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: Rubber soft joint, what brand of good, the best price is more reasonable. Don't say anything expensive.
- The rubber joints produced throughout the country have the longest history in Shanghai, and have the characteristics of the type and sales volume of Gongyi city. They have been sold in the plumbing market all over the country
- Q: How to make a rubber tube requires flow
- Rubber pipes are made of high pressure rubber hose and low pressure rubber hose.Low pressure rubber hose is made of inner rubber, cloth, winding (cloth, winding layer number), outer rubber. High temperature processing and vulcanization.
- Q: What is the principle of communicating devices? What if the rubber tube is used as a connecting device to change the water for the fish?
- The principle of communicating devices can be explained by liquid pressure. If the same liquid is contained in a U glass tube, a small liquid AB is conceived at the center of the bottom of the communicating device. If the liquid is stationary, it does not flow. The pressure of the liquid in the left tube toward the right side of the liquid AB must be equal to the pressure of the liquid in the right tube toward the left of the liquid AB. Because in the communicating vessel is filled with a liquid, the same two liquid column density, according to the formula of P= P GH liquid pressure that only when both sides is equal to the height of liquid column, the liquid column is equal to the pressure on both sides of the liquid film AB. Therefore, in the case of no flow of liquid, the liquid level in each vessel of the communicating device shall be kept flat. (ideal model method) the connecting device is characterized in that the liquid level in each container is flat only when the same liquid is contained in the container. If the container is tilted, the liquid in each container is about to begin to flow. One end of the liquid column flows to the lower end of the liquid column and stops flowing until the liquid level in each container is normal. As with rubber tube two glass tubes connected together in container with a liquid, which will be a fixed tube, the other tube up and down or tilt, can see the two tube level in stationary phase remained flat. The connecting device is provided with the same liquid, but the pressure on the liquid surface is unequal, and the pressure difference of the liquid surface is equal to the pressure difference produced by the liquid level difference of the two container of the communicating device.
- Q: Is flexible rubber joint and telescopic device a kind of thing?
- The main features of metal pipe telescopic device are telescopic, large compensation and high temperatureUnder great pressure.And flexible rubber joint is a product!
- Q: How to distinguish the true and false corrosion resistant rubber soft joint?
- Soft joint products into your acidic medium, a bubble will know!
- Q: Which is safer for stainless steel bellows and rubber tubes for gas pipelines?
- The stainless steel bellows and the quick fitting joint connection way mostly uses the end face seal, may avoid the thread seal to be lax strictly the leakage, compared with the traditional installment, its leakage probability will reduce greatly.
- Q: How can I remove all the flavor on the rubber hose?
- Buy Rubber deodorant. Or dry, there is no other way.
- Q: Must the hose for the cooker be made of oil resistant rubber hoses?
- Yes, the rubber hose link range is required for oil resistance, because of the smoke in the kitchen, a long time will be attached to the rubber pipe, if it is not oil resistant hose is vulnerable to corrosion, resulting in a safety hazard.
- Q: What kind of material is the rubber tube with acid, alkali and high temperature resistance made of?
- Silicon rubber tube, also known as silicon rubber tube, ordinary silicon hose can withstand temperature of 250 degrees, high temperature resistant material of silicon hose can reach about 350 degrees. And its tear resistance and elasticity are very good. It is widely used in high temperature environment. If you don't understand, you can ask me
- Q: The selection of valves and fittings has the following requirements
- The joint of the valve is threaded with an internal thread, so that the connection in the installation is easier to select transition joints.
