Excellent Structural Strength

Structural design of E-mo no & H-dual Gapex corrugated drainage pipes attribute the flexibility characteristics of HDPE together it provide excellent structural strength for its integrity. When the pipes subject to loading, they are able to disperse point loading to its surrounding soils. With such, pipes can be much lighter in weight but provide excellent crush resistance. For instance, with a minimum 300mm of soil coverage, H-dual can undertake a H-20 surcharge loading.

Durability

Both ductility and molecular structure of HDPE materials render superb durability of Gapex corrugated pipes. Ease of transportation and installation can be obtained due to its low density. The superb corrosion resistance of HDPE reveals application result that material loss at HDPE piping system is 20% less than concrete pipes. HDPE offers excellent resistance to acids and alkaline: it can safely be used with PH range from 1.5 to 14. In addition, HDPE can maintain its performance even at subzero temperatures. Thus, Gapex pipes are an attractive option in rigorous environments .

Flow Efficiency

Gapex H-Dual pipe provides an excellent smooth inner wall which reduces the flow friction resistance greatly and also provide superb corrosion resistance against pipe wall. This enhances the durability of the pipe and ensures maximum flow capacity.

Light-weight, Easy Installation

Thanks to the lightweight property of HDPE, for example a ONlOOO concrete pipe is 13 times heavier than HDPE corrugated pipe, Gapex corrugated pipe can be handled, transported and installed with ease. This renders easier installation and cutting, lessen onsite work crews, reduced the need of heavy equipment and improve safety at work. At conditions where pipe needs to be cut on-site, Gapex corrugated pipe excels.

Because of the light weight of HDPE corrugated pipe, the length of the pipe can be manufactured up to 6 or 9 m. This means less joints, faster installation , and reduced risk of leakage.

Flexible

The remarkable flexibility property of HDPE material comes for its inherent distinctive molecular structure. Superimposing the flexibility with the corrugated profile design, Gapex HDPE corrugated pipe demonstrate its superior flexibility than vitrified clay or concrete pipes. Especially when single wall pipe is adopted at most golf course or greening projects, large elimination of fittings are feasible. With reduction of connection fittings, more simple installation and economic drainage solutions can be provided.

Fast Flow Drainage

Gapex HDPE corrugated pipe offer a variety of perforation patterns. All such patterns are strictly conform to BS or ASTM' s flow requirements. At golf courses and athletic fields application, HDPE perforated pipes provide quick repsonse to transport and divert rainwater away from the subsoil after intense rainfall, with such the turf can resume to normal operation at shortest time.
