Specifications︰Glassfiber Reinforced Plastics (GRP) Pressure Pipes are used for drinking water and hydropower pipelines as well as for other applications.

Nominal Stiffness [SN] up to 20000 N/m²

GRP Pipe Material
Glass fiber reinforced plastics (GRP) are a composite consisting of at least two different materials. The benefits of each material are united to achieve an overall effect.

A binder or matrix and reinforcing material is commonly used to combine the physically differing raw materials. Their molecules do not bond but they form a composite by joining their boundary layers. What is important is that the constituents are compatible in terms of properties and processing. This technology originated in the aviation and marine industry where particularly light high-performance materials are required.

Pipes made of centrifugally cast glassfiber reinforced plastics (GRP) consist of a combination of thermosetting plastics such as for example unsaturated polyester or vinyl ester resins, chopped glass fibers and reinforcing agents. The standard wall structure ensures that the individual materials bring their special features to bear in the finished composite.

Stiffness Classes
SN 2500 These pipes are suitable for buried installation, but are mainly used for relining.
SN 5000 Pipes of this stiffness are selected for minor loads, for example when installed in mixed soil at a depth of 3 m and a live load corresponding to a
60 t truck.
SN 10000 These pipes are designed for high loads, for example for installation in mixed soil at a depth of 4 m or a live load corresponding to a 60 t truck with little soil cover.
SN >10000 For special cases pipes can be produced with stiffnesses up to well over 500,000 N/m², e.g. for landfill or well pipes.

Corrosion Resistance
Pipes do not conduct electricity and are not susceptible to attack caused by acids, alkalis and salts.

train Corrosion Test
A test used to determine how GRP pipes will react in the field is the strain corrosion test, which checks for stress corrosion cracking. Specimens are subjected to both physical (structural design) and chemical (medium) loading, i.e. the pipe is held in a deflected state in a sulfuric acid solution. The results of the standardized test according to ASTM 3681/3262 (American Society of Testing Materials) are conclusive because it is conducted on a pipe section on a scale of 1:1. It therefore reflects practical applications under more extreme conditions as closely as possible without requiring unnecessary tests for individual criteria that can also be contradictory in the case of composites.

Hydraulic Properties
GRP pipes have excellent hydraulic flow characteristics with significantly lower friction losses than other products of similar dimensions. Not only are the hydraulic properties favorable, the smooth resin rich inner lining provides protection against highly corrosive media and the internal surface is not prone to tuberculation and encrustation.

Pipes have the following hydraulic roughness values.

Roughness Coefficients for Pipes
Colebrook-White k 0.01
Hazen-Williams C 155
Mannings n 0.008-0.01
As a result, less energy is required to transport the liquid through the pipe. The amount of energy saved (pressure pipes) is an important aspect that has to be taken into account regarding the cost-effectiveness of a pipeline system. Given the smooth seamless liner, sludge deposits and incrustations are minimized. Maintenance and cleaning costs are therefore kept low and the planned pipeline is more efficient right from the outset.


The FRP pipe is consist of inner layer, Structural layer and outer layer. Its characteristics are:

1. Lightweight, high strength and high stiffness, its density is 1.5-1.9, equals one fifth of steel pipe, one fourth of cast steel pipe and three fourth of pretensioned concrete pipe(PCP).

2. Corrosion-resistant property. The Corrosion-resistant property of FRP pipe is mainly relied on the inner resin, and it can be selected based on the condition of the media.

3. Good hydraulic property. The inner surface of the FRP pipe is very smooth, its friction coefficient (f) is 0.000915 after performed the relative testing, the water conservancy factor (c) can be kept within 145 and 150 during a long period.

4. health property. For the pipe which be used for transporting the potable water, the food grade resin will be used. It has been approved by the relative national sanitary authority.

5. Shock resistance. It doesn’t occur delamination and cracking under the condition of deformation of 25%.

6. Abrasive resistance. The inner surface is made of one kind of resin with good abrasive resistance, so it can improve the abrasive resistant property of the FRP pipe.

7. Low temperature resistant property. There will not be cracking under the condition of -40℃ and the strength doesn’t decline.

8. It can be used for different kind of environment, such as beach, benthal, river, mountain area, marshland, desert and plain etc.
