1. The medium pipe and heavy pipe can withstand the pressure of more than 750N and 1250N respectively, so they can be installed in the open or concealed way in the concrete without compression cracking. The heavy pipe series is especially suitable for concealed laying in the compacted and vibrating concrete.
2. During concrete pouring, the tremie can withstand normal tamping impact without cracking, and will not soften and deform under the effect of concrete setting.
3. It has a high oxygen index value, so the pipe is not easy to burn, and it will self extinguish when it is out of fire, and the flame will not spread along the pipe.
4. PVC conduit has good acid and alkali resistance, will not rust, and does not contain plasticizer, and has no odor attracting insects and rats, so it is free of pests.
5. AC2000V, 50HZ will not be broken down in the water immersion state, and the insulation performance is excellent, so it can effectively prevent accidental leakage and electric shock accidents.
6. It is convenient to cut off the conduit. The conduit below D32 can be bent to the required angle at room temperature by inserting corresponding special springs. PVC adhesive can be used to conveniently connect the conduit to the shape required for construction.
