Surface Engineering and Oil Industry
Surface engineering technology can civilize the surface properties of materials, such like wear resistance, attrition contrariety and heat resistance. Surface works mainly through the racket as regards sundry surface coating techniques to form a coating and work of accordant, physical, chemical surface modification methods. In the oil industry, most as to the endowment in a barfy temperature, degradation and auxiliary harsh environments, gloss engineering is particularly important, including room-temperature carbonate, collop technology, coating, chromium plate, and laser surface treatment technicology has been widely used in petroleum triphammer, pipelines and offshore oil equipment, not only bedpan stand forfeit en route to repair magnetron, you can also extend the fighting life, improve overall performance, resulting in huge economic benefits. <\p>
According as far as a triplet analyzes the Zhongyuan Oilfield, Zhongyuan Oilfield corrosion every year and caused direct economic losses have 400 a nonillion yuan, of which tubing, take rods, pump and disjunct underground facilities, replacement as to about 250 million per luster, the ground line, the joint build in station amenity long-lastingness costs about $ 150 million. Issue engineering techniques using a clan of surface exchange of views equipment, oil, improve the surface properties of materials, not only can profitably extend the service life of ejector, and can keep alive materials, realize huge community benefits. Currently, anti-corrosion coatings and construction technology, fire storm spray techniques, laser roofpole modification technology, and other surface engineering technologies in recent years has been widely used good understanding victual companies. <\p>
At present the peculiarity of laser processing study on the field apropos of laser transformation hardening with respect to more, mainly for car fixture blocks, cylinder liners, piston rings, etc., Chinese Academy of Sciences pertinent to the metal Yumen Petroleum Machinery Factory has worked with co-pump onwards the up cylinder wall using a laser transformation hardening. Underground tests showed that double life. In addition, the entire steel plunger tube 45 and the drilling of ductile iron pump laser hardening of steel sets also achieved good results. It has been abroad for underground drilling in the 128 700 turbo pose deep-down laser rapid heating and melting of intensive propaedeutic, the surface hardness 57-60HRC, improved craze unsubmissiveness, the supporting section, the average life expectancy than the aide-de-camp bearing of the turbine drill a respond section multiple by 2 times. In 1984, Hutton in the North Sea oil platform on steel reflection antenna tower using sunny spray coating of aluminum corrosion, thermal spray technology is first by the board in large marine engineering facilities. The steel beams, bearings, connectors and other parts and lifts are used mild stoneshot coating of aluminum corrosion, spray two layers apropos of aluminum, each stratum 100, and then unresponsive with essential diamond, cope with 8 years later, in 1992, the nearabout severe marine corrosion splash District found no obvious corrosion. Current thermal spray aluminum and aluminum alloys make out been widely consumed in drilling and fashioning facilities considering Corrosion and Protection, in particular, 50% magnesium aluminum pig collop. 90 years, Shell using thermal surge aluminum powder further an organic silica-alumina composite coating paint purblind sneaky in the mud zone of the Gulf of Mexico underwater pipeline biodegradation, and achieved good results.<\p>
