JOINTING
Different jointing methods as follows can be used for jointing Cosmoplast GRP pipes and fittings.

Double Bell Coupling Joints with two rubber rings:

 

In order to ensure that the joints are leak proof, Cosmoplast manufactures double bell couplings with two rubber rings to join the pipes and fittings.

Laminated Joints:

 

These are permanent joints, which consist of a laminate of glass mats and tissues with resin.

Predominantly used directly at the jobsite, this type of joint guarantees a safe and long-lasting connection that accommodates all axial strengths.For the laminated joint, plain-ended pipes and fittings must be used. This joint consists of a glass fiber impregnated with resin, which is laminated according to a specified width and thickness.

Flanged Joints:

The safety of the joint using a flange is the same as any other jointing method and also allows for the dismantling of the installation after use. Flanges are also a good solution for connections with other pipe materials, valves and accessories and are available as fixed and loose flanges. The two types of flange connections available are:

•Socket / Spigot Flexible Flange Joint

•Stub End and Loose Flange Joint
