Abstract

The invention discloses a metering oil pipe for the petrochemical industry and a preparation method thereof. The metering oil pipe comprises a composite barrier layer, a first antistatic plastic layer, a fiber-reinforced explosion-proof layer and a second antistatic plastic layer which are sequentially arranged from inside to outside. The composite barrier layer comprises a low-permeability barrier layer, a reinforced barrier layer and a bonding layer, wherein the low-permeability barrier layer and the reinforced barrier layer are distributed from inside and outside, and the bonding layer is located between the low-permeability barrier layer and the reinforced barrier layer. The metering oil pipe has the advantages that through internal and external interaction among the different materiallayers, the overall barrier performance and environmental protection performance are remarkably improved; the metering oil pipe has excellent antistatic properties and comprehensive mechanical properties, such as resistance to buckling, stretching, compression, explosion and the like, and can be widely applied to the fields of oil delivery and transportation, automotive fuel systems and the like.

Description

technical field [0001] The invention relates to an oil pipe for petrochemical industry, in particular to a metering oil pipe for petrochemical industry and a preparation method thereof. Background technique [0002] With the enhancement of people's awareness of environmental protection and the strict implementation of environmental protection laws, environmental protection has covered the prevention and control of air, water, soil, noise and other aspects. Especially the air pollution, whether it is particulate matter such as PM2.5, nitrogen oxides, hydrocarbons, or carbon monoxide, will increase with the increase of sulfur content. Fuel oil pollution is an important source of pollution, which has received more and more attention. [0003] Fuel pollution comes from two aspects. On the one hand, the sulfur content in fuel oil is an important source of air pollution; on the other hand, the leakage and volatilization of fuel oil are also important reasons for the increase of ...
