Spiral pipe cleaning method

Spiral pipe cleaning method


Cleaning method of spiral steel pipe. Cleaning: the application of solvents, emulsions to clean the appearance of steel to reach the removal of oil, grease, dust, smoothing agent and similar organic matter, but it can not remove the appearance of steel rust, oxide, welding, etc., and thus in the production of anti-corrosion As a covert trick.
Something rust: the first use of wire brush and other things on the steel surface grinding, you can remove the loose or tilt of the oxide, rust, welding slag and so on. Hand tools to reach the Sa2 level, the power of rust can reach the Sa3 level, if the steel surface attached to the solid iron oxide skin, rust-free results do not think about, not up to the requirements of anti-corrosion construction of the depth of the anchor.
Pickling: General use of chemical and electrolytic two ways to do pickling treatment, pipeline corrosion only chemical pickling, you can remove the oxide, rust, the old coating, and sometimes can be used as a blasting after the re-disposal. Chemical cleaning, of course, can make the appearance of the inevitable degree of cleanliness and roughness, but the anchor is shallow, and easy to form pollution.
Spray (throw) shot rust: spray (throw) is the high-power motor driven by spray (throw) to shoot high-speed rotation of the blade, so that steel sand, steel balls, wire segments, minerals and other abrasive in the centrifugal effect of steel The appearance of the spray (throw) shot disposal, not only can completely eliminate the rust, oxides and dirt, and the steel pipe in the abrasive impact and friction effect, but also to achieve the required average roughness.
