Tengyuan can supply municipal engineering pipe, dredging engineering pipe, HDPE Gas Pipe, Power Engineering Pipe, Mining Pipe and agriculture irrigation pipe, etc. Integrity is the foundation of us, as well as the guarantee for enterprise's sustainable development. System Advantages Compared with the traditional gravity drainage system, the siphon drainage system has advantages as follows: 1. None-slope pipe. 2. Less material used. 3. The construction cost is greatly reduced. 4. Reducing the requirement of pipesâ?? diameter. 5. Save installation space. 6. The pipe has its self-cleaning function. 7. The design and installation is simple and quick. 8. Widely applicable to various buildings. Features: 1. UV resistance, ageing resistance, long service life of 50 years. 2. Smooth inner wall and tiny frictional resistance. 3. The pressure loss is about 30% less than the steel tube, so smaller diameter of HDPE pipe could be chose. 4. Health performance is good. No additives and no possibility of pollution of drinking water,ISO standard grading polyethylene material level is0 (the lowest)and no mildew material. Compared with some other commonly used plastic material, PE is much mildew resistance and it could be used for a long time without fouling. 5. PE pipe can be welded to be an organic whole system.
