Jointing Procedure – Spigot and Socket Joint
Forsheda 140 Lamell Sliding Rubber seal permits installation with very little force as there is lubricant enclosed within the seals sliding layer, thus there is no friction between concrete pipe and rubber seal. The sliding layer, when in final position locates itself in the gap between spigot and socket and then prevents concrete to concrete contact if pipe is deflected. Click here to view larger diagram
Installation
- Fit the seal onto spigot as shown on Fig. 1. and Video Below
- Centre the spigot in the socket as Fig. 1.
- Slide the pipes together and the lubricated flap will move over top of the compressed rubber seal as Fig. 2 and finish as shown on Fig. 3.
The relevant pipe diameter is stamped on each rubber ring. Rubber rings should be carefully stored and protected from sunlight, oils, greases and heat, if rings have been tied they should be separated a few days before using in order to eliminate minor impressions the tying may have caused.
Joint rings are normally Styrene Butadiene Rubber (SBR) complying with BS 2494. Nitrile and Ethylene Propylene Rubber (EPDM) can be supplied if specifically ordered to meet special conditions, but are not normally available from stock.

Laying Pipes
After ensuring that you are using the correct bedding, Diameter and class of pipe as specified and that jointing rings are compatible with the pipes to be laid, then the following procedure should be followed:
Installation Instructions
Mechanical plant should not be used to push pipes down to their correct level.
When jointing pipes the last pipe laid sometimes has a tendency to reassert therefore it should be propped and checked before laying commences.
Tracey Concrete’s Spigot and Socket pipes are ideal for surface storm water and foul water systems. Our pipes have been used for countless miles of roadways and drainage projects throughout Ireland and the UK over the past 20 Years. We also manufacture an efficient surface water attenuation system or SuDS systems.
