Piping System & SolutionsKemrock manufactures GRE/GRP Pipes using the filament winding process. Pipes of diameter 25mm to 3000mm and a full range of flanges & fittings are manufactured in ‘state-of-art’ CFW/ HW machines. It is amongst the very few manufacturers in the world who produce their own thermosetting resins for manufacturing Pipes.

GRP Pipes

Kemrock Corrosion resistant Fibre Glass Reinforced Polymer Composite Pipes meet the demanding needs of industry to transport corrosive and non-corrosive fluids for various applications including Oil and Gas, Petrochemical, Power Generation, Desalination, Potable Water, Municipal and General Industries.

Kemrock composite pipes are manufactured with Polyester, Vinylester and Epoxy Resins using either the dual helical filament winding (discontinuous) or the continuous advancing mandrel filament winding technique. In our purpose built 100,000 square feet, we employ both techniques, manufacturing pipes of different specifications up to 3000mm in diameter. Kemrock composite pipes provide superior corrosion resistance, high mechanical and physical properties as well as the ease of handling, transportation and installation when compared to traditional materials.

Kemrock is among the very few composite pipe manufacturers in the world who also produce their own thermosetting resins such as Polyester, Vinyl Ester and Epoxy Resins in-house thereby ensuring uninterrupted and consistent quality of resin supply to the plant, to meet the most challenging contractual commitments.

Kemrock GRP Pipes are manufactured and tested in accordance with international and domestic standards such as AWWA, ASTM, BS and BIS to verify the longterm performance, visual, dimensional characteristics as well as their physical and mechanical properties.

Comparison of GRP Pipes with Ductile Iron, Mild Steel & Hdpe Pipes

Sr No. Properties GRP Pipes Ductile Iron Mild Steel HDPE
1. Corrosion Resistance High against all kind
of fluids
Moderate with internal mortar lining External wrapping and Cathodic Protection required Satisfactory
2. Maintenance Minimum mainten-
ance required
Periodic inspection required Periodic inspection required Repair not possible
3. Design Life 50 years 30 years 30 years 50 years
4. Friction Factor(Hazen Williams Coefficient “c” Value) 150 140 140 150
5. Thickness Optimized by Design Standard Dimensions Optimized by Design Standard Dimensions
6. Surge Pressure Best in handling
Protection device needed Protection device needed Reasonably good
7. Weight Light Weight 5-6 times heavier than GRP 3-4 times heavier than GRP Weight is higher than GRP due to higher thickness
