grppipsWater is fast depleting natural resource and mankind does not have the luxury of wasting it by transporting in open channels. Many countries have started recycling sewage and waste water and using it for human consumption. Water starved countries are using desalination to convert sea water to potable water.

For conveying water, sewage, waste-water and sea water, the most cost effective solution is Glass fiber Reinforced Plastic (GRP) piping system.


By virtue of its superior material characteristics, GRP pipes have become the ultimate choice replacing steel, DI and Concrete pipes for transporting different process fluids, sea water, raw water and potable water for different underground and aboveground applications.

The single most reason why people go for GRP is the total corrosion resistance that this material offers. Well-engineered GRP pipelines can be totally forgotten after installation for its life period without catholic protection or periodic maintenance and for this reason, GRP pipelines are called as “ZERO-MAINTENANCE PIPING”.

The prime advantages of GRP pipes are:

a) ABSOLUTELY CORROSION FREE: The material is inert to any type of water(sea water, raw water, potable water etc.) and for handling different process fluids, chemicals, acids , bases etc. With suitable GRP material system(resin), pipes can be designed for handling all fluids. M/s SSC will advise customers on this based on their requirement. No coating, gunniting, mortar lining or cathodic protection required with GRP piping.

b) SMOOTH INNER SURFACE: The inner surface of GRP pipe is the best among piping materials, due to which the friction loss is minimum with GRP pipes. Again, unlike steel and other materials, the smooth surface will remain the same throughout its intended service life, as the corrosion is absent in GRP. This gives less power consumption and low pumping cost throughout the pipeline life.

Hazen Williams Coefficient (“C” Value) for GRP is 150 for the purpose of design as per standards; however the tested values are in the range of 160-165. Because of higher ‘C’ Value, frictional losses in GRP Pipes are much less compared to that of conventional pipes. Hence, recurring energy charges and pump cost is lower in GRP Pipes compared to same diameter of other conventional pipes. Alternatively, we can reduce the diameter of GRP Pipes keeping frictional losses same as in case of conventional pipes.

c) LONGER LIFE: GRP pipes are designed for 50 years of life for normal applications. For Offshore applications, the design life is 20 years.

d) HIGH STRENGTH TO WEIGHT RATIO: The high-strength to weight ratio of this material offers the advantage of weight reduction and due to this, it is easy to handle & transport and this aids faster installation. It is light in weight, 1/5th of Steel, 1 /8th of CI and 1/10th of PSC for the same pressure rating and strength criterion.

e) EXCELLENT JOINT TIGHTNESS: Different joints like bell & spigot with rubber seal, coupler, butt & wrap flanged joints are available. Engineered joints totally eliminate ex-filtration / infiltration.

f) RESISTANCE TO SURGE PRESSURE: The water hammer in GRP pipe is less due to elasticity of GRP pipe. GRP pipes can withstand pressure up to 1.4 times of its pressure class in case of surge, which is higher than conventional pipes.

g) FREE OF MAINTENANCE: GRP pipelines are virtually maintenance free after installation. In case of repair, it can be repaired at site easily without any necessity of heavy equipments.


SSC’s radical design methodology, specific for composite materials and newer manufacturing technology combined with the economy of large-scale production have ensured that GRP Pipes are an economic alternative to conventional piping materials for water, sewage and sea-water application. If life-cycle and performance costs are compared, GRP Pipes will be 2 to 3 times cost effective than other piping system due to its superior properties.

Apart form the supply of GRP pipes to the process industries, SSC has converted many international water and sewage piping projects to GRP Piping systems. . SSC has completed the longest GRP piping project, the 27.5 miles (44.0 km.), 32 inch (800 mm) diameter, 175 psi (12 bar) effluent disposal pipeline. It has also designed, manufactured and installed the largest GRP Pressure pipe, 72 inches (1800mm), 75 psi (5 bar) and the highest pressure pipes, 600 psi (40 bar), 10 inch (250mm) diameter.

In addition, SSC establishes project specific manufacturing facilities on the basis of project economics and logistics. In fact, SSC is the pioneer in the conceptualization and adoption of project-specific manufacturing facilities in order to bring down the transportation cost of large diameter pipes. This scheme is being successfully adopted by SSC for large projects.

In addition to the supply GRP piping, SSC provides total engineering including the selection of composite material system for handling different corrosive media, installation and/or installation supervision. Our service covers the entire process of Design, Engineering, Manufacturing, Logistics and Installation.


SSC designs and manufactures pipes for a wide range of applications:

Process pipes: These pipes are predominantly used for their corrosion resistant properties. These have been used for oveor 50 years in the chemical process industries like chloro-alkali, water treatment and paper bleaching. These pipes normally have high-end corrosion resistant resin system (Vinyl ester) with corrosion barrier thickness of  1.2 mm to 2.5 mm.

Water & Sewage pipes: Cost effective GRP pipes are replacing traditional materials like Ductile Iron, Pre-stressed Cement Concrete, Steel with epoxy coating / cement mortar lining, PV C and HDPE, which have been used for this application. GRP pipes offer a lower pumping cost and longer life due to its superior properties.

Fire Water piping: GRP pipes offer a better alternative to steel pipes for fire water lines. GRP pipes do not need wrapping & coating / cement mortar lining, PVC and HDPE, which have been used for this application. GRP pipes offer a lower pumping cost and longer life due to its superior properties.

Oil & Gas pipes: ASME Section 31.3 allows GRP pipes for all gas and oil pipelines.. Slowly, oil companies are accepting its use in produce water, process water and effluent water applications in on-shore oil fields and off-shore platforms.

Power Plant Piping: GRP piping are most suitable for sea water intake, sweet water intake, cooling water lines, DM water pipes, acid lines, condensate lines etc.
