| High Light | ASME SA-516 Grade 70 pressure vessel ，HIC/SSC resistant pressure vessel ，25 MPa sour service pressure vessel | ||
We engineer and manufacture high-integrity ASME Section VIII Division 1 U-Stamped carbon steel pressure vessels specifically for sour service environments in the oil and gas sector. Designed to resist wet H₂S damage, such as Hydrogen-Induced Cracking (HIC) and Sulfide Stress Cracking (SSC), these vessels ensure long-term mechanical reliability in demanding upstream processing, refining, and gas treatment facilities.
To withstand wet sour environments, every pressure-retaining component complies strictly with ASME Section VIII, Div 1 and NACE MR0175 / ISO 15156 standards:
Quality control follows rigorous ASME and NACE testing protocols:
| Inspection / Test Type | Standard & Requirement | Acceptance Criteria |
|---|---|---|
| HIC / SSC Resistance | NACE TM0284 / NACE TM0177 | Zero cracks (CLR/CTR/CSR per spec) |
| Impact Testing | ASME Sec VIII Div 1 Charpy V-Notch | -29°C to -46°C per Design Temp |
| Non-Destructive Examination | ASME Sec V (100% RT / UT on welds) | UW-51 / UW-52 Compliance |
| Post-Weld Heat Treatment | ASME Sec VIII Div 1 (PWHT) | Full stress relief (595°C-650°C) |
| Hydrostatic Test | ASME Sec VIII Div 1 UG-99 | 1.3 × Maximum Allowable Working Pressure |
Our engineering capability covers complete thermal-hydraulic and mechanical design. Every sour service vessel is delivered with full material traceability and complete NDT documentation. We integrate custom nozzle configurations, internal baffles, and mist eliminators directly into your skid-mounted modules.
