Solution of double-layer composite oil pipeline in gas station
Solution of double-layer composite oil pipeline in gas station

Corrosion resistance: HDPE material itself has strong corrosion resistance and rust. It is especially used in areas with strong soil corrosivity and high humidity. It has obvious advantages compared with the characteristics that steel pipes are easy to be corroded and rusted.

Strong pressure bearing capacity: the pipeline system of Aiyuan gas station can continuously and safely transport fluid with a pressure of 10 bar, which is equivalent to the seamless steel pipe currently used in the gas station, which is more than twice the actual * oil transmission pressure of the gas station. The instantaneous pressure bearing capacity of the pipeline system of Aiyuan gas station exceeds 30 bar and the burst pressure is 45 bar.

Tough and reliable: the tough and flexible structure of high-density polyethylene material makes the pipeline system of Aiyuan gas station have strong compression resistance, impact resistance, puncture resistance, tensile resistance and ground motion resistance. The pipeline system of Aiyuan gas station can be stretched 6 times without fracture, which can effectively resist the effect of in-situ stress without affecting the tightness of various connecting parts due to ground motion, so as to ensure the safety and reliability of the pipeline system of the gas station.

Long service life: the service life of HDPE material can reach 50 years after laboratory test; The service life of steel pipe mainly depends on the influence of soil on its anti-corrosion coating, ranging from 5-10 years to 20-30 years.

Effective elimination of static electricity: the unique electrostatic conductive coating of the pipeline system of Aiyuan fuel station can eliminate static electricity while the fluid in the pipe flows. This performance has been tested and fully conforms to the relevant German regulations on the elimination of static electricity of combustible liquids.

Safe installation: compared with steel pipes, the welding of the pipeline system of Aiyuan gas station does not need hot work, but only needs a special intelligent welding machine. The pipeline system of Aiyuan gas station does not need to be treated. With the patented technology of wohong company, even the connection of double-layer pipeline can be completed at one time, and the pipeline can be directly buried after connection. It takes 3 to 5 days to complete the pipeline installation of an ordinary gas station. The use of seamless steel pipe requires anti-corrosion treatment of no less than the reinforced grade, electric welding and burying in the reserved pipe trench, but the use of seamless steel pipe takes about 15 days.

Wide application range: the pipeline system of Aiyuan gas station can work normally in the range of soil temperature - 40 º c-50 º C, which is suitable for most areas.

Extremely low pipeline permeability: under stable room temperature conditions, the total amount of hydrocarbon steam penetrated from the pipe wall of Aiyuan oil pipeline per square meter per day is 0 when the fluid in the pipe is gasoline with octane number of 98; It's 15% methanol

0.03 g when mixed with 85% petroleum. The standards formulated by UL / ULC and IP are 4G / m2 / day and 2G / m2 / day respectively.

Double protection: the pipeline system of Aiyuan gas station adopts the coaxial "pipe in pipe" structure. The interior is the low leakage oil transmission pipeline, and the exterior is the protective sleeve to prevent the internal pipeline from being affected by the outside and prevent leakage again.

All-weather monitoring: in order to ensure safety, Aiyuan fuel pipe can also be equipped with a leakage detector to monitor the pipeline all-weather. Once a leakage is found, the oil delivery system will be closed automatically.
