For FRP pipe jointing restrained type and unrestrained type joint system.
Resistant to acids, alkalis, salts, organic solvents and water, sewage and other chemical mediators of long-term corrosion. Resistance to ozone aging, the storage life of up to 50 years, consistent with the life of the pipeline. Corrosion resistance and long service life.

EPDM O-Ring 

This type of joints is suitable for low to medium pressure, underground applications and provide for rapid assembly and disassembly.
Achieved by methods of one or more rubber O-rings inserted into grooves in the male pipe end. The axial load is supported by a cylindrical nylon locking key, inserted through a tangential hole in the socket wall, into preformed tangential grooves in the both end of the pipe.
The pressure of the joint can be increased by the use of more than one key.

Type:

• Bell and Spigot joint by double ‘O’ ring
• Bell and Spigot joint by double ‘O’ ring with locking key
