen sulfide apply to low carbon steel and low alloy steel piping and equipment welds. The standard applies to equipment such as Pressure Vessels, process piping, heat exchangers, etc. Hardness control is designed to reduce the risk of weld failure in acidic oil and gas environments and provide technical support for the safe use of related equipment.
