4.2 Weld End Preparation (per ASME B16.25)
- Bevel Angle: 37.5° (±2.5°)
- Root Face: 1.6 mm (1/16″) nominal
- Counterbore (if required): To match pipe schedule (e.g., Sch. 160, XXS) – specified by purchaser.
- End Preparation: Standard V-groove bevel for butt welding.
Note: Actual end preparation details (counterbore depth, bore diameter) should be confirmed based on the mating pipe schedule and project specifications.

- Features & Applications
- Key Features:
- High Strength: Class 2500 rating for extreme high-pressure systems.
- Forged Body: Open Die Forging ensures a continuous grain structure, eliminating porosity and defects for maximum reliability.
- Erosion Resistance: Seat and gate surfaces are typically hard-faced with Stellite to resist wire drawing and corrosion.
- High-Temperature: Flexible graphite packing provides reliable sealing up to 650°C.
- Butt-Weld Ends: Allows permanent, leak-free installation into piping systems, suitable for high-pressure and high-temperature applications.
- Main Applications:
- High-Pressure Steam Systems (Power Plants)
- Hydrocracking Units (Refineries)
- Wellhead / Choke Manifolds (Oil & Gas)
- High-Pressure Gas Transmission Lines
