Glass Reinforced (FRP,GRP,GRV,RPMP) Pipes & GRP Manholes

GRP pipes are manufactured using the process of Continuous Filament Winding (CFW). Famous for being lightweight, ease to install and deterioration resistance, our GRP pipes are rust proof and hence do not require periodic maintenance. Their resistance to water and sewage systems acidic environment are another advantage. Our GRP pipes are mainly used for transporting drinking water, sewage drainage and seawater, in addition to desalination water, chemical and industrial residues, fire-fighting systems cooling systems and irrigation. GRP pipes and fittings are produced in diameters ranging from 25mm to 4000mm in addition to manholes with different diameters range as per customer request.

GRP products are designed for use in normal to aggressive environments with wide temperature range. The following are standard applications for GRP products:

  • Raw and potable water
  • Sea and brine water
  • Sanitary and industrial sewer
  • Oily sewer
  • Chemical
  • Fire fighting
  • Cooling water
  • District Cooling

Consult Advanced Piping Solutions for pipes intended to handle heavy industrial wastes, toxic chemicals, hazardous fluids or those for above ground or higher temperature services.


Advanced Piping Solutions manufactures Glass-Reinforced Polyester (GRP) Pipes and fittings using the Continuous Filament Winding (CFW) process. GRP products are superior to conventional piping materials due to the following
basic features and benefit:

Corrosion Resistant
GRP pipes are designed for long effective service life without any type of protection such as lining, coating, cathodic protection or any other form of corrosion protection which is required for traditional material.
This enables the GRP pipe end users to achieve low maintenance costs.

Light weight and Long Pipe Sections
GRP pipe is one fourth weight of DI pipe and one tenth weight of Concrete pipe, reducing transport and handling equipment costs. The standard pipe length is 12 meters and can be 18 meters reducing number of joints thereby reducing the installation time and cost.

Extremely Smooth Pipe Interior Surface
GRP pipe have very smooth bore which reduces fluid flow frictional losses thereby reducing pumping cost And this also helps in minimizing slime build up reducing total operational costs.

Flexible & Leak Tight Coupling Joint
GRP flexible joint with elastomeric rubber rings allows pipe line for small change in direction reducing fittings use. The leak tight joint is designed to eliminate infiltration and exfiltration from the pipe line system. The joints can easily be assembled with pipes reducing the installation time.

Advanced Technology & Flexible Manufacturing
GRP pipes are manufactured using advance technology and CFW process which gives products of high quality. GRP pipes can be manufactured in custom diameters and in any required length. This helps in easy installation especially in rehabilitation lining projects. GRP pipes produced with advance technology have lower wave celerity, which helps in reducing the surge and water hammer pressures.


To ensure that GRP pipes and fittings conform to universal specifications, exhibit the highest quality, performance, they are manufactured in accordance with the following international Standards and others:

  • AWWA C950 AWWA Standard for Fiberglass Pressure Pipe
  • AWWA M45 Fiberglass Pipe Design
  • ASTM D 3262 Standard specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) Sewer pipe
  • ASTM D 3517 Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) pressure pipe
  • ASTM D 3754 Standard Specification for “Fiberglass” (Glass-Fiber-Reinforced Thermosetting-Resin) sewer and industrial pressure pipe
