160mm Underground Drainage 90° Single Socket Long Radius Bend

Description

The 160mm 90 degree long radius bend is designed to create a smooth change of direction within compatible 160mm underground drainage pipework. This 160mm long radius drainage bend combines a sweeping profile with a 160mm single socket drainage bend connection, providing a practical 90 degree underground drainage bend and 160mm swept drainage bend for larger foul-water and surface-water systems. The long-radius profile creates a more gradual directional change than a compact tight bend, making it particularly useful where smoother flow and easier future maintenance are important.

160mm 90 Degree Long Radius Bend

The 160mm 90 degree long radius bend is used where a compatible 160mm underground drainage run needs to turn through approximately 90 degrees without using a short-radius fitting. The extended curve provides a smoother path through the bend and can be particularly useful on larger drainage runs, commercial projects and groundwork installations.

Choosing a 160mm 90 Degree Long Radius Bend

Choose the 160mm 90 degree long radius bend where the drainage layout requires a substantial change of direction but a gradual sweeping profile is preferred over a tight elbow. It is especially useful where flow performance, rodding access and maintainability are considerations within the drainage design.

160mm Long Radius Drainage Bend

A 160mm long radius drainage bend creates a larger sweeping arc than a conventional compact bend. This helps guide foul water or surface water around the change in direction with a smoother transition through the fitting.

160mm Long Radius Drainage Bend Applications

The 160mm long radius drainage bend can be used within suitable applications including:

• 160mm underground foul-water drainage
• Surface-water drainage systems
• Rainwater drainage layouts
• Commercial groundworks
• Larger domestic drainage systems
• Main underground drainage runs
• Drainage repairs and alterations

160mm Single Socket Drainage Bend

The 160mm single socket drainage bend has one integral socket connection and one plain spigot end. This allows one side to accept compatible plain-ended pipe while the spigot end can connect into a suitable 160mm socket, coupler or other fitting.

Installing a 160mm Single Socket Drainage Bend

Before fitting the 160mm single socket drainage bend, make sure the socket, ring seal and adjoining pipe ends are clean and free from grit or damage. Use suitable underground drainage lubricant where required and insert the prepared spigot squarely into the socket without disturbing the sealing ring.

90 Degree Underground Drainage Bend

A 90 degree underground drainage bend allows the pipe route to make a major directional change where the site layout requires it. The long-radius design makes this fitting different from a compact 90° tight bend by spreading the direction change over a larger curve.

Using a 90 Degree Underground Drainage Bend

When installing a 90 degree underground drainage bend, consider the direction of flow and make sure suitable inspection or rodding access is available within the overall system where required. The fitting should be properly supported and bedded so surrounding pipework does not place unnecessary stress on the socket connection.

160mm Swept Drainage Bend

The long-radius profile gives the fitting the characteristics of a 160mm swept drainage bend, creating a more gradual flow path than a short tight-radius elbow. A 160mm swept drainage bend can be useful where a smoother change of direction is preferred on larger gravity drainage systems.

Benefits of a 160mm Swept Drainage Bend

• Gradual directional change
• Long-radius flow path
• Suitable for larger 160mm drainage runs
• Single-socket installation format
• Useful where maintenance access is important
• Suitable for compatible foul-water and surface-water systems

Long Radius Bend vs Tight Bend

A tight bend creates the directional change over a much shorter distance. A long-radius bend uses a larger sweeping curve, making it preferable where installation space allows and a more gradual change in flow direction is required. If installation space is restricted, a compact tight bend may be more suitable.

Long Radius Bend vs Standard Swept Bend

Both fittings provide a smoother turn than a tight elbow, but the long-radius version typically spreads the change of direction over a larger overall fitting length. Always check the available installation space before choosing between bend types.

Single Socket Connection

The fitting uses a single socket and plain spigot arrangement. The socket provides a push-fit ring-seal connection to compatible 160mm pipe, while the plain end can insert into another suitable drainage socket.

PVC-U Underground Drainage

Comparable 160mm long-radius drainage bends are manufactured from PVC-U for non-pressure underground drainage and sewerage systems. PVC-U is widely used below ground because it provides a lightweight and corrosion-resistant drainage system suitable for compatible foul-water and surface-water installations.

BS EN 1401-1 Underground Drainage

Comparable 160mm long-radius single-socket bends are manufactured to EN 1401-1 for PVC-U non-pressure underground drainage and sewerage systems. BS EN 1401-1 covers PVC-U pipes, fittings and systems used in buried non-pressure drainage and sewerage applications. For further standards information, see the BSI BS EN 1401-1 reference.

Preparing 160mm Drainage Pipe

If drainage pipe needs to be cut before installation, make a clean square cut and remove any burrs from the prepared end. Chamfer the edge where required to help protect the socket seal during assembly and make sure all jointing surfaces remain clean.

Bedding and Support

The long-radius bend and adjoining pipework should be evenly supported on suitable bedding. Avoid leaving the fitting suspended between unsupported pipe sections, as movement after backfilling can place unnecessary load on the joints.

160mm 90 Degree Long Radius Bend Applications

The 160mm 90 degree long radius bend is suitable for compatible applications including:

• 160mm underground drainage
• Foul-water systems
• Surface-water drainage
