JOINING INSTRUCTIONS - RUBBER RING JOINT (DN80 - DN375)

lplex PVC-U pipes are supplied with the Rieber jointing system. The Rieber seal is fitted at the time of manufacture and subsequently MUST NOT BE REMOVED.

If the ring is tampered with or damaged in any way after leaving the factory then the socket and affected ring must be cut off and scrapped. It is essential to use lplex Standard or lplex Plus bactericidal jointing fluid with the Rubber joint.

CUTTING PIPES PVC-U

pipes can be cut to length on site using either a hand saw or powered cutting disc. Ensure that the cut end is then chamfered with an appropriate field-lathing tool to the correct length. The chamfer and new witness mark should replicate the manufactured dimensions.

CLEANING

Remove all dust and dirt from the pipe spigot and socket paying particular attention to the cleanliness of the fixed ring.

LUBRICATE

Apply lubricant to the spigot, fully covering the circumference up to the witness mark. Ensure the lubricant is also applied to the pipe chamfer.

ASSEMBLY

Insert the leading edge of the spigot into the socket mouth. It is essential that the pipes be aligned in a straight line before attempting to make the joint. A small, longitudinal force applied to the socket end of the pipe is sufficient to insert the spigot into the adjacent pipe socket. For larger diameter pipes requiring a crowbar for jointing, protect the pipe socket with a wooden block.

Care must be taken to ensure that the pipe is not under-inserted as this may result in a leaking joint as the pipe contracts as a result of Poisson's and/or thermal effects. Under-insertion is signified by the witness mark not being pushed up to the end of the socket. Note: When pressurised, Poisson contraction will cause a shortening of the pipes and this might re-expose the witness mark.

This is acceptable. This is generally only a risk with uncontrolled insertion using mechanical equipment like the bucket of a back hoe. If simple insertion past the witness mark has occurred, i.e. pushing it ever so slightly past so the witness mark is now hidden from view, say up to 5mm, there is no significant risk to the performance of the joint. Insertion too far past the witness mark may result in stress to the transition region at the back of the socket to the barrel of the pipe, especially where uncontrolled insertion using mechanical equipment like the bucket of a backhoe or excavator.
