1. The inner and outer walls of the casing are smooth and the friction coefficient is small. Can reduce the resistance of wire and cable in the pipeline.

2, high compression performance, can be installed in the concrete can also be dark, not compression damage, medium and heavy pipe series suitable for dark compress in concrete.

3, good impact resistance, heat resistance, casing in the concrete pouring process, can withstand normal tamping impact without cracking, and under the action of concrete condensation, will not soften deformation.

4. The casing has excellent moisture resistance, acid resistance and alkali resistance, will not rust, and acid, alkali resistance and oil resistance. The joints are bonded with PVC adhesive according to the regulations, which can be waterproof and permeate into the pipe, and the moisture-proof effect is better. Therefore, it is suitable for use in corrosive environment.

5, good flame retardant performance, with inflammability, not easy to burn characteristics. The flame will not spread along the pipe.

6, casing has excellent insulation performance, high breakdown voltage resistance, no electrical danger. Can effectively prevent accidental leakage, electric shock accident.

7. Pest control, the casing will not send out the odor that insects like, which can avoid the damage caused by insects biting.

8, the casing toughness is good, easy to bend, casing pipe only need to insert a corresponding special spring, no heating at room temperature with the hand gently force, can be bent into the required Angle.
