PIPELINE LINK MADE BY EXTRUSION OF POLYETHYLENE PLASTIC AND METHOD OF JOINING FUNNEL PRODUCTION

摘要

FIELD: polyethylene pipes production. SUBSTANCE: pipeline link made by extrusion of polyethylene plastic has formed on it joining funnel. Formed by extrusion link of pipeline has wall thickness exceeding 5 mm. Formed on pipeline link joining funnel has approximately similar thickness of wall. Cross-section of wall has highly crystalline inner area and low crystalline outer area. Highly crystalline inner area forms going along circumference crystalline arch. It is determined for practically free from deformations resting of low crystalline outer area during arising shrinking strains. Method of the pipeline link production is described. EFFECT: improved process.
