1. Strong pressure resistance and aging resistance. Made of high-quality modified PVC engineering plastic through one-time extrusion, it forms high molding strength. The grid-like structure inside the pipe forms a physical rigid structure, with a ring stiffness 10-100 times higher than ordinary plastic pipes. Under normal circumstances, no foundation or encapsulation is required, and it can safely replace steel pipes for crossing roads. It is self-extinguishing (good flame retardancy), corrosion-resistant, and aging-resistant, with a service life of over 50 years.

2. Complete specifications and diverse combinations. The product specifications include single-hole, 4-hole, 5-hole, 6-hole, and 9-hole options, accommodating optical cables of different diameters. It can be freely transitioned and combined with existing cement pipes, corrugated pipes, and other pipelines. Corresponding accessories such as joints, plugs, straps, specialized glue, and repair patches are available for convenient construction operations.

3. Innovative structure, saving pipe space. The external structure is an arc-square shape, allowing neat and convenient arrangement. It occupies minimal pipe space, only 10% of that of cement pipes, with small excavation volume, effectively saving urban underground pipe resources and minimizing impact on road traffic and the environment.

4. Good flexibility, free bending. A 6-meter-long pipe can achieve a bending chord height of over 1.2 meters. Special directional changes can be accommodated with specialized elbows. During construction, it can easily avoid curves or cross other pipelines.

5. Convenient construction, labor and time-saving. The sheath and sub-pipe are integrated, eliminating the need for secondary sub-pipe threading. Cables can be laid in one go, avoiding issues like deformation and twisting from secondary threading, sorting confusion, and repeated construction. It is easy to transport, has a smooth inner wall for effortless wiring, and features assembly marks on interfaces for orderly connection. With strong pressure resistance, the required burial depth is only 0.3-0.5 meters, eliminating the need for foundations and cement encapsulation. After backfilling with fine sandy soil to a depth of 20 cm, the road can be opened to traffic. Crossing roads does not require foundations or cement encapsulation. Using PE/corrugated pipes for road crossing requires additional steel pipes (which involve high steel usage, high cost, welding, cumbersome construction, susceptibility to corrosion, and short service life). Cement pouring requires a curing period, and secondary sub-pipe threading is needed for optical cable installation. Using grid pipes reduces the construction period by nearly half compared to PE/corrugated pipes and by nearly three-fifths compared to cement and steel pipes.

6. High utilization rate and low comprehensive cost. The internal grid structure is square, integrating the sheath and sub-pipes, providing large effective internal space. Cut sections can be connected for use, saving materials and reducing engineering costs. It saves nearly 20% in cost compared to using PE/corrugated pipes and can replace steel pipes, saving about 50% of the investment.

PVC grid pipes are versatile pipeline products with a wide range of applications. With their excellent performance and convenient storage features, they are widely used in construction, industry, and other fields. The main function of PVC grid pipes is wiring protection, serving as protective piping for power, network, and communication lines. Burying grid pipes underground and threading lines through them provides excellent protection, offering corrosion resistance, preventing damage from foreign objects, and avoiding interference between lines. Strong corrosion resistance: PVC grid pipes have outstanding corrosion resistance, able to withstand chemicals, acids, alkalis, and saltwater corrosion. This makes them perform exceptionally well in corrosive environments, ensuring long-term stable operation. Lightweight and easy to install: PVC grid pipes are lighter than traditional metal pipes, making them easy to transport and install. They are flexible and can be cut and connected according to actual needs, improving construction efficiency. For the storage of PVC grid pipes, the following points should be noted. First, avoid direct sunlight and rain during storage; choose a cool and dry place. Second, avoid contact with sharp objects and chemicals to prevent damage. Additionally, during storage, avoid stacking too high to prevent deformation or crushing. In summary, PVC grid pipes, with their multifunctional applications and convenient storage, are an ideal choice for many projects. They play important roles in drainage systems, ventilation systems, agricultural fields, and more.
