BUTTWELD FITTINGS

Butt-weld (BW) fittings are essential components used in industrial pressure piping systems to change flow direction, connect pipes of different sizes, or provide branch lines.

They are permanently joined to the piping system via circumferential welding, ensuring a high-integrity, leak-proof connection with a smooth internal flow.

Key Features

  • Connection Method: Butt welding creates a strong, durable, and permanent joint that is ideal for high-pressure and high-temperature applications.
  • Standards: Dimensions are governed by standards such as ASME B16.9 (American) and BS EN 10253 (European).
  • Material: Available in a wide variety of materials to suit different applications and fluid properties, including:
    • Carbon Steel: ASTM A234 WPB (most common).
    • Stainless Steel: 304/304L and 316/316L (ASTM A403 grades).
    • Alloy Steel: ASTM A420 WPL6 (for low-temperature service).

Pressure Rating: Pressure ratings are determined by the pipe's wall thickness (schedule number, e.g., Schedule 10, 40, 80, XXS), rather than a specific pressure class.
