FIELD: process engineering.
SUBSTANCE: proposed method of making combined article or combined pipe comprising inner sealing polyolefin layer and outer load-bearing composite layer includes application of composite layer on polyolefin workpiece outer surface and setting bonder in composite polymer layer. It differs from known methods in that chemically active nanolayer is applied by plasmachemical process on polyolefin workpiece surface between sealing and load bearing layer to bring about cross-linkage between macromolecules of binder and polyolefin at the their interface. Plasma forming gas represents mix of air with vapors of toluene or mix of oxygen with acetylene.
EFFECT: longer life, simplified process.
