HDPE three-layer wall composite reinforced pipe

Product introduction

"AD" brand HDPE three-layer wall composite reinforced pipe is a high-quality new pipe produced by polyethylene (PE) as the main raw material, using the composite reinforcement method and three-layer co-extrusion process. The pipe is composed of a smooth inner wall, a corrugated middle layer and a smooth outer wall. Compared with double-wall corrugated pipe, the product has significantly improved in structure and performance, and is an upgraded product of double-wall corrugated pipe.

Product Advantages

High ring stiffness, expanded application range:

adopts three-wall coating reinforcement process, the pipe wave height increases by nearly 10%, and the cross-sectional moment of inertia increases by more than 50%. It meets the technical requirements for the production of pipes with ring stiffness grade SN16 or above. The product has the advantages of high strength and a wider range of applications.

Reduce the difficulty of construction and improve the quality of the project:

Based on the principle of "pipe-soil interaction", the quality of backfilling of buried pipes during construction directly affects the overall quality of the project. Double-wall corrugated pipes are generally required to be backfilled with fine sand to ensure the quality of the project. However, in practical applications, due to the limitation of construction conditions and non-standard construction, the buckling and collapse of pipes caused by improper backfilling are still the main quality problems of plastic pipes in the application. The three-layer wall composite reinforced pipe, due to the smooth outer surface of the pipe, makes it easy to compact when backfilling, the quality of the project is improved, the excavation area is reduced, and the construction difficulty is reduced.

Three-wall integration, not easy to deform: The structure of the product is more reasonable and the integrity is stronger. The solid three-layer wall structure formed greatly increases the bending strength of the pipe in the longitudinal direction, and the ring flexibility of the pipe is also greatly improved.

Interface strength is high, and the connection is more reliable:

Three-layer wall online flared one-time forming process improves the stiffness and dimensional stability of the pipe socket part, making the rubber ring connection more reliable.

Large diameter:

One-time forming pipe belongs to the pipe with large diameter, and the maximum diameter can be DN1200.

Smooth drainage and sewage:

The inner wall is smooth, not easy to scale, strong water capacity and large flow.

Protects the pipe, easy to handle:

The composite layer plays the role of protecting the corrugation of the pipe, providing convenience for the pipe handling and construction.

Easy installation:

uses rubber ring flexible socket connection to meet the user's fast and convenient completion of construction.

Low cost and long life:

Comprehensive cost is lower than cast iron pipe and cement pipe, and the pipe has good anti-aging performance. The service life can reach more than 50 years.
