CC-GRP Pipes The CC-GRP Pipe System is composed of a thermo set composite material. The production process a special combination of raw materials supplied by selected partners is used. The main Raw Materials are Glass Fiber, Resin, Reinforcing Materials and EPDM. The product is manufactured by means of the Centrifugal Casting Process, which allows for a smooth, uniform and extremely abrasion-resistant special inner layer. Pipe and Fitting    CC-GRP Pipe  Coupling Bend Tee Short Pipe Process The process for produces CC- GRP Pipe Systems is the centrifugal casting a product with unique features. Patented by HOBAS the centrifugal casting process produces compact pipes with programmable characteristics. Therefore, the pipes can provide individual solutions. The properties of which convince worldwide. Glass Fiber Every Pipe has to meet structural, mechanical and chemical requirements according to its type and to comply with national standards. The major reinforcing material used for the Pipes to achieve the recommended mechanical properties in the axial and circumferential direction is glass fiber. There are some layers in the wall structure of a  Pipe in which the fibers are the main component and responsible for the excellent mechanical properties of every  Pipe. Resin Very detailed specifications have been compiled for Unsaturated Polyesters intended for use in pipe production by centrifugal casting in order to ensure the process ability (gel, exothermic and curing times, viscosity), the compound performance (elastic modulus, tensile and bending strength/strain, glass transition) and the service performance of the pipe during its life cycle (chemical resistance, molecular weight, acid number, heat deflection temperature).   Reinforcing Materials Generally it is possible to mix unsaturated polyester resins with various reinforcing materials of natural or artificial origin. These reinforcing materials are used to achieve certain mechanical properties (stiffness) and also to reduce resin consumption during production. Typical reinforcing types used in the Process are calcium carbonate CaCO³ powders, such as limestone, marble or dolomite. Limestone is a semi-crystalline material with an age of approximately 110 to 150 million years, whereas marble is highly crystalline dating back some 300 to 500 million years. Both materials are of completely biogenetic origin and are to be found nearly all over the world. Typical sand types for the process are, similar to filler carbonate or quartz (Si0²) aggregates with a grain size up to 1 mm. Rubber Filling the gap between the pipe and joint requires a material which can be deformed reversibly in order to ensure tightness of the pipeline, even if there is relative movement between the pipe and joint. The material sought must be water-resistant and also resistant to a wide variety of chemicals which may be transported together with the water. For that purpose an EPDM (ethylene propylene dine polymer) is the perfect choice. Its excellent ability to restore its shape after having been stressed and relieved and its good chemical resistance are of major importance when being used for sealing profiles.
