Description

A kind of seamless steel pipe internal wall cleaning
Technical field
The present invention relates to a kind of seamless steel pipe internal wall cleaning.
Background technology
Ammonia is one of cold-producing medium of using always, is usually used in large-scale refrigeration plant, after the ammonia steam that evaporimeter flows out is getting into compressor; Along with the constantly past compound compression of compressor, internal pressure raises gradually, finally forces ammonia steam generation liquefaction reaction; Be accompanied by a large amount of exothermic phenomenon in this process, for the temperature that guarantees liquid ammonia is unlikely to too high, this liquid ammonia gets into condenser immediately and cools off; The seamless steel pipe of delivering liquid ammonia is being born important conveying task; Therefore the surface treatment of steel pipe inwall is extremely important, and for the seamless steel pipe internal wall cleaning, the common practice of existing market is:
1, common cleaning:
Utilize solvent, emulsion to clean steel surface, remove oil, grease, dust, lubricant and similar organic matter, but it can not remove the rust, oxide skin, welding agent of steel surface etc. to reach, therefore in anticorrosion production as supplementary means.
2, instrument rust cleaning:
The main instrument such as wire brush that uses is polished to steel surface, can remove the oxide skin, iron rust, welding slag of loosening or perk etc.The hand-operated tools rust cleaning can reach the Sa2 level, and powertool cleaning can reach the Sa3 level, if the iron scale of steel surface adhesion-tight, instrument rust cleaning effect is undesirable, does not reach the depth of abrasion pattern of anticorrosive construction requirement.
3, pickling
General do pickling processes with chemical and two kinds of methods of electrolysis, chemical pickling is only adopted in pipeline corrosion protection, can scale removal, iron rust, old coating, and available sometimes its processing again after as derusting by sandblasting.Though Chemical cleaning can make the surface reach certain cleannes and roughness, its anchor line is shallow, and is prone to environment is polluted.
4, rust cleaning is penetrated in spray (throwing):
It is to penetrate blade through heavy-duty motor drive spray (throwing) to rotate at a high speed that rust cleaning is penetrated in spray (throwing); Make abrasive materials such as steel sand, shot, wire shorts, mineral matter under centrifugal action, spray (throwing) and penetrate processing steel tube surface; Not only can thoroughly remove iron rust, oxide and dirt; And steel pipe can also reach needed even roughness degree under the fierce effect of impacting with friction of abrasive material, but adopts spray (throwing) to penetrate to eliminate rust cost higher; Employ a large amount of machinery equipments and manpower and materials, cause the waste of resource.
