STEEL PIPE COATED WITH A CURED OLEFINIC THERMOPLASTIC ELASTOMER

摘要

The invention relates to a coated steel pipe which can be used in severe environmental conditions, and which has excellent heat resistance and impact resistance at low temperatures. This is achieved by means of a steel pipe that is coated with a cured olefinic thermoplastic elastomer via denatured polyolefins on the surface-pretreated outer surface, said elastomer being produced from a mixture containing between 15 and 38 wt.% ethylene-α-olefin-non-conjugated polyene copolymer rubber (A) from ethylene, one or more α-olefins of a carbon number of between 3 and 20 and one or more non-conjugated polyenes, between 85 and 62 wt.% polypropylene resin (B) [the total amount of the components (A) and (B) being 100 wt.%] and between 0.05 and 10 wt.% curing agent (C).
