Buried antistatic flame-retardant composition petroleum pipeline

Abstract

The invention discloses a buried antistatic flame-retardant composition petroleum pipeline which comprises an inner PE (polyethylene) antistatic layer, an inner binding agent layer, a barrier layer, an outer binding agent layer and a PE protection layer. The inner binding agent layer is arranged outside the PE antistatic layer, the barrier layer is arranged outside the inner binding agent layer, the outer binding agent layer is arranged outside the barrier layer, the PE protection layer is arranged outside the outer binding agent layer, the wall thickness of the PE antistatic layer is at least 0.5mm, the wall thickness of the inner binding agent layer is at least 0.2mm, the wall thickness of the barrier layer is at least 0.5-1.2mm, and the wall thickness of the outer binding agent layer is at least 0.2mm. The petroleum pipeline is applicable to transportation of electrically-conducted combustible liquid media through buried petroleum pipelines, and combustion and explosion of combustible liquid caused by static electricity can be avoided.

Description

technical field [0001] The invention relates to an underground antistatic and flame retardant composite petroleum pipeline. Background technique [0002] At present, anti-corrosion pipelines have been widely used in important industrial production departments such as chemical industry, petrochemical industry, metallurgy, nuclear energy and military industry to transport corrosive liquid media. Most of the existing anti-corrosion pipelines with non-metallic lining do not have anti-static function. If oil or other non-conductive liquid medium is transported, the friction between the two will generate static electricity, which is easy to cause explosion and has serious accident hazards. Contents of the invention [0003] The object of the present invention is to provide a buried antistatic and flame retardant composite petroleum pipeline aiming at the defects existing in the prior art. [0004] In order to achieve the above object, the present invention adopts the following ...
