160mm Underground Drainage 90° Double Socket Swept Bend

Description

The 160mm double socket swept bend provides a smooth near-right-angle change of direction within compatible 160mm underground drainage pipework. This 160mm underground drainage bend combines a nominal 90 degree drainage bend angle with the gradual profile of a 160mm swept drainage bend and the convenient connections of a double socket drainage bend for foul-water and surface-water systems. The swept profile creates a smoother change in direction than a compact tight bend, making it particularly useful on larger drainage runs where flow, maintenance and a gradual pipe route are important considerations.

160mm Double Socket Swept Bend

The 160mm double socket swept bend is designed for compatible larger-diameter underground drainage systems where the pipe run needs to turn through approximately 90 degrees. Both ends are socketed, allowing compatible plain-ended 160mm drainage pipe to connect directly into the fitting using push-fit ring-seal joints.

Choosing a 160mm Double Socket Swept Bend

Choose the 160mm double socket swept bend where a substantial directional change is required but a smoother curve is preferred over a compact tight-radius fitting. The swept configuration is particularly useful across larger domestic, commercial and groundwork drainage installations.

160mm Underground Drainage Bend

This 160mm underground drainage bend provides a directional fitting for compatible below-ground gravity drainage pipework. The larger 160mm nominal size is commonly used where increased drainage capacity is required across foul-water, surface-water and general site drainage systems.

Installing a 160mm Underground Drainage Bend

Before installing the 160mm underground drainage bend, make sure both sockets, sealing rings and adjoining pipe ends are clean and free from grit or damage. Use suitable underground drainage lubricant where required and insert prepared pipe ends squarely into the sockets without disturbing the seals.

90 Degree Drainage Bend

The fitting is commonly described as a 90 degree drainage bend because it creates a near-right-angle change in the drainage route. Underground drainage manufacturers may specify this style of fitting at approximately 87° or 87.5°, while merchants and installers commonly refer to it as a 90° bend.

Using a 90 Degree Drainage Bend

When positioning a 90 degree drainage bend, consider the direction of flow and make sure suitable inspection or rodding access is provided elsewhere in the system where required. The bend and adjoining pipe should be correctly supported and bedded before backfilling.

160mm Swept Drainage Bend

The 160mm swept drainage bend uses a more gradual curve than a tight elbow, helping guide the drainage route smoothly around the change in direction. A 160mm swept drainage bend can be preferable where installation space allows a larger fitting and a smoother pipe route is desired.

Benefits of a 160mm Swept Drainage Bend

• Gradual near-90° change in direction
• Smoother profile than a tight bend
• Suitable for larger 160mm drainage runs
• Useful for foul-water drainage
• Suitable for surface-water systems
• Double socket push-fit connection

Double Socket Drainage Bend

The double socket drainage bend has an integral socket at both ends of the fitting. This allows compatible plain-ended 160mm pipe to connect directly into each side without requiring a separate coupler immediately beside the bend.

Double Socket Drainage Bend Installation

Before assembling the double socket drainage bend, check both sealing rings are correctly seated and free from contamination. Keep the pipe ends and socket surfaces clean and use suitable drainage lubricant to protect the ring seals during assembly.

160mm Double Socket Swept Bend Connections

The 160mm double socket swept bend provides two push-fit socket connections for compatible underground drainage pipe. The double-socket arrangement can simplify installation when joining two plain-ended pipe sections at a change in direction.

Swept Bend vs Tight Bend

A tight bend makes the directional change over a relatively short distance. A swept bend uses a broader curve, giving the flow path a more gradual transition through the change in direction. Where installation space is limited, a tight bend may be required. Where space allows, the swept option can provide a smoother route.

Swept Bend vs Long Radius Bend

Both swept and long-radius bends provide a more gradual turn than a compact tight fitting. A long-radius bend generally uses an even larger curve and takes up more installation space. Check the available trench space and surrounding pipe layout before selecting the appropriate fitting.

PVC-U Underground Drainage

This type of bend is manufactured from PVC-U for compatible non-pressure underground drainage systems. PVC-U is widely used for below-ground drainage because it provides a lightweight, corrosion-resistant and straightforward push-fit pipe and fitting system.

EN 1401 Underground Drainage

The equivalent 160mm double-socket swept bend is specified for EN 1401 underground drainage systems. EN 1401 covers PVC-U piping systems for non-pressure underground drainage and sewerage. For further standards information, see the BSI BS EN 1401-1 reference.

Preparing 160mm Drainage Pipe

If pipe needs to be cut before installation, make a clean square cut and remove any burrs from the prepared end. Chamfer the pipe where required before insertion to help prevent damage to the sealing ring.

Bedding and Support

The bend and adjoining underground drainage pipe should be evenly supported using suitable bedding material. Avoid leaving the fitting suspended between unsupported pipe sections, as this can place unnecessary stress on the joints after backfilling.
