Description of HDPE Siphon Fittings
CHUANGRONG Siphon pipes and fittings are made of high-density polyethylene, it has significant
advantages over traditional drainage systems. CHUANGRONG HDPE siphon pipe system has excell
-ent mechanical properties, physical properties and chemical properties. High impact and abrasion re
-sistance.
Resistors are very flexible and offer multiple connection options.
These comprehensive characteristics make it very suitable as a drainage material,
It satisfies the needs of building drainage well, and the stable quality ensures the safety of drainage
solutions.
Property of Siphon HDPE Pipe System
1. Sealing material
Refers to the Chemical Compatibility Guide or contact Geberit for help with the best connection method
because the chemical resistance of rubber seals is different from HDPE.
2. Noise
HDPE limits solid conduction,
However, airborne noise should be isolated. HDPE is a soft material with low Young's modulus. This can
be done through pipes or lagging.
3. Tightness
After proper installation
The joints will remain watertight for the life of the building. Because years of experience in welding HDPE
pipes have shown that butt and electric fusion
The weld forms a stronger watertight joint than the pipe.
4. Welding temperature
The welding temperature of HDPE is about 230 ° C, which makes welding easier and more
More reliable than other connection methods. Compared to many other materials, HDPE requires low ener
-gy input to produce.
5. Not suitable to Painting.
HDPE is not suitable for painting. Its water repellency and flexibility
Materials limit the adhesive properties of coatings. If unavoidable, paint
The product to be used should be tested for compatibility with HDPE.
6. 1)System principle:The working principle of the siphon drainage system depends on the special design
of the rainwater hopper implement separation, So that the rain is flowing state in theriser, when the rain
reached a certain capacity in the riser, siphonage is generated.In the process of rainfall, due to the cont
-inuous siphonage, the whole system is able toquickly rule out water from the roof. Butt Fusion Welding
and Electrofusion Welding.
6. 2) System composition: The siphon drainage system is mainly composed of rainwater head, fastening
systems,polyethylene pipe and the corresponding design software
6.3) Advantage of system:Compared with the traditional gravity drainage system, the siphon drainage
system without slope;less material; the construction are greatly reduced; reduction of pipe diameter;
save installation space;pipe has self-cleaning function;design, construction is simple and quick;widely
applicable to various purposes buildings.
6. 4) Features:1, black PE pipeline uv resistant, ageing resistance, long service life of 50 years.
7. Smooth inner wall, and does not change with time, small frictional resistance,save energy, the pres
-sure loss about 30% smaller than the steel tube,can choose smaller than steel pipe diameter. Health
performance is good, no additives, no possibility of pollution of drinking water, ISO standard grading
polyethylene material level 0 (the lowest), no mildew material, compared with some other commonly
used plastic material of polyethylene is much mildew resistance, use for a long time also not fouling.
8. Polyethylene pipe can be welded joint with pipe become an organic whole, without the possibility
of joint leakage, water saving, reducing operation cost and maintenance cost examination, pipe can
be manufactured in any length, but the flexible layout, saving fittings.
9. PE pipe installation available welding or fused to form a completely closed seepage control system.
10. Light, easy to install, handling, connection, construction is convenient and reliable.
11. Has good flexibility, small can winding pipe, pipe winding along the ditch, can resist formation geolo
-gical change, can be used as liner repairing old pipeline.
12. Good low temperature resistance, corrosion resistance, long life, buried pipeline within to 40 °C and
40 °C.
