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:Do I need a shim for the flat metal hose joint?
If one of the two interconnected joints is one of those with a groove and a O ring, it would be better to put the O ring in it and seal it better.
Q:The engine cylinder head cover behind the drop rubber tube what reason (Xichai 490 engine) (note the valve chamber cover tube)
The valve chamber of the engine cylinder head cover counterclockwise with 8~10 open wrench counterclockwise unscrew rocker screw. Place the piston at the top dead center, turn the rocker head wire clockwise until the hand can not be moved, then back half a circle, then lock the nut.
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:Three yuan ethylene propylene rubber joint (high temperature resistant rubber joint) can withstand high temperature
High temperature rubber joint adopts three yuan ethylene propylene rubber processing, can withstand high temperature 140 degrees, if need higher temperature, need to use fluorine rubber, the highest temperature can reach 200 degrees!
Q:What's the difference between hose and hose for compressed air?
In use, it is usually marked with color. For example, the intake is made of blue, and the exhaust is made red, but it is not necessary.
Q:What does the letter of the high-pressure tubing connector mean?
Purpose: high pressure tubing tubing steel wire spiral reinforced layer and wear resistant synthetic rubber composition used for conveying high pressure, engineering machinery hydraulic oil, gas, petroleum, submarine irrigation, steel mills, chemical plants and other media.
Q:High pressure hose K type joints KJR32 and KJR31.5D what is the difference between ah, please give us a answer,
K type joint has the distinction between national standard and German standard. In general, 32 and 38 tubes are used more often. The joints used on 32 of the tubes are KJR32 and KJR31.5D. 38. The joints used on the tubes are KJR38 and KJR B40
Q:How can the soft joint of the pipe be elongated during use?
Because the pipeline joint is a kind of soft rubber products, in the use of high temperature and high pressure rubber is easy to deform or due to internal pressure is easy to crack and surface as the main parts of long distance pipeline, influenced by the use of the process will produce corrosion phenomenon,
Q:What are the gas hoses?
The stainless steel is expensive, 40 yuan set.The rubber is cheap, 10 yuan a set.Where do you come from? I don't know. In our Shanghai gas, this price includes the labor cost of the installation to you. In other words, fix it directly for you.
Q:Which is safer for stainless steel bellows and rubber tubes for gas pipelines?
Stainless steel bellows long service life, because the tube is made of high quality stainless steel as material, so the pipe is not easy to aging, greatly improve the service life.
