Scope: This standard specifies the hardness control requirements for the prevention of sulfide stress cracking (SSC) in welds of steel pipes and equipment in wet hydrogen sulfide-containing sour oil and gas environments. This standard applies to the welds of SSC-resistant low-carbon steel and low-alloy steel pipes and equipment that can be used in SSC Zones 1, 2 and 3 in sour environments specified in SY/T 0599. The equipment to which this standard applies includes pressure vessels, process piping, heat exchangers, atmospheric storage tanks, valve bodies, pump and compressor housings, etc.
