Abstract
The invention discloses an anti-collision outer coating for a pipeline, and belongs to the technical field of ocean engineering. The pipeline outer coating comprises a pipeline outer coating body used for covering the pipeline and a flange outer coating used for covering a pipeline connecting flange; the pipeline outer coating body comprises a corrugated pipe arranged on the periphery of the pipeline in a surrounding mode and a balance weight layer covering the periphery of the corrugated pipe; the flange outer coating comprises a tubular mold annularly arranged on the periphery of the flange, and the two ends of the tubular mold extend to the balance weight layer and are fixedly connected with the balance weight layer; and porous metal is arranged between the tubular mold and the flange and between the corrugated pipe and the pipeline in a filling mode. According to the anti-collision outer coating for the pipeline, the anti-collision performance of the pipeline and the flange is enhanced by arranging the porous metal filling layer in a covering mode, the problems of fixation, sealing, water prevention and the like caused by arranging the porous metal filling layer in a covering mode are solved, meanwhile, the construction technology is simple, and installation is easy and fast.
Description
technical field [0001] The invention relates to a pipeline anti-collision outer cladding structure, which belongs to the technical field of marine engineering. Background technique [0002] At present, pipelines are inevitably affected by single or multiple lateral impact disasters in the working environment, such as impact loads such as falling objects on offshore platforms, anchoring ships, or rolling rocks on the seabed. These impact loads may cause pipelines and The rupture or penetration of the flange connection section will cause serious ecological and economic accidents such as pipeline leakage, combustion or even explosion. [0003] In order to solve the above problems and prevent damage caused by impact loads, pipes and their flanges are usually coated with impact-resistant and energy-absorbing materials on the outer layer, or specially installed protective brackets or covered with concrete briquettes and other anti-impact structures to absorb and dissipate large P...
