PE pipe for gas pipe
Product Name: polyethylene pipes for gas supply
PE gas pipe is made of PE80 and PE100 to be produced by extrusion molding ,suitable for operating at temperature of -20℃～40℃.According to production and testing requirements of national standards GB15558.1-2003 (Gas buried polyethylene pipe) ,wall thickness can be divided into: SDR11 and SDR17.6.SDR11 series for transporting artificial gas, natural gas, liquefied gas;SDR17.6 series for transporting natural gas;nominal diameter of DN16-DN630mm.
Features of PE gas pipe:
PE gas pipeline has many excellent features, such as corrosion resistance, toughness, hardness and softness;also reflects the excellent performancein some special applications . For example,polyethylene pipe has solved corrossion and leakage presence of the traditional steel pipe fittings , and low cost. In addition, the outdoor line and pipeline is laying in the corrosive soil or in the earthquake zone, mountainous and swampy areas .
Main advantages
(1) corrosion resistance
Polyethylene is an inert material, except for a few strong oxidant, can be resistant to a variety of chemical media. No electrochemical corrosion, no coating.
(2) does not leak
Polyethylene pipe use mainly hot melt connection or fused connection,to achieve integration between joint and tubing. Compared with the rubber ring joints or other mechanical joints, because there is not dangerous that joint distortion causes leakage.
(3) High toughness
The elongation at break generally over 50%. excellent seismic performance had become proved in Wenchuan earthquake.
(4) PE pipe has excellent flexibility to be coiled.
Longer length supply without the need for a variety of connection fittings.
(5) good anti-scratch ability
Ability to resist scratches and slow crack growth (SCG) is close.Studies have shown, PE80 gas pipe has better ability and resistance to scratches . PE100 gas pipe have a better ability to resist ing scratches.
(6) Excellent resistance to rapid crack pass.
(7) Long service life up to 50 years
(8) good impact resistance, heavy directly pressure through the pipe will not cause pipeline rupture.
(9) compared with steel, cast iron pipe and steel mesh composite pipe , convenient construction and lower total cost.
Application:
1. Gas Transportation
2. Liquied gas transportation
3. artificial gas transport
4. Industrial gas
5. Industrial corrosive liquid feed delivery

- Q: How can I keep the rubber tube for stethoscope?
- I don't think this question should be considered purely from the point of view of sound transmission.
- Q: What happened to the soft rubber flat?
- A slightly heated or pressurized medium will return to its original condition.
- Q: What are the types of cable metal hose connections?
- Mainly used for internal thread connection pipe and the hose thread cable.
- Q: What are the categories of hose?
- A rubber hose products structure: hose cloth; woven hose (fiber braided hose, steel wire braided hose); winding hose (fiber winding hose, hose winding wire); knitted hose, hose and other circular weaving hose (rubber hose, rubber and plastic composite hose and hose, drilling hose, etc.).
- Q: What are the methods of sterilizing rubber hoses and Perspex?
- Our laboratory rubber tube is directly into the steam sterilizer. After a few cracks, throw them away and use the new ones. Plexiglass products, we are placed on super clean bench, UV irradiation above 30min. Sometimes it takes time to wipe with 60% alcohol cotton ball.
- Q: Will the electric water heater be well connected with metal hose or hose?
- For electric water heater, now the industry is required to use PPR pipe to its inlet and outlet for welding, on the one hand, long service life, can effectively prevent the water heater inlet and outlet leakage;
- Q: Can high speed air flow through a rubber tube and produce static electricity?
- To solve this problem, I suggest you do not focus on the voltage level, but focus on how to eliminate static electricity. For example, choose a low resistivity rubber material to ground and control the airflow humidity (if possible).If you really need to accurately grasp the size of the voltage caused by static electricity, and there is no reference to the literature, you may as well begin to study the experiment.
- Q: The gas water heater uses metal pipes and rubber pipes
- Gas water heater using metal pipe, good heat resistance, no aging!
- Q: Excuse me, how can I get waterproof wires in the water?
- You can find a little longer than the water into the rubber tube, the wire will be worn, the rubber tube fixed, so that the water is only rubber hose. After a period of time, check that the hose is leaking so that it can be kept dry for a long time.
- Q: Laboratory condensate water pipe must use rubber tube, shall not use latex tube reasons
- Bending test: after bending the hose to a certain extent, measure the minimum outside diameter of the bending part and the ratio of the outside diameter before bending, the passing capacity of the steel ball and the bending force when the tube is pressurized.
