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: Can black soft rubber pipes be used as water pipes? Why is there a pungent odor?
- If you have a strong smell, it must be made of reclaimed gum, and it's inferior reclaimed gum. You smell the smell of reclaimed tar.
- Q: Pipe rubber shock absorber: flexible joints and flexible connections are not the same thing
- Flexible joint is a kind of special joint. Its performance characteristics can be generated by transverse, axial and angular displacement when it is installed. It is not limited by the pipe and the flange is not parallel. Generally, rubber parts reinforced with fabric are composed of flat movable fittings, loose metal flanges or threaded pipe flanges. They are used for vibration isolation, noise reduction and compensating displacement of pipes.
- Q: Can the natural gas hose not exceed 1.5 meters or 2 meters?
- The gas hose on the principle of not more than 1.2 meters, and regularly check the technical requirements, 1-2 must be replaced if the temporary gas can also be longer, if long-term use, as far as possible the use of metal pipe joint and the gas stove can also use metal hose, high safety factor.
- Q: What advantages does the Parker hose have in comparison with other hydraulic hoses?
- Parker hose and other hydraulic hose advantages compared to:First: from the price point of view, the price of PAKER is the most expensive industry. High popularity.Second: if from the quality point of view, the quality of stability, high degree of recognition.Third: from the point of view of use, the difference is not obvious. PAKER things match well.Fourth: strong pressure resistance, rated 400bar hose, blasting pressure can reach close to 1000ba
- Q: How to detect the reliability of rubber hose
- Suction flat test: in the 1min vacuum, after maintaining 10min, with diameter of 0.9 times the diameter of the hose rolled over, check the degree of collapse of the hose. Some standards used to measure the rate of change in the outer diameter of the hose to indicate the extent of deformation of the hose.
- Q: How do the rubber tubes fit into the galvanized pipe?
- If the rubber tube is outside the galvanized pipe, when the rubber is ordered, the inside diameter shall be greater than the outer diameter of the galvanized pipe. If the rubber tube is inside the galvanized pipe, when the rubber is ordered, the outer diameter of the rubber pipe will be galvanized and the inner diameter of the galvanized pipe will be inside
- Q: How to determine the tensile strength of GB rubber joint?
- In the middle of the specimen, 4 parallel lines marked by the mark mark are used to mark two distances equal to the standard distance (type 1 is 25mm, type 2 is 20mm, and type 3 is lOmm), and each reticle shall be equidistant from the center of the sample. If the non-contact deformation measuring device is used, the proper marking device shall be used, and two parallel markings shall be placed on the narrow parallel part of the sample. Each mark shall be equidistant from the specimen center and perpendicular to the long axis of the specimen, and the specimen shall not deform during the marking.Style cutting, punching machine blanking note the above points, is to test the tensile strength of rubber joints based on, but also guarantee.
- Q: How can I remove all the flavor on the rubber hose?
- Buy Rubber deodorant. Or dry, there is no other way.
- Q: Flexible rubber joints. What do they mean by flexing?
- Stainless steel bellows are not a kind of rubber joint.Flexure generally means that it can be bent repeatedly.The rubber joint mainly plays the axial and angular compensation displacement, and withstands the mechanical vibration, protects the pipeline not to burst.Stainless steel bellows can also be flexible, but the performance of vibration proof is better than that of rubber joints. If the requirements of the engineering drawings are rubber joints, it is better to be careful. Don't change it indiscriminately. Otherwise, the service life will be affected
- Q: What with the appropriate suction tube Dichotomanthes tube and rubber machine
- The spiral tube called spiral steel tube or spiral welded pipe, the low carbon steel or low alloy structural steel strips in a helical line certain angle (called forming angle) rolled into a tube, then the tube welding seam made up, it can be used in narrow strip production of large diameter steel pipe spiral pipe is mainly used in oil.
