Hangzhou self reinforced power communication environmental protection pipe co pipe

  Opvc cable protection pipe is a kind of high compression and high impact pipe made of biaxially oriented PVC-O pipe with compression and impact resistance, which is made of PVC blending modified raw materials and tensile orientation in circumferential and axial direction
At the same time, in order to implement the national environmental protection law, according to the national soil environmental quality standard GB / t15619-1995, ambient air quality standard GB / t3095-2012 and t17219-1998 and other national standards, the production process of compression and impact biaxial oriented PVC-O pipe adopts full environmental protection formula, which fully meets the green environmental protection performance, and can be fully used to build key projects of green environmental protection and benefit the society
The products are used to protect the cables of excavated roads, airports and light rail roads and replace the trenchless pipes of MPP, PE and steel pipes
Product features 1 High compressive strength (ring stiffness): the elastic modulus reaches 4000mpa after taking the back through biaxial; With the same wall thickness and outer diameter, the lower ring stiffness is 1
4 times that of PVC, 5 times that of PE and 4 times that of MPP; 2
Excellent low-temperature impact cracking resistance
The product can be laid and used at - 20 ℃; 3
High tensile strength: 1
5 times of PVC pipe and 3 times of PE / MPP pipe
In the Trenchless Pipeline at the same distance, only about half of the wall thickness of MPP / PE pipe is required; 4
Strong corrosion resistance: immerse in hydrochloric acid, sulfuric acid, nitric acid and sodium hydroxide at 50 ℃ for 5h, and the quality does not change; 5
Good electrical insulation performance: volume resistivity 1016ohm cm； 6
Environmental protection: environmental protection raw materials are used
Under the same performance, the product materials are less used than PVC, PE and MPP, with lower energy consumption and carbon emission
It is a material for sustainable development
