HDPE Ppipe Basic Information:
Siphon rainwater drainage system is a new technology which is developed very fast in Europe,American ,Japan,South-American,Asia and Africa country. It is a more scientific and advanced technology,can be used on big construction buildings like factory,workshop,warehouse and public building.

Physical and mechanical property:
| Project | Requirement |
| Longitudinal reversion(110ºC) | ≤3% no delamination, cracking and blistering |
| MFR (5kg,190ºC)(g/10min) | 0.2≤MFR≤1.1 The MFR difference between the raw material particles should not exceed 0.2 |
| Oxidation induction time(200ºC/min) | ≥20 |
| Hydro-static Test (80ºC,165h,4.6Mpa) | No broken,no leakage |
| Ring stiffness (KN/M2) | SR≥4 |
| Combustion toxicity index | ≤1 |
UV resistance,aging resistance,the service life will be more than 50 years.
Smooth inner wall and less frictional resistance.
The pressure loss is about 30% less than the steel pipe, the smaller diameter HDPE pipe could be chosen.
PE pipe could be welded to be an organic whole system.
The inner drainage system have obviously advantage compare with the traditional gravity current drainage system construction buildings. The siphon drainage system is mainly composed of rainwater head,fasten systems,HDPE pipe and the corresponding design software. Compared with the traditional system,the siphon drainage system have advantages as following:
1. None-slope pipe
2. Less material used
3. Saving the cost
4. Less requirements for pipes' diameter.
Q1: May I get one sample before placing order?
Re: Yes, Sample are available. For normal products, samples are for free and you just need to bear the freight; For those high value products, you just need to freight and certain product cost. When we both cooperate for some times or when you are our VIP customer, free sample will be offered when you need.
Q2: Which payment is available for your company?
Re: T/T, L/C or Ali trade insurance. You can choose the one which is convenient for you.
Q3: How and when can I get my goods after payment?
Re: For small quantity products, they will be delivered to you by international courier(DHL, FedEx, TNT etc.) or by air. Usually it will cost 3-5days that you can get the goods after delivery. For large quantity products,shipping by see is worthwhile.It will cost days to weeks to come to your destination port, which depends on where the port is.
