Flowtite GRP pipes and pipe systems

Flowtite filament wound pipes are built as a structural sandwich, using the Flowtite continuous filament winding technology. The basic raw materials used in manufacturing the pipes are resin, glassfibers and silica sand.

 

Flowtite pipe systems are supplied in nominal diameters ranging from DN 80 up to DN 4000, and in various stiffness classes starting at 2500 N/m². Our standard pressure classes go up to 32 bar. The product portfolio includes a wide range of pipes, fittings and spools with additional custom designed solutions.

 

Custom lengths, diameters, pressure and stiffness classes are available on request!

Other joints and couplings

Field joints for pressure & gravity applications
Laminated field joints are available in uniaxial and biaxial designs. Necessary instructions or skilled personnel for butt-wrap joining in pressure and non-pressure applications are provided.

 

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
Flowtite pipes can be joined using mechanical steel couplings such as tangential bolt couplings or axial bolt couplings.

 

Flowtite flanges
Flanges are manufactured 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.

Standard fittings

Flowtite fittings can be produced in both standard and non-standard forms to customer specifications and are available for pressure and non-pressure applications. They are designed based on an extensive research program and patented concepts, have a high stiffness, and are corrosion-free. Amiblu’s researchers have rigorously analysed critical strains in bends, tees, and elbows.

Manholes

 

Flowtite 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 EN 14364  and EN 15383 for underground drainage and sewage.

 

Flowtite 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.

Flowtite standard manhole

Manholes are commonly delivered with berm, ladder, and manhole cover. Further accessories and manhole diameters are available on request.
