Short Radius Drainage Bend (Pipe-Elbow)

Short radius drainage bend is a compact uPVC elbow that redirects underground foul or surface water flows through tight directional changes. Built from rigid PVC-U for stability and chemical resistance, this bend integrates into standard drainage networks to maintain uninterrupted hydraulic performance in constrained installation zones. Smooth internal bore ensures efficient gravity flow and self-cleansing velocity under typical waste volumes. Suitable for both 110 mm and 160 mm drainage systems, these bends allow efficient pipe routing where space or trench alignment requires rapid change of direction.

Single Socket:

Single socket short radius bends offer one socketed end and one spigot end. This configuration simplifies connection to plain-ended drainage pipes, while the other end plugs into an existing socket or coupling. Available angles typically include 15°, 30°, 45° and 87.5°, covering common routing needs from gentle deflection to sharp directional changes. Ideal for retrofit or repair work where one end connects directly and the other fits into an existing socket.

Double Socket:

Double socket short radius bends provide sockets at both ends for push-fit connection of two plain-ended pipes or fittings. This variant supports the same range of angles - 15°, 30°, 45° and 87.5° - enabling fully socketed joints without additional couplers or adaptors. Double socket bends are particularly useful in new-build drainage installations, enabling watertight connections and reducing site labour by eliminating solvent welding or mechanical joins.

Installation Guide:

• Excavate trench and bed base to required gradient (typically 1:40–1:80 for foul drainage).

• Cut and deburr pipe ends, chamfer spigot as per pipe manufacturer's guidance.

• For double-socket bend: lubricate socket seal and insert first pipe fully.

• For single-socket bend: lubricate socket, insert plain-ended pipe; join the other end into existing socket or coupling.

• Align bend to maintain correct flow direction and ensure no kinks or stress at joints.

• Backfill with granular material in layers to support pipe and maintain joint integrity.

• Perform flow test to verify free discharge and check for leaks.
