Anti-corrosion rigid waterproofing casing, mainly made of high-quality seamless steel tubes for can effectively prevent the corrosion of the medium in the pipeline damage caused by the leakage after, protect the pipes.
Rigid waterproofing casing mainly adopts national super seamless steel tube as a raw material for production, generally USES the embedded type installation to install, the use of waterproof casing decide waterproof casing other pipe products than in the past, the use of time longer, general can keep on more than 20 years. But if pipe flows through the corrosive medium, may cause corrosion to pipe, according to the severity of the corrosion, can cause all kinds of unsafe hidden trouble, especially in pipeline crossing shear walls or buildings when the hidden trouble will be more obvious, so let's set up in this special place rigid waterproofing casing to protect the pipes. Anticorrosion rigid waterproofing casing with internal coating spraying PTFE materials, can effectively deal with various chemical, oil medium corrosion.
Rigid waterproofing casing anticorrosive processing methods:
1, clean
Using solvent, emulsion steel surface cleaning, to remove oil, dirt, lubricant, and similar organic matter, but it cannot remove rust, scale, etc on the surface of the steel, so only as auxiliary means in the anti-corrosion production.
2, Using tools to clean
Main USES steel wire brush tool for steel surfaces such as grinding, can remove loose or cock scale, rust, slag, etc.If the solid iron oxide adhered on the surface of the steel, tool cleaning effect is not ideal, anchor pattern depth of anticorrosion construction requirements.
3, pickling
Commonly used chemical and electrolytic pickling process, two methods do use only pipeline anticorrosion chemical pickling, can remove scale, rust, old coating, sometimes can be used as sandblasting derusting after reprocessing.
4, shot derusting spray (left)
Spray (cast) shot derusting spray is driven by high-power motor (cast) shoot high-speed rotating blades, make steel grit, steel shot, segment, minerals and other abrasive wire under the action of centrifugal force on steel pipe surface spray (cast) processing, not only can thoroughly remove rust, oxides and dirt, and steel pipe under the action of abrasive violent impact and friction, also can achieve the required uniform roughness.
