Description
The
160mm 30 degree double socket bend is designed to create a controlled change of direction within compatible 160mm underground drainage pipework. This
160mm underground drainage bend combines a useful
30 degree drainage bend angle with a convenient
double socket drainage bend configuration, providing a durable
PVC-U underground drainage bend for foul-water and surface-water systems. The 30° angle provides a more noticeable directional change than a 15° bend while remaining gentler than a 45° or near-90° fitting, making it useful for adjusting larger drainage runs without introducing an unnecessarily sharp turn.
160mm 30 Degree Double Socket Bend
The
160mm 30 degree double socket bend allows installers to alter the route of a compatible 160mm drainage run while maintaining a gradual flow path. Both ends are socketed, allowing compatible plain-ended 160mm underground drainage pipe to connect directly into the fitting using push-fit ring-seal joints.
Choosing a 160mm 30 Degree Double Socket Bend
Choose the
160mm 30 degree double socket bend where the drainage run needs a moderate 30° change of direction. This angle is useful for realigning pipework, changing trench direction or routing drainage around site obstructions without using a sharper bend than necessary.
160mm Underground Drainage Bend
This
160mm underground drainage bend is suitable for compatible larger-diameter gravity drainage installations. The 160mm size is commonly used on larger domestic, commercial and groundwork drainage systems where increased carrying capacity is required.
Installing a 160mm Underground Drainage Bend
Before installing the
160mm underground drainage bend, make sure both sockets, seals and pipe ends are clean and free from grit, damage and loose debris. Use suitable underground drainage lubricant where required and insert the prepared pipe squarely into each socket without displacing the ring seal.
30 Degree Drainage Bend
A
30 degree drainage bend provides a moderate change of direction within an underground drainage run. The
30 degree drainage bend sits between the shallow adjustment of a 15° fitting and the stronger directional change produced by a 45° bend.
Where to Use a 30 Degree Drainage Bend
A
30 degree drainage bend can be useful for:
- Changing the direction of a 160mm drainage run
- Correcting moderate pipe alignment differences
- Routing pipework around site obstructions
- Foul-water underground drainage
- Surface-water drainage
- Rainwater drainage systems
- Domestic and commercial groundworks
Double Socket Drainage Bend
The fitting uses a
double socket drainage bend configuration, meaning both ends contain socket connections for compatible plain-ended pipe. A
double socket drainage bend can simplify installation because separate couplers are not normally required immediately either side of the bend.
Double Socket Drainage Bend Connections
Each socket uses a push-fit ring-seal connection. Check that both seals are correctly seated before installation and keep all jointing surfaces clean throughout assembly. Pipe should enter each socket squarely and should not be forced into alignment through the fitting.
PVC-U Underground Drainage Bend
This fitting is a
PVC-U underground drainage bend intended for compatible non-pressure gravity drainage systems. PVC-U is widely used for underground drainage because it provides a lightweight, corrosion-resistant and durable pipe and fitting system.
PVC-U Underground Drainage Bend Applications
The
PVC-U underground drainage bend can form part of suitable foul-water, surface-water and rainwater drainage layouts where 160mm pipework is specified.
BS EN 1401 Underground Drainage
This type of 160mm PVC-U underground drainage fitting is used within systems manufactured to BS EN 1401 for non-pressure underground drainage and sewerage. Comparable 160mm 30° double-socket bends are specifically sold for EN 1401-compatible underground drainage systems. :contentReference[oaicite:1]{index=1}
30° Bend vs 15° Bend
A 30° bend creates twice the nominal directional change of a 15° fitting. Choose the 30° option where a more noticeable change in direction is required, while a 15° bend is better suited to smaller alignment corrections.
30° Bend vs 45° Bend
A 45° bend creates a sharper directional change than a 30° fitting. Where the drainage route can be achieved with the shallower angle, a 30° bend provides a more gradual transition.
Preparing 160mm Drainage Pipe
If drainage pipe needs to be cut before installation, make a clean square cut and remove burrs from the pipe end. Chamfer the prepared end where required to help protect the ring seal during insertion and keep the pipe and socket clean before assembly.
Bedding and Support
The bend and adjoining 160mm pipework should be correctly bedded and supported within the trench. Avoid leaving the fitting suspended between unsupported pipe sections, as this can place unnecessary stress on the socket joints after backfilling.
Foul-Water Drainage
This fitting can form part of compatible foul-water gravity drainage systems where 160mm underground drainage pipe is required. The complete installation should maintain appropriate pipe falls and include suitable inspection and maintenance access.
Surface-Water Drainage
The bend can also be incorporated into compatible surface-water and rainwater drainage systems where a controlled 30° change of direction is required.
