For the medium duty coating, construction of the first step is to remove rust. A high quality coating depends on a thorough rust, so it usually uses blasting abrasive to blast, exposing metallic luster and removing all rust and grease. For site construction manual rust coating is available. The coating selected must consider the surrounding environment, different coatings for different etching conditions have different tolerance.

According to the different needs, you can choose polyvinyl chloride coated (PVC), polyethylene (PE), epoxy resin (EPOZY), and other various properties of coatings, with the advantages of good adhesion, corrosion resistance, can be resistant to acid, alkali and other chemical corrosion, non-toxic, does not rust, abrasion resistance, impact resistance, permeability, pipe surface smooth, does not adhere to any substance, can reduce transmission resistance, increase transportation efficiency and reduce delivery pressure loss. Coating is free of solvent, no leaking substances, and therefore does not pollute the transport medium, thus ensuring the purity of the fluid, in the range of -40 ℃ to + 80 ℃ thermal cycling can be used interchangeably, no aging, no cracks, which can be used in cold climates and other harsh environments.

Due to corrosion of steel is an uneven damage, and once it occurs on the surface of the steel structure, the corrosion happens rapidly to make steel stress concentration, and stress concentration phenomenon will accelerate the corrosion of steel, which is a kind of vicious circle of steel corrosion. The corrosion makes the anti-cold crisp properties of steel fall, as well as the fatigue strength. There will be certain thinning phenomena in the natural environment.
