Abstract
Description
technical field
[0001] The invention relates to a processing method for an outer anti-corrosion layer of a steel elbow, in particular to a processing method for a three-layer PE outer anti-corrosion layer of a single steel elbow. Background technique
[0002] At present, the known processing method of the outer anti-corrosion layer of the steel elbow is: after a plurality of steel elbows are derusted and qualified, they are sequentially connected end to end according to their axis directions to form a plane opening circular ring, and the elbow ring Placed horizontally on the circular transmission track, the electric induction heating, epoxy powder coating, composite belt winding, anti-corrosion layer rolling, anti-corrosion layer secondary heating, and anti-corrosion layer secondary rolling are arranged in sequence on the circular axis of the elbow circle. Pressing and water cooling each anti-corrosion forming process, and the components of each forming process corresponding...
