| SPIGOT & SOCKET PIPES - JOINTING AND LAYING |
|
Jointing Procedure
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 rubberseal.
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.

Installation
- Fit the seal onto spigot as shown on Fig. 1.
- Centre the spigot in the socket as Fig. 1.

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:
