Buttweld Fittings
Buttweld Fittings are essential components used to change the direction, branch, or diameter of piping systems in a permanent, welded manner. Manufactured from seamless or welded pipes, these fittings are preferred for high-pressure and high-temperature applications in industries like oil & gas, petrochemical, power generation, and shipbuilding. They ensure smooth fluid flow, minimal pressure drop, and superior mechanic
- Smooth internal surface ensures low pressure drop
- Permanent and high-strength welded joints
- Available in wide range of sizes and schedules
- Manufactured to global standards (ASME, DIN, EN)
- Ideal for high-pressure and high-temperature pipelines
