Rigid socketed pipe AKS Rlm 20 (model 444180) in black is a factory-made, non-flexible plumbing component intended for use in drainage and waste systems. The pipe is supplied as a plain length with an integrated socket to permit push-fit or solvent-weld joints, providing a consistent bore and a stable conduit for fluids in domestic and light commercial installations where a durable, straight run is required.
Advantages
This AKS Rlm 20 rigid socketed pipe offers dimensional stability and resistance to deformation under normal operating conditions, which supports accurate alignment and leak-minimising joints. The integrated socket simplifies assembly, reducing the need for additional fittings during installation. Its black finish is suitable for concealed installations and helps mask soiling in service environments.
Suitable for
- Drainage and soil stacks in domestic sanitary systems
- Waste water runs and straight horizontal or vertical risers
- Repair and replacement of damaged sections in light commercial plumbing
- Projects requiring solvent-weld or push-fit connections with compatible fittings
When it may not be suitable
The rigid nature of this pipe means it is not appropriate where flexibility or bending around obstacles is required. It should not be used for high-pressure service, potable water under pressure, or applications requiring certified pressure pipe unless specified by system standards. Compatibility with existing fittings should be confirmed before purchase.
Key specifications
- Material: manufactured polymer suitable for drainage and waste systems
- Connection type: socketed end for push-fit or solvent-weld jointing
- Design: rigid, non-flexible straight pipe
- Color: black
- Typical applications: domestic and light commercial drainage and waste conduits
How to use
Measure and cut the pipe to the required length using an appropriate pipe cutter or saw, ensuring square, burr-free ends. Prepare the socket and spigot surfaces according to the chosen joint method: clean and apply solvent cement for solvent-weld connections or install a compatible push-fit fitting per manufacturer instructions. Assemble joints with correct insertion depth and alignment, allow chemical joints to cure for the recommended time, and support the pipe at regular intervals to prevent sagging.
What to consider before purchase
- Confirm diameter and wall thickness are compatible with your existing system and fittings
- Verify whether push-fit or solvent-weld jointing is required for your application
- Ensure material suitability for the fluids and temperatures expected in service
- Check local building codes and standards for permitted use in your installation
Usage recommendations
For reliable performance, use compatible AKS or standard drainage fittings, follow solvent cement manufacturer instructions for joint preparation and curing, and install supports at intervals recommended for rigid drainage pipe to maintain correct slope and prevent deflection.
