Thermal spraying has been widely used in the oil industry, has been successfully used in oil exploration,mining and other equipment repair and protection.which has been successfully used for petroleum pipe thermal spraying, anticorrosive technology of offshore platform. The introduction of arc in Shengli oilfield downhole engineering installation company spraying, solve the problem of metal corrosion,fill the corrosion of metal. Blank oil oil used in all kinds of pump piston, cylinder, impeller and other parts can be used to repair and strengthen a variety of thermal spraying methods. Using oil tower, tank, pipe can be arc spraying aluminum,zinc, stainless steel coating or by flame spray corrosion in Huangdao and Qinhuangdao oil depot.The company's first stop outside the tank surface using this kind of thermal spraying technology. By plasma spraying, flame spraying, arc spraying can be solved by various oil boiler pipeline corrosion and erosion America. Texas and Luis Anna oil derrick, sea oil spray zinc, plus two vinyl aluminum paint sprayed aluminum and aluminum paint 0.16mm, ethylene, after 25 years after the inspection, the coating is good. The British Beihai drilling platform by spraying aluminum coating and sealing technology, long-term operation of anti-corrosion effect is good.

In recent years, with the great progress of thermal spraying technology and the rapid development of nanotechnology, the combination of thermal spraying is becoming an important field of thermal spraying technology development of nanostructured coatings. At present, the use of Thermal Sprayed Nanostructured Coatings prepared mainly by 2 ways: (1) the preparation of macro coating nano features. Nanoparticles is relatively less content into traditional coating, the coating becomes the nano particle dispersion strengthening, has certain characteristics of the nano composite coating; (2) coating preparation completely composed of nano particles, gives the engineering performance of coating with excellent. The composite powder AT13 powder doped with nanometer particles Al2O3 13wt%TiO2 of plasma spraying and its application in gas well tubing in the experiment. The experimental results show that the performance of tile powder doped nanometer particle, coating uniformity. High; nano particles made the coating residual stress decreases; coating microstructure than the conventional coating doped nano particles in similar conditions, the hardness, lower friction coefficient and wear resistance increased by more than 30%, which makes the oil pipe corrosion resistance is improved by nearly 1 times.

In solving the problem of petroleum and natural gas industries in corrosion and wear problems of various types of technology, thermal spraying technology has been proved to be a very effective and successful technique used in natural gas pipeline has also made some achievements, and accumulated experience, laid a good technical foundation for its further application. But the current domestic thermal spraying technology has a large gap compared with foreign countries, the application of process stability is not high, the low level of professional operators, equipment shortage, development ability is weak, the porosity of the coating is high, poor performance and compatibility issues closed paint and so on.To solve these problems,and take the following measures:

1. according to the national advocacy of knowledge innovation and the upgrading of industrial policy, carried out joint research, development of new thermal spraying technology, nano coatings and other new technology, and the establishment of test results, pilot scale and Industry Application of one-stop product innovation and development system;

2. a complete development and supporting technology system, including pretreatment,coating materials, thermal spraying coating and sealing, operator training, the establishment of professional technical support and service team construction;

3. the concepts and methods of engineering equipment life cycle cost assessment based on the oil and gas industry and promotion, in order to truly reflect and realize the thermal spraying technology cost advantage, and promote its natural gas pipeline in the comprehensive promotion and application.
