Why ASTM A234 WP91?
ASTM A234 WP91 is a chromium-molybdenum-vanadium alloy steel widely specified for ultra-high temperature and pressure environments, especially in:
- Thermal power plants
- Combined cycle power stations
- Petrochemical and refinery piping
- High-pressure steam pipelines
Its excellent creep resistance, oxidation resistance, and high-temperature strength make WP91 fittings a preferred choice for critical piping systems.
Manufacturing and Quality Control
For this Indonesian project, Haihao Group implemented a complete quality assurance process, including:
- Raw material verification and heat number traceability
- Controlled forming and heat treatment
- Dimensional inspection in accordance with ASME B16.9
- Visual and surface quality inspection before packing
Each WP91 elbow and WP91 equal tee was carefully packaged to ensure safe transportation and on-site readiness.
