Description
The
160mm 45 degree long radius bend provides a gradual change of direction within compatible 160mm underground drainage systems. This
160mm long radius drainage bend combines a sweeping 45° profile with a
160mm single socket 45 bend connection, creating a practical
45 degree underground drainage bend and durable
160mm PVC-U long radius bend for foul-water and surface-water pipework. The extended curve creates a smoother directional transition than a compact short-radius bend, making this fitting particularly useful on larger drainage runs where installation space allows a more gradual change in direction.
160mm 45 Degree Long Radius Bend
The
160mm 45 degree long radius bend is designed for installations where a 160mm underground drainage run needs to change direction by approximately 45 degrees. Its long-radius profile spreads the change of direction across a larger curve than a standard compact bend.
Choosing a 160mm 45 Degree Long Radius Bend
Choose the
160mm 45 degree long radius bend where a gradual 45° change in direction is preferred over a tighter fitting. The smoother curve can be particularly useful on larger foul-water and surface-water drainage runs, as well as commercial and groundwork installations.
160mm Long Radius Drainage Bend
A
160mm long radius drainage bend provides a more sweeping route through the directional change than a short-radius elbow. The larger curve can make the drainage route easier to follow and maintain where sufficient installation space is available.
160mm Long Radius Drainage Bend Applications
The
160mm long radius drainage bend can be used for compatible applications including:
- 160mm underground drainage systems
- Foul-water drainage runs
- Surface-water drainage
- Rainwater drainage
- Commercial groundworks
- Larger domestic drainage systems
- Drainage alterations and extensions
- Gradual changes in pipe direction
160mm Single Socket 45 Bend
The
160mm single socket 45 bend uses one integral socket connection and one plain spigot end. The socket accepts compatible plain-ended 160mm drainage pipe, while the spigot end can be inserted into another suitable socket, coupler or fitting.
Installing a 160mm Single Socket 45 Bend
Before installing the
160mm single socket 45 bend, make sure the socket, sealing ring and adjoining pipe ends are clean and free from grit or damage. Use suitable underground drainage lubricant where required and insert the prepared pipe squarely without displacing the ring seal.
45 Degree Underground Drainage Bend
A
45 degree underground drainage bend provides a useful intermediate directional change between shallower 15° or 30° fittings and a near-90° bend. The 45° angle is commonly used where a drainage route needs a noticeable but controlled change of direction.
Using a 45 Degree Underground Drainage Bend
When positioning a
45 degree underground drainage bend, consider the direction of flow, pipe fall and available installation space. The bend and surrounding pipework should be correctly supported and bedded to prevent unnecessary loading on the socket connections.
160mm PVC-U Long Radius Bend
This type of
160mm PVC-U long radius bend is intended for compatible non-pressure underground drainage systems. PVC-U is widely used for underground drainage because it provides a lightweight, corrosion-resistant and straightforward push-fit pipe and fitting system.
160mm PVC-U Long Radius Bend Applications
The
160mm PVC-U long radius bend is suitable for compatible gravity drainage systems including foul-water, surface-water and rainwater installations.
Long Radius Bend vs Standard 45° Bend
A standard 45° bend changes direction over a relatively compact fitting length. A long-radius bend uses a larger sweeping curve, providing a more gradual route through the same nominal change in direction. Choose the long-radius version where the drainage design and available installation space favour the smoother profile.
Long Radius Bend vs Tight Bend
A tight bend provides a compact directional change where space is restricted. The long-radius alternative requires more room but creates a smoother curve through the drainage run.
Single Socket Connection
The fitting has one push-fit socket and one plain spigot end. This connection arrangement allows the bend to integrate directly with compatible 160mm underground drainage pipe and fittings without requiring sockets at both ends.
Push-Fit Ring Seal Joint
The socket uses a ring-seal connection for straightforward push-fit assembly. Keep the socket, seal and pipe surface clean during installation and use suitable drainage lubricant where required.
EN 1401 Underground Drainage
The exact equivalent fitting is specified for EN 1401 underground drainage systems. EN 1401 covers PVC-U piping systems for non-pressure underground drainage and sewerage. For further information, see the
BSI BS EN 1401-1 standard reference.
Preparing 160mm Drainage Pipe
If pipe needs to be cut before installation, make a clean square cut and remove burrs from the prepared end. Chamfer the edge where required before insertion to help protect the ring seal and make sure the jointing surfaces remain clean.
Bedding and Support
The bend and adjoining pipework should be evenly supported using suitable underground drainage bedding. Avoid leaving the fitting suspended between unsupported pipe sections before backfilling.
Foul-Water and Surface-Water Drainage
The
160mm 45 degree long radius bend can form part of compatible foul-water and surface-water gravity drainage installations. Correct falls, bedding, pipe support and suitable maintenance access should be maintained throughout the complete drainage system.
