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: 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: Is the electric water heater well connected with the metal hose?
- The electric water heater, now in the industry are required to use PPR on the inlet and outlet pipe welding, a long service life, can effectively control the water heater outlet Water Leakage; on the other hand, can avoid the water heater power switch for two grounding and frequent take-off effectively. Therefore, the metal pipe connection does not meet the safety and installation specifications
- Q: The basic buret is a rubber tube is inlaid with a glass bead to replace glass piston. Why this burets cannot be used to install Potassium Permanganate solution?
- Are made of glass, acid burette glass piston burette, no piston, just at the tip of a rubber tube, rubber tube with glass beads, glass or the lower beak. Why not the same because of acid burette, glass and alkali reaction, generate silicate, sticky, if it is very easy to use acid burette, the hole is blocked, damaged burets.
- Q: How to remove hose odor?
- When rubber is peculiar, it can be scrubbed by hydrogen peroxide. After drying, the odor will disappear. Or with waste tea sent to rubber products, tea has the role of adsorption odor.
- 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: How to replace natural gas hose? Steps?
- Replace the natural gas hose first pressure relief, and resolutely put an end to the operation with pressure;According to the connection way of the hose, if it is O ring sealed, just tighten it directly;If it is cone thread, it can be wrapped with raw material tape or sealant.
- Q: Why should the water stop strip be joined by heat instead of superposition?
- Lap joint of rubber water stop belt is lap joint, this method is not allowed in engineering, glue glue and do not use overlay. In the case of splicing, it is equivalent to not doing any treatment at the joint. In the process of pouring, the sealing strip is prone to roll and twist.
- Q: How long is the service life of a rubber tube?
- It depends on the environment, and what brand of hose, the general import of plastic pipe used relatively long, our family's sewage pipe with IVG used for several years
- Q: The difference between silicone tube and rubber tube
- The main performance of the rubber tube: rubber tube is non-toxic, environmental protection, physical inertia, UV resistance, ozone resistance, resistance to high temperature (-8 to 300), high transparency, strong resilience, resistant to compression permanent deformation, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame resistance, voltage, conductive properties.Scope of application: supporting electrical appliances, electronics, furniture, equipment, toys, hardware, medical equipment, sporting goods, audio, lighting, machinery, automobile and other industries.
- 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.
