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.

Amiblu GRP manholes are made of glassfiber reinforced unsaturated polyester resin. They include a liner with glassfiber reinforcements for an expected higher chemical pollution of municipal wastewater. Shaft and chamber units comply with the requirements of EN14364 for underground drainage and sewage.
Amiblu manholes are custom-tailored to all sorts of operation requirements. In the case of deep installations as required e.g. on landfill sites, the manholes are designed with a bigger wall thickness to increase the structural stability.
Manholes are commonly delivered with berm, ladder, and manhole cover. Further accessories and manhole diameters are available on request. Standard Amiblu manholes meet the requirements of EN 15383.
