We supply a wide range of Buttweld Fittings. Widely used in Oil, Gas, Filtration, Refrigeration, Refining, Petrochemical and Offshore Industries.
Buttweld Fittings are used in a piping system to change a direction or function, which is mechanically joined to the system. Probably the simplest way to achieve this would be to bend the pipe in the direction required, but this process will stretch and thin the outer wall of the pipe whilst thickening and wrinkling the inner wall of the pipe. This results in flow resistance and accelerated wall erosion.
A second method sometimes used is a mitred joint, where steel Buttweld Fittings are cut to the correct angle and welded together to achieve the desired change. Whilst the cross-section area and wall thickness are maintained a great deal of efficiency is lost due to friction and turbulence resulting from the severe change in direction; for example a single-mitred bend offers about six times the resistance of a swept elbow.
