Features 
 A compression 
 The high-quality anti-aging improved PVC engineering plastics an extrusion and high compressive strength, cellular (raster) like mechanical structure so that pipe 10 to 100 times higher than ordinary plastic pipe compression performance, normally without a foundation or encapsulation , anti-settlement, instead of steel pipe safety crossing the street, flame-retardant (away from the fire is put out good), corrosion resistance, aging resistance, service life of more than 50 years. 
 2, complete specifications 
 Diverse product portfolio, beautiful appearance, the main specifications are single-hole, 3 hole, 4 hole medium and small with Reducing 5 holes, 6 holes the size of the series of seven holes, 8 holes, the size of nine holes with different caliber light (electricity) cable facilities, are free transition with the original cement pipes, corrugated pipes, pipe, combination, and the appropriate connector, plug, cable tie, special glue, and other accessories to facilitate construction operations. 
 3, the structure of innovation 
 Save tube, tubing compact road excavation smaller, only 10% of the cement pipes, saving the city underground pipe digital resources, less impact on road traffic and municipal. 
 4, good toughness 
 Bending free 6 m pipe, bend radius of up to 4 meters, Construction, tripping over obstacles or other pipelines can be easily avoided. 
 5, the construction is convenient 
 Saving time and labor sheath the tubes into one, no secondary wear sub pipe laying can wear the cable to avoid the secondary through the sub-tube deformation kink, sorting confusion, repeat the construction of the trouble; light weight, easy handling; inner wall smooth, threading and effort; compressive strength, depth requires only 0.3-0.5 m without a foundation and cement encapsulation, and before backfilling sand stone 20 cm to return to the filling can be opened to traffic, cross the road without a foundation and cement encapsulation. PE / bellows (the amount of steel pipe, high cost, to be welded, heavy construction, life is short), cement watering required maintenance period, the second to wear the tubes to wear cable, perishable, use the grid honeycomb tube construction than using PE sub + tube bellows shorten the soil of nearly 1/2, the ratio of cement, steel pipe to shorten the duration of nearly 3/5. 
 6, high utilization 
 Set of jacket and the tubes, and lower total cost, the effective space of the inner hole, after truncation can be connected, saving material consumption, less investment project. Than using the PE / bellows cost savings of nearly 20%, and can replace steel, saving about 50% of the investment.
