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.

  1. 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
