Hobas CC-GRP pipes and pipe systems

Hobas CC-GRP pipes are made of chopped glass fiber, thermosetting resins (e.g. unsaturated polyesters or vinyl ester resins), minerals, and silica sand. The pipes are circular with an even outer diameter.

 

Hobas pipe systems are supplied in nominal diameters ranging from DN 200 up to DN 3600. Our standard pressure classes go up to 25 bar and stiffness classes to 30000 N/m². The product portfolio includes a wide range of pipes, fittings and spools with additional custom designed solutions.

 

Hobas pipes are easy to install. Installation methods include open trench, jacking, relining, above ground, as well as underwater.

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

 

Hobas 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

Hobas 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.

Manholes

 

Hobas 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 for underground drainage and sewage.

 

Hobas 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.
