OVER GROUND PIPELINE OF INCREASED RELIABILITY

摘要

FIELD: machine building. ^ SUBSTANCE: pipeline is assembled on regulated supports with device whereon pipes lay. The supports are connected to a foundation plate positioned without embedding on a levelled base with a sliding layer. In spans between supports the pipeline is additionally equipped with trussed poles; while on the supports it is equipped with damping devices in form of removable structures secured to the pipeline by means of yokes with pads. A truss pole is formed with four metal trusses arranged along the pipeline and preliminary stressed by means of screw braces in the middle of a span in mutually perpendicular directions relative to axis of the pipeline. Also, ends of four stressed metal trusses are fixed with yokes arranged on the pipeline between the spans. The screw braces with their one end are attached to a yoke in the middle of a span, while with their other end they are attached to stressed metal truss. ^ EFFECT: raised reliability of over ground pipelines operation, their protection from wind loads and prevention of wind vibrations. ^ 4 dwg
