Description
The
160mm underground drainage swept bend from Funke is designed to create a smooth near-90° change of direction within compatible 160mm underground drainage pipework. This
160mm single socket bend has an 87.5° nominal angle, making it a practical
160mm 87.5 degree bend for foul-water and surface-water systems. The
Funke drainage bend uses a swept profile to provide a smoother change of direction than a compact tight bend, making it a useful
160mm swept drainage bend for larger drainage runs. The single-socket configuration provides one socketed connection and one plain spigot end, allowing the fitting to be incorporated into compatible 160mm underground drainage pipework, couplers and other fittings.
160mm Underground Drainage Swept Bend
The
160mm underground drainage swept bend is used where a larger underground drainage run needs to turn through approximately 90 degrees. A swept profile creates a more gradual change in direction than a tight-radius bend, which can be useful where maintaining smoother flow through the drainage system is important.
Choosing a 160mm Underground Drainage Swept Bend
Choose the
160mm underground drainage swept bend where compatible 160mm pipework requires a near-90° directional change and a sweeping bend profile is preferred over a compact tight bend. Consider the surrounding drainage layout, available space, pipe fall and future maintenance access before choosing the bend position.
Installing the 160mm Underground Drainage Swept Bend
Before installing the
160mm underground drainage swept bend, make sure the connecting pipe ends and ring-seal socket are clean and free from grit or damage. Use suitable underground drainage lubricant where required and insert the prepared pipe or spigot squarely into the compatible socket without displacing the seal.
160mm Single Socket Bend
This fitting is a
160mm single socket bend, meaning one end contains a socket connection while the opposite end terminates in a plain spigot. The
160mm single socket bend can therefore connect directly to compatible pipe at the socket end while the spigot end can be inserted into another socketed fitting, coupler or pipe.
160mm Single Socket Bend Connection
The single-socket format can provide greater flexibility than a double-socket bend when planning the sequence of fittings within a drainage run. Make sure the spigot end is orientated correctly within the intended drainage layout before bedding and backfilling the system.
160mm 87.5 Degree Bend
The
160mm 87.5 degree bend provides a near-90° directional change while retaining the slight angle traditionally used within drainage systems. A
160mm 87.5 degree bend is commonly described as a 90° drainage bend in trade use, so both descriptions may be encountered when selecting compatible fittings.
Where to Use a 160mm 87.5 Degree Bend
The fitting can be useful where underground pipework needs to turn around structures, change route or connect into another part of the drainage system. For major changes in direction, always make sure the overall drainage design provides suitable inspection and maintenance access where required.
Funke Drainage Bend
This
Funke drainage bend is intended for compatible underground drainage applications using 160mm pipework. Funke manufactures PVC-U underground sewer and drainage systems for foul-water, combined-water and rainwater applications. Its HS system uses unplasticised PVC-U and brown underground drainage fittings. :contentReference[oaicite:1]{index=1}
Funke Drainage Bend for Foul and Surface Water
The
Funke drainage bend can form part of suitable foul-water and surface-water drainage layouts when used with compatible pipe and fittings. Where different manufacturers’ underground drainage components are being combined, check joint and dimensional compatibility before installation.
160mm Swept Drainage Bend
A
160mm swept drainage bend has a more gradual curved profile than a compact tight bend. This smoother directional change can make the fitting particularly useful on larger drainage runs where flow characteristics and future maintenance are considerations.
160mm Swept Drainage Bend vs Tight Bend
Choose a
160mm swept drainage bend where there is sufficient installation space and a smoother change of direction is desirable. A tight bend takes up less space and may be more suitable where the excavation or surrounding structure limits the available room.
PVC-U Underground Drainage
Funke’s current underground HS pipe system is manufactured from unplasticised PVC-U for below-ground drainage and sewerage applications. :contentReference[oaicite:2]{index=2} PVC-U underground drainage fittings provide a lightweight and corrosion-resistant solution for compatible gravity drainage systems.
Foul-Water and Surface-Water Drainage
160mm underground drainage is commonly specified for larger domestic, commercial and groundwork applications where greater carrying capacity is required than smaller drainage systems provide. This swept bend can be incorporated into suitable:
- Foul-water drainage systems
- Surface-water drainage systems
- Rainwater drainage layouts
- Domestic underground drainage
- Commercial drainage installations
- Groundwork and civil drainage projects
- Drainage repairs and alterations
Preparing 160mm Pipe for Installation
If 160mm pipe is cut before installation, make a clean square cut and remove burrs from the end. Chamfer the prepared pipe end where required to help protect the ring seal during insertion. Make sure the socket, seal and pipe surface remain clean throughout assembly.
Bedding and Supporting the Bend
The bend and adjoining pipework should be properly supported in accordance with the drainage installation specification. Avoid leaving the fitting suspended between poorly supported pipe sections, as this can place unnecessary load on the joints once the trench is backfilled.
Inspection and Maintenance Access
A near-90° change of direction can affect access through a drainage run. The surrounding drainage system should therefore include suitable rodding, inspection chamber or maintenance access where required by the installation design. Using a swept bend can help create a smoother route, but it does not remove the need for correctly positioned access points.
