Applications of liquefied petroleum gas hose: oil fields, refineries, chemical plants, liquefied gas.
Transmission media: liquefied gas, liquid ammonia, propylene, organic solvents, micro particles, etc.; not used in tank trucks, tankers; vacuum-resistant; antistatic outer layer; widely used in various petroleum products, aromatic compounds content can be as high as 50%.
Advantages of liquefied petroleum gas pipe products: The inner rubber layer is made of NBR synthetic rubber, which has excellent resistance to corrosion by liquid petroleum gas. The reinforced layer of the pipe body can be selected from cord weaving or steel wire weaving according to different pressure levels. If customers have anti-static requirements, they can also be considered to provide you with static conductive liquid petroleum gas (LPG) rubber hoses (with conductive copper wires built into the tube body).
Liquefied Petroleum Gas Pipe Product Features: The hose has the advantages of small inner and outer diameter tolerances, oil resistance, wear resistance, ozone, anti-static and other properties, light weight, soft and durable pipe body; corrosion resistance, anti-aging, light weight and fast flow , Compression-resistant steel wire is not easy to break, do not stick hands, extend the service life of the hose.
1. Resistance to ozone aging: the concentration in the standard experiment box is 50+/-5pphm, temperature is 40+/-2℃, and the experiment time is 72t without cracks.
2. Heat-resistant aging: 70+/-1℃72t tensile strength change rate within standard aging box within -25% elongation within -30%.
3. Physical properties: elongation of inner and outer rubber layer ≥300%. The hose has good elasticity under the environment of -30+/-2 ℃ 5t. 4. There is no cracking and breaking after bending 180°.
5. Corrosion resistance: The inner and outer rubber layers are oil resistant to RMA-B grade and resistant to hexane corrosion. They also have RMA flame retardant requirements.
Precautions for liquefied petroleum gas hose: gas hoses must use qualified gas special hoses, and the length should not exceed 2 meters;
When installing, be sure to insert the hose in place and fix it firmly with throat codes at both ends to prevent air leakage caused by looseness;
Do not fold the hose when using it, do not use it through the wall, and do not bury the hose underground;
During the use of the hose, it should be regularly checked and cleaned, and cracks, aging, rat bite damage and other phenomena should be replaced in time;
The hose can not be used for more than two years.
