Anti rust process

Steel surface treatment is mainly anti rust, the following is anti rust process:

3-Layer Polyethylene Coating System

First step is to clean, use cleaning solvent emulsion cleaning the steel surface, in order to achieve the removal of oil, grease, dust, lubricants and similar organic matter, but it can not remove the steel surface rust, oxide, solder medicine.

Second step is to right tools rust, rust tools you want to have to use a wire brush, wire brush to remove loose or warped oxide, rust and slag. To achieve the desired effect of the rust, the hardness of the steel surface must be based on the original extent of corrosion and the required surface roughness, coating, etc. to select the type of abrasive, the epoxy layer, two or three layers polyethylene coating, using mixed abrasive grit and steel shot blasting easier to achieve the desired effect.

Third step is to do pickling, chemical and electrolytic pickling generally use two methods, using only chemical pickling pipeline corrosion. Although chemical cleaning can achieve a certain surface cleanliness and roughness, but there are some pollution to the environment.

Finally emphasis on the importance of surface treatment in the production, strictly control the process parameters when anti rust.

Electrical resistance welding

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.

Galvanized pipe process characteristics

What is Galvanized Steel Pipe? Galvanized steel can be made into a strong plumbing or tubing material -- one that resists corrosion from exposure to water or the elements. It has been used used for water-supply pipes or as a strong tubing for outdoor applications.
