Backdrop Junction

Junctions and Bends are manufactured in accordance with I.S.6. They have the same wall thickness and internal diameters as the pipes with which they are to be used. Junctions are manufactured from components produced by the vertically cast process, but the whole of the branch, the main incorporating the branch, and bends, should be encased in a concrete surround designed to withstand external loads.
