Types of Buttweld Fittings
Explore our precision-engineered Buttweld Fittings designed for leak-proof and high-strength piping systems.
Buttweld Elbow
Elbows allow directional changes in piping systems, available in 45°, 90°, and 180° bends for smooth fluid flow with minimal pressure loss.
Buttweld Tee
Tees are used to split or combine flow in pipelines, offered in equal and reducing types for
multiple outlet configurations.
Buttweld Reducer
Reducers transition between pipe sizes, available in concentric (center-aligned) and eccentric (offset) types to manage flow and avoid turbulence.
Buttweld Cap
End caps are used to block the end of a piping system, providing secure sealing in high-pressure and high-temperature conditions.
Buttweld Stub End
Stub ends are used with lap joint flanges, making them ideal for systems requiring frequent dismantling for inspection or maintenance.
Buttweld Nipple
Nipples are short pieces of pipe with bevelled ends used for connecting fittings, valves, or
other equipment in tight spaces.
