Engineered for Low-Temperature Service
The ASME B16.9 WPL6 fittings supplied for this project are intended for low-temperature pipeline applications where conventional carbon steel may experience reduced toughness. SA-420 WPL6 is a widely recognized material for cold-service piping systems because of its excellent impact resistance and weldability.
To meet the customer’s technical requirements, the fittings were manufactured and inspected to achieve:
- Qualified metallographic structure
- Stable mechanical properties
- Compliance with low-temperature impact testing requirements
- Dimensional accuracy according to ASME B16.9
- Full EN 10204 Type 3.2 inspection certification
These characteristics make the fittings suitable for LNG facilities, natural gas systems, petrochemical plants, offshore platforms, and other pipeline projects operating under low-temperature conditions.
Strict Quality Assurance
Haihao Group follows comprehensive quality control procedures throughout production. For this shipment, the inspection and testing program included:
- Raw material verification for SA-420 WPL6
- Dimensional inspection according to ASME B16.9
- Metallographic examination
- Mechanical property testing
- Low-temperature impact testing
- EN 10204 Type 3.2 inspection certification
- Final visual inspection prior to shipment
These procedures ensure that every ASME B16.9 WPL6 fittings product delivered to the customer meets the required quality standards and is ready for reliable installation.
