Long, effective service-life materials, up to 50 years. Smooth inner walls, absolute roughness of 0. Ease of joining, high construction efficiency, reducing installation time.

DN15 – DN mm. Other design pressure, stiffness, non-standard length of pipes can all be customized. ISO Plastics piping systems for pressure and non-pressure water supply-Glass reinforced thermosetting plastics GRP systems based on unsaturated polyester UP resin. BS Specification for glass reinforced plastics GRP pipes joints and fittings for use for water supply or sewerage.

Therefore, compare with traditional pipe, we can choose smaller diameter pipe or lower power pump to transmit same flow. It also provides excellent corrosion resistance, long life, few maintenance cost. And it will not crack for cold medium and weather. It is asttm for many chemical applications include strong acids, chlorine, salts and oxidizing agents that corrode transitional metal pipe. Good atsm and cold temperature resistance: Good insulation, thermal conductive and transparent property.

Long life, up to 50 years. Light weight and high strength. Pressure test will be done at 1. ISO Plastics piping systems for pressure and non-pressure water supply — Glass reinforced thermosetting plastics GRP systems based on unsaturated polyester UP resin.

The excellent advantage for the polyurethane interlayer are cold resistant, heat insulation, light weight, big adhesive area with the outer protection pipe, uniform load transferring, good impact resistant, etc. Lightweight, high strength, convenient transportation, installation and maintenance, the heavy lifting equipment is not required. No fouling on the inner surface, through long-time use, the smooth inner surface also can be kept. Good chemical resistance and long life time can up to 30 years.


Prefabricated insulation layer, saving installation time and cost than fabricated on the construction site. Thermal spring delivery pipe.

ASTM D2996 – 17

City and factory heating system. Other heat medium feed pipe. Easy installation and maintenances. Municipal, electricity, chemical industry, irrigation, water supply, drainage and sewage. Spray pipeline, oxidation air tube, slurry pipeline, oxide satm spray gun, strainer mesh, etc.


Use epoxy vinyl ester resin can resist sulfur smoke and acid-base liquid. Computer control winding process, greatly improve interlaminar adhesive properties. According to the following international standard: Facebook Twitter Google Pinterest. Total 12 Related Items.

Reinforced Ring Piping I. Glassfiber Reinforced Plastics GRP Pressure V2996 are used for drinking water and hydropower pipelines as well as for other applications. 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. SN 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 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. High abrasion resistance UV resistance High structural load capacity Compatibility with other materials Low operating and maintenance costs Service life of more than 50 years Corrosion Resistance Pipes do not conduct electricity and are not susceptible to attack caused x2996 acids, alkalis and salts.


Specimens are subjected to both physical sstm design and chemical medium loading, i. 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. 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 astk 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. Lightweight, high strength and high stiffness, its density is 1.

ASTM D Specs – Beetle Plastics

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. The inner surface of the FRP pipe is very smooth, its friction coefficient f is 0. 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. 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.

Low temperature resistant property. It can be used for different kind of environment, such as beach, benthal, river, mountain area, marshland, desert and plain etc. These revisions include the following:
