Underground communication pipe PVC porous integrated pipe
The PVC communication straight buried pipe is a new type of optical cable protective sleeve, which is convenient for guiding, isolating and protecting the optical cable. The product has obvious advantages such as improving work efficiency, saving costs, convenient installation, stability and reliability. It is widely used in optical fiber communication, cable television, power cable multimedia transmission and other basic projects. It is a new and practical supporting product for optoelectronic communication facilities.
Product performance characteristics
1. Strong pressure resistance and aging resistance. High-quality modified PVC engineering plastic is used for one-time extrusion, high compressive strength, no foundation or encapsulation under normal circumstances, anti-settling, can safely cross the road instead of steel pipes, flame retardant (good self-extinguishing ability), corrosion resistance, aging resistance With a service life of more than 50 years.
2. Complete specifications and various combinations. The product has a beautiful appearance. The main specifications are 3 holes, 4 large, medium and small 4 holes, 5 holes with the same diameter and 4 holes (different diameters), 6 holes, 7 holes, and 9 holes. They are matched with optical (electric) cables of different calibers. With the original cement pipeline, corrugated pipeline and other pipelines can be freely transitioned and combined, and have corresponding joints, plugs, straps, special glue and other accessories, easy to operate.
3. Innovative structure, saving pipe position. The pipe structure is compact and the amount of road excavation is small, which is only 10% of the cement pipe position, which effectively saves urban underground pipe position resources and has little impact on road traffic and municipal administration.
4. Good toughness and free bending. A section of 6-meter pipe with a curved chord height of more than 1.2 meters can be easily avoided when encountering obstacles or crossing other pipelines during construction.
5. Convenient construction, saving labor and time. The sheath is integrated with the sub-pipe, and the cable can be passed without having to pass through the sub-pipe once, avoiding the deformation and kinking of the second sub-pipe. ; Strong compressive strength, the burial depth only requires 0.3-0.5 meters, without foundation and cement encapsulation, backfill the fine sandy soil 20 cm first, then backfill the soil to open to traffic. When using PE / corrugated pipe to cross the road, another steel pipe must be used. The construction time of pipes and honeycomb pipes is shortened by 1/2 compared with the use of PE / corrugated pipes, and shortened by 3/5 compared with the use of cement steel pipes.
6. High utilization rate and low comprehensive cost. Integrating the sheath and the sub-tube, the inner hole has a large effective space, and can be used after being cut off, saving material consumption and less engineering investment. Compared with the use of PE / corrugation, it saves nearly 20% of the cost, and can also replace steel pipes, saving about 50% of investment.
