Description

A kind of long range surface treatment of inner wall of steel pipe and coated lining anti-corrosion method
Technical field
The present invention relates to a kind of inner wall of steel pipe of trandfer fluid surface treatment and coated lining anti-corrosion methods over long distances, especially It is long range surface treatment and the coated lining anti-corrosion method of a kind of inner wall of steel pipe.
Background technique
Using steel pipe trandfer fluid, be it is most safe, most convenient is also a kind of most cheap delivery method, according to conveying The differences such as type, concentration, temperature, flow velocity, the pressure of medium can generate different degrees of corrosion, wear and knot to inner wall of the pipe Dirt is extremely limited the application of pipeline.Anti-corrosion material and construction technology are to extend the pipeline longevity in reasonable selection pipeline Life reduces the effective method of whereabouts such as invest and extend manufacture cycle.In numerous pipeline internal corrosion techniques, anticorrosive paint is with it It is low cost, wide in variety, use the wide inner wall anti-corrosive for being widely used in various pipelines.
Domestic pipeline inner side anticorrosion coating coated technique is using single prefabricated anti-corrosion method at present.I.e. in every root canal road It is installed again after wall derusting anti-corrosive, the effect of high temperature, is not only burned the erosion resistant coating of commissure, and near weld seam when welding The quality of erosion resistant coating be also influenced to different extents.Since pipeline internal corrosion layer commissure repaired mouth difficulty is larger, and welding slag The many factors such as limitation of overlap and commissure derusting, make the mouthpiece quality of erosion resistant coating at weld bond it is difficult to ensure that, this just makes After putting into operation at pipeline, the interior erosion resistant coating of commissure coating falls off in a short period of time, makes the steel pipe inner wall of commissure naked It is run under dewiness state.Concentration of the corrosion factor in commissure in inner wall of the pipe medium is corroded, and accelerates corrosion rate at this, mistake Early appearance pipeline is in commissure because the reason of internal corrosion perforates.Seek completely continuous anticorrosion technology, is to solve the problems, such as this Unique method.Inner wall of the pipe coated lining anticorrosion process online over long distances can guarantee that inner wall of the pipe obtains completely continuous anti-corrosion and applies Layer.Anticorrosive paint is the matter of utmost importance that must be solved in the surface treatment of coated lining preceding pipeline inner wall.
Summary of the invention
The purpose of the present invention is to provide a kind of surface treatment of the long range of inner wall of steel pipe and coated lining anti-corrosion methods, originally Invention can guarantee all to install in steel pipe and after pressure testing, cleaning, de- tumor deburring, derusting by sandblasting in inner wall of the pipe table Once online coated lining is completed with pipeline internal corrosion, can not only remains in peace and quiet pipeline, remove welding slag at inner wall of the pipe weld bond The derusting standard that overlap, derusting by sandblasting make inner wall of the pipe reach Sa2.5 grades or more, and make inner wall of the pipe that there are 40 μm or more Roughness, and make inner wall of the pipe obtain it is continuous it is uniform there is certain thickness interior anti-corrosion to apply lining, guarantee that rotten coating is viscous Knot power is strong, and the effective service life for extending pipeline inner wall anti-corrosive coating, work efficiency is high.
