PROCESS OF MANUFACTURING POLYETHYLENE TUBE REINFORCED WITH METAL FRAME

摘要

FIELD: production of polyethylene tubes. SUBSTANCE: process includes positioning of longitudinal metal fitting on mandrel, winding of lateral fitting on it with specified spacing, fixing of fittings in crossing points, formation of polyethylene sheath and division of continuous tube into sections of measured length. Winding at start and finish of measured length is conducted with spacing of t1 between turns which value meets relationship , where d is diameter of lateral fitting that is followed by threading on these sections. EFFECT: reduced labor input and saving of consumable materials. 1 cl, 2 dwg
