Amiblu GRP joints and couplings
Amiblu GRP pipe solutions have a proven jointing system that secures the systems work through its whole estimated service life.
Amiblu pipes are typically joined using GRP couplings. All Amiblu GRP pipe solutions have a proven jointing system that secures the systems work through its whole estimated service life. The system also offers solutions for transitions to other materials such as connection to valves or other accessories. Pipes and couplings can be alternatively supplied separately or pre-assembled at one of the female pipe ends.

Field joints for pressure & gravity applications
Laminated field joints are available in uniaxial and biaxial designs. Amiblu provides the necessary instructions or skilled personnel for butt-wrap joining in pressure and non-pressure applications. Technologies developed by Amiblu provide faster and more cost-efficient installations.
Masonry couplings
The masonry coupling is used for connecting pipes to concrete shafts and walls. Masonry couplings are sanded for improved stability in concrete shafts. Masonry couplings can be delivered with pipe ring, and optionally with sealing tape. Lengths can be selected as required in consideration of the pipe joint data.
Mechanical couplings
Amiblu pipes can be joined using mechanical steel couplings such as tangential bolt couplings or axial bolt couplings.
Amiblu flanges
Amiblu manufactures and sells flanges in various designs and according to different standards and requirements. When connecting two GRP flanges, the standard bolt pattern to which flanges are manufactured is EN 1092. Other bolting dimension systems such as according to AWWA, ANSI, DIN, and JIS can be supplied.
