PIPELINE EXPANSION LOOP MAKING METHOD

摘要

FIELD: construction engineering; making of pipeline. SUBSTANCE: pipe is curved to required shape and flanges are connected to pipe. Then woven tubular casing is fitted on pipe. Ends of casing are secured on flanges, then casing is impregnated with binder and consolidated. Corrugated plastic pipe is used. Prior to forming outer load-bearing layer of expansion loop, outer grooves of corrugated pipe are filled by winding-on reinforcement threads impregnated with binder. EFFECT: improved reliability of pipeline. 3 cl
