Connecting spigot to clay and concrete pipes

Sewage pipe systems are high-value assets of a value which should be maintained for a long time. Increasing demands on the connecting pipes require materials which meet these criteria. HD-PE sewage pipes have been fused for many years with the FRIAFIT HD-PE sewage system tightly, friction-locked and root-proof.

Area of application

The FRIAFIT connecting spigot ASA-MULTI is used to connect fused HD-PE house service lines or side branches to clay or concrete pipes. The FRIAFIT connecting spigot ASA-MULTI facilitates an economic connection for new pipes as well as refurbishment – without separating or completely exposing the main sewer. FRIAFIT connecting spigot ASA-MULTI: Space-saving assembly – easy processing – short as

sembly time.

Notes on processing

Tapping of the clay or concrete pipe is made with common core drills – core bit with standardised drilling diameter d = 172 mm. The FRIAFIT connecting spigot ASA-MULTI is assembled by mechanical clamping with elastomer seal. The spigot is directly fused with the connecting pipe using a FRIAFIT coupler AM or a FRIAFIT bend ABM: Leak-proof, friction-locked and root-proof (see also “Assembly instructions for the FRIAFIT sewage system”).

Good reasons for the FRIAFIT connecting spigot ASA-MULTI

Direct transition from main sewer made of concrete/clay to fused HD-PE connecting pipe:

• Leak-proof, friction-locked, root-proof
• Safe and quick installation thanks to easy handling
• Elastomer seal is only required for the interface main sewer/connection
• Economic production of house service connections and road drains for new buildings and refurbishment
• Little space required thanks to compact design
• Use of common core bits
• Large tolerance range for core drilling
• No penetration of the connecting pipes into the main sewer
• Level when using SDR 17/17.6 connecting pipes, no drain obstructions
• The type with bright coat facilitates an optimal view during camera inspection.
