摘要

FIELD: construction.SUBSTANCE: heat-insulating pipeline coating includes at least one layer of heat insulation made from tightly united styrofoam segments fixed on the pipeline surface using steel galvanized bandage tapes so that at least two bandage tapes are arranged on each segment. A bitumen-polymer tape is applied on top of the styrofoam segments. On top of the bitumen-polymer tape a protective shell from rock shields is arranged, which are fixed on the pipeline surface using bandage tapes so that at least two bandage tapes are installed on each rock shield.EFFECT: increasing the durability and lifetime of the pipeline.7 cl, 1 dwg
