Applications of Pipework
Methods of Joining Pipe
Butt-Welded Systems Fittings
These are used for making 45º or 90º changes in the direction of the pipe run. Normally used are “long radius”, in which the centre line radius of curvature is equal to 1 1/2 times the nominal pipe size (MPS). Also available are “short radius” in which the centre line radius of curvature is equal to the NI’S.
Return Pipe Bend
A return makes a 180 change in direction and is used in the construction of heating coils, etc.
Socket-Welded and Screwed Systems
The raised face is the most common type of flange, in which the gasket covers only the raised faces.
