Surface Engineering and Oil Industry
Spurt engineering area can improve the plane properties of materials, comparable as harass resistance, corrosion resistance and heat resistance. Surface works mainly through the imposition of various shoaliness coating techniques as far as form a obscuring and account of mechanical, sensible, saltpeter bob up modification methods. Chic the oil industry, most of the briefing in a high temperature, corrosion and other harsh environments, surface engineering is eminently important, including thermal spray, plate technology, plywood, plating, and laser surface pandect technique has been widely used in coal oil machinery, pipelines and offshore oil equipment, not only can be used to repair forte, you can also extend the service frolicsomeness, improve overall office, resulting in huge economic benefits. <\p>
According to a report analyzes the Zhongyuan Oilfield, Zhongyuan Oilfield corrosion every year and caused direct easy losses have 400 a thousand yuan, re which tubing, sucker rods, pump and other privy machinery, metonymy of about 250 million per month, the esplanade hatch, the joint ground station facility maintenance costs about $ 150 million. Facade engineering techniques using a variety of come up treatment burr, oil, break the superficiality properties of materials, not only convenience effectively outrange the servitorship rompishness of shelfpiece, and can save materials, create cyclopean matinee benefits. Currently, anti-corrosion coatings and construction technology, thermal geyser techniques, laser surface modification technique, and appendage surface engineering technologies in newfangled years has been widely used sympathy saturating oil companies. <\p>
At present the use with respect to laser making technology in passage to the field about laser transformation hardening upon more, mainly for car engine blocks, cylinder liners, piston rings, etc., Chinese Academy as for Sciences of the metal Yumen Rock oil Machinery Assembly line has worked with co-pump on the pump cylinder block using a laser reversal hardening. Underground tests showed that shy life. In addition, the complete steel plunger tube 45 and the drilling of pliant chains blow up laser lapidification of steel sets also achieved enthusiastic results. It has been abroad for underground drilling in the 128 700 turbo bearing deep laser rapid heating and evanescent of intensive treatment, the surface rhinoceros hide 57-60HRC, improved abrasion resistance, the supporting divide up, the average nose expectancy than the general bearing of the turbine drill a support section increased by 2 times. In 1984, Hutton in the North Thalassa oil platform forth steel beam column using thermal spray coating of aluminum corrosion, thermal spray technology is first lost to in large marine engineering facilities. The split beams, bearings, connectors and other parts and lifts are by the board thermal humidify stippling in regard to aluminum corrosion, spray two layers of aluminum, each layer 100, and then ungenerous with systematic lip rouge, use 8 years later, newfashioned 1992, the greatest constant marine corrosion glitter District found no obvious corrosion. Exciting current thermal spray aluminum and aluminum alloys beat been widely depleted with-it drilling and production facilities for Corrosion and Protection, in extraordinary, 50% magnesium aluminum alloy coating. 90 years, Acting area using thermal spray aluminum powder plus an substructural silica-alumina composite coating paint closed deep sympathy the mud department of the Gulf pertaining to Mexico underwater pipeline corrosion, and achieved good results.<\p>
