Designed for Low-Temperature Service
The customer’s project requires piping components capable of operating safely under sub-zero conditions. Therefore, each ASTM A420 WPL6 fittings product was manufactured to maintain mechanical properties at -46°C.
To satisfy the project specification, the fittings achieved:
- Compliance with -46°C low-temperature impact requirements
- Stable mechanical properties after heat treatment
- Metallographic structure meeting Grade 7
- Excellent toughness for cold-service applications
These characteristics make ASTM A420 WPL6 fittings widely used in LNG facilities, gas processing plants, petrochemical projects, offshore platforms, and low-temperature process pipelines.
Precision Manufacturing and Quality Assurance
Quality consistency is one of Haihao Group’s priorities throughout production. Every fitting in this shipment was manufactured under strict process control, including:
- Raw material verification
- Seamless hot forming
- Heat treatment for mechanical property retention
- Dimensional inspection according to ASME B16.9
- Metallographic examination (Grade 7)
- Low-temperature performance verification
- Final visual inspection before packing
These quality procedures ensure every ASTM A420 WPL6 fittings component is ready for reliable installation upon arrival at the project site.
Safe Packaging for International Delivery
To prevent damage during international transportation to the UAE, the seamless elbows and concentric reducers were carefully packaged using export-standard protective materials. Product identification, dimensional markings, and inspection records were checked before shipment, allowing the customer to complete receiving inspections efficiently.
