Abstract
The utility model provides a novel steel pipe spare of three -layer polypropylene outer anti -corrosion coating belongs to anticorrosive pipeline technical field, aims at solving present anticorrosive pipe fitting non -corrosibility and can poor, not be suitable for the practical problem who matches and link with anticorrosive pipeline. The steel pipe spare body outside that it adopted there is the epoxy powder layer by the static sprayed coating, and there is the adhesive phase epoxy powder layer outside by electrostatic spraying, and there is polypropylene PP surface course the adhesive phase outside by the static system of spouting. The three -layer polypropylene outer anti -corrosion coating that epoxy powder layer wherein, adhesive phase, polypropylene surface course are constituteed. Its simple structure is practical, and the non -corrosibility can be good, and anti external force is strikeed and the damage resistant, is applicable to the anticorrosion pipeline of trades such as oil, petrochemical industry, the natural gas.
Description
Technical field
The utility model belongs to a kind of steel corrosion pipe fitting in anticorrosion conveyance conduit technical field.
