Haihao Group Delivers Seamless WPL6 Eccentric Reducers to Kazakhstan
Hebei Haihao High Pressure Flange Pipe Fitting Group Co.,Ltd is proud to announce the successful shipment of specialized piping components to a major project client in Kazakhstan. This order features high-specification butt-weld eccentric reducers designed for demanding low-temperature and sour gas environments, reinforcing Haihao Group’s expertise in critical energy sector supplies.
Seamless Butt Weld Eccentric Reducer in ASTM A420 WPL6 material
Engineering for Extreme Conditions: The WPL6 Difference
The core of this delivery is the eccentric pipe reducer, meticulously manufactured to meet stringent international codes and service requirements:
| Product Name | Specification | Material Grade | Key Standards | Service Requirement |
| Butt-Weld Eccentric Reducer | DN 150 x 80 mm (6″ x 3″) | ASTM A420 Grade WPL6 | ASME B16.9, NACE MR01-75 | Sour Service, Low Temperature |
The choice of ASTM A420 Grade WPL6 is non-negotiable for this application. As a low-temperature carbon steel fitting, WPL6 is specifically heat-treated and impact-tested to ensure maximum toughness and resilience down to temperatures as low as -46℃ (-50℉), essential for reliable operation in the harsh winter climate of Kazakhstan.
Furthermore, the requirement for NACE MR01-75/ISO 15156 compliance confirms the reducers are fully optimized for sour service (H₂S-containing) environments, mitigating the risk of sulfide stress cracking (SSC) and ensuring long-term asset integrity.
Precision Manufacturing and Certification
Key features of these reducers include:
- Seamless Construction: Manufactured via the seamless process, these reducers offer superior structural integrity and higher performance reliability compared to their welded counterparts, particularly important in high-stress and low-temperature applications.
- Dimensional Accuracy: Designed to ASME B16.9 standards with a consistent Schedule 40 (SCH40) wall thickness (7.11 mm to 5.49 mm), ensuring perfect alignment and fit-up during butt-welding.
- Full Traceability: The entire batch is supplied with Type 3.1 Certification as per EN 10204:2004, providing complete material traceability, chemical composition, and mechanical test results for quality assurance.
This delivery to a major Kazakhstan oil and gas facility solidifies Haihao Group’s position as a reliable global partner capable of supplying specialized, highly-certified fittings for the world’s most challenging energy projects.
