High-Quality ASTM A234 WPB Seamless Pipe Caps
The supplied products were manufactured according to ASME B16.9 dimensional requirements using ASTM A234 WPB carbon steel material. These seamless pipe caps are widely used in oil & gas, petrochemical, power generation, water treatment, and industrial pipeline systems.

Haihao Group carefully controlled the production process to ensure:
- Accurate dimensions and wall thickness
- Smooth bevel ends for easy welding
- Stable mechanical properties
- Clean surface condition
- Full material traceability
