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:What is the method of making large diameter rubber joint?
- Rubber joint also known as shock absorber, shock absorber throat, the main function is to shock absorption, noise reduction, protection of the pipeline, compensation pipeline expansion, cold caused by displacement.Its structure: both ends are two carbon steel flanges, the middle is rubber shock absorption part.
- Q:What is a hose valve?
- The rubber tube is made of imported rubber and is made by special chemical formula. The utility model has the advantages of wear resistance, corrosion resistance, frost resistance, full sealing, no leakage, etc.;It is superior to gate valve, globe valve, regulating valve and stainless steel valve;It is convenient to overhaul, simply disassemble the valve body and replace the rubber tube. The valve body and the headstock can be used permanently. The cost is extremely low, and the service life can be raised by more than 3-5 times.Medium in the hose running, no flow resistance, do not touch the opening and closing mechanism and valve body, so as not to block the running parts, the operation is particularly flexible, greatly easing labor intensity.
- Q:What is the difference between plastic lined steel pipe and rubber lined steel pipe?
- Common ground1. the same matrix: carbon steel tube2., similar structure: are lined pipe, steel, rubber (plastic) composite3., corrosion resistance is close to: in most acid and alkali medium environment, can work properly
- Q:Production process and raw material of rubber
- Process selection: the tensile strength is the limit ability to characterize products can resist tensile failure. The main factors affecting the tensile strength of rubber are: the main valence bond, intermolecular force and polymer chain flexibility of macromolecular chains.
- Q:What's the detailed size of hose connection for shower?
- Hot and cold bath: take a bath with hot water before going to bed every day. The temperature of the water is within the limits of the body's tolerance. After washing, sleep in hot water for 15 minutes. After bathing was out of a sweat, after 3~4 minutes, and then into a basin of cold water or cold shower. Note that the hot and cold bath must be "hot before cold."".
- Q:What is the function between the rubber pipe joint and the installing pipe?
- The action of the rubber pipe joint on the installation of pipes:1. Small size, light weight, good elasticity, easy installation and maintenance.2. After installation, the transverse, axial and angular displacement of the pipe vibration can be absorbed. The pipe is not concentric and the flange is not parallel.3 、 after installation, it can reduce the noise caused by vibration of pipes, pumps and so on, and has strong vibration absorption ability.
- Q:The rubber is sheathed on a metal cylinder. How should they be connected?
- If you describe it, it is recommended that a soft binder such as 704 silicone gel will be used to prevent shock absorption and separation. Metal surface to rust treatment, clean can be coated adhesive, rubber cover surface is best polished, degreasing treatment effect is good!
- Q:How to distinguish the true and false corrosion resistant rubber soft joint?
- Method for distinguishing true and false corrosion resistant rubber soft joint:Put the rubber joint in the corrosive liquid which needs to pass. One day, 24h can see that the swelling ratio is not more than 5%!
- Q:The small hose attached to the grease gun is coarse or fine at the joint
- The small hose attached to the grease gun is threaded with fine thread. Usually M10X1 or Rp1/8.
- Q:How can I connect the gas tank connection hose?
- The general is directly inserted into the connector on the line, if loose, can use wire twist, still feel not reliable, can go to the market to buy two hoop, screw on the line.Keep it clean.
