1st, loses the current capacity greatly ring-like ripple structure,has fine mechanics performance which hard and softly has both,surrounds the rigidity in a big way, the flexibility is good,resistant to compression, bears the i***ct.
2nd, pipeline endophragm smooth, fluid friction resistance small,outstanding hydraulic characteristic, in the same level diameter andthe design slope, the current capacity co***res the concrete pipe-linetransmission capacity to be big; .
3rd, center ***tial rib structure, weight light, does not need thespecial-purpose hoisting facility, the transportation, theconstruction is convenient, reduces the operating charges.
4th, connection convenient, the attachment leak-proof quality goodlong-term movement quality is reliable, the seal packing collarreceives inserts the connection, the flexible connection, the anti-subsidence, does not divulge, does not have any pollution to theenvironment
5th, the chemical property is stable, anti-corrosive, non-toxic doesnot have the pollution, is the environmental protection tubing
6th, anti-corrosive, bears the low temperature, the resistance to wearwell, bears the aging, the anti- dehiscence buries the service life tobe possible above for 50 years, uses in the cable sheath bond tubing,has the good electric insulation performance and burns without flamesthe nature, durable, the cable line movement safe is reliable.
7th, a better intensity and the rigidity, the suitable дс curvature,belongs to the soft tube, but does not need the fitting directly tolay down the tubing Yu Luewan in the trench, also not ground certaindegree differential settlement influence |
