Anti-corrosion coatings play an “armor†role in the oil industry. Steel structure equipment, offshore drilling platforms, and transport vessels in the oil industry all require anti-corrosive coatings to “wear†protective clothing. In recent years, the demand for anti-corrosion coatings in China has grown rapidly. In 2006, the output was approximately 1.22 million tons, becoming the second coating product with a production volume of over one million tons, and its share has also increased from 17.6% in 2005 to 21.6%. This rapid growth is inextricably linked with the rapid development of the oil industry. This is the information that the reporter obtained from the Fourth International Symposium on Anticorrosion Coatings and Offshore Oil Industry Anticorrosion Technology held in Beijing on July 3.
With the rapid development of China's oil industry, the corrosion protection of various crude oil extraction, transportation, and storage equipment is becoming more and more important. China's anti-corrosion coating industry is expected to usher in faster and better development opportunities. According to reports, a series of petroleum industry projects that have been started and are about to start soon will provide a better platform for the development of anti-corrosion coatings.
At present, China has a large number of offshore oil platforms and corresponding transportation vessels and submarine pipelines. The discovery of Nanpu Oilfield means that the demand for China's COOEC platforms will double, and the demand for COOEC anti-corrosion coatings will also increase substantially. In addition, after the first West-East Gas Pipeline Project was completed and put into operation, the State Council also proposed the launch of the second West-East Gas Pipeline and land-entry oil and gas pipelines and other key energy projects at the end of 2006. A large number of steel oil and gas pipelines were used as anti-corrosion coatings. Provide another stage to show your skills. Experts predict that the first phase of the National Petroleum Strategic Reserve Plan, which will be completed by the end of next year, can bring 200 million to 400 million yuan in market demand for anti-corrosion coatings, and the second phase of the project can bring 450 to 600 million yuan in anti-corrosion coatings. Market demand.
It is understood that most of the offshore oil platforms are steel structures, and their environment is complex. They are eroded by different media such as seawater, salt fog, and wind and rain. Different parts have different emphasis on corrosion protection, and there are strict restrictions on the raw materials, construction environment, and technical conditions of anticorrosion coatings. At present, PetroChina's steel platform in Bohai Bay's atmospheric region has mostly epoxy primers and intermediate coatings for epoxy primers, multiple polyurethanes for topcoats, and steel platforms for tidal range, epoxy primers for topcoats and topcoats, and topcoat thicknesses. greatly increase. The anti-corrosion of the inner wall of oil and gas pipelines is mainly due to the chemical and electrochemical corrosion caused by corrosive media (moisture, sulfides, chlorides, oxides, etc.); the anti-corrosion of the outer wall is complex, requiring high resistivity of the outer coating and resistance to cathodic disbondment. Good, resistant to chemical media, resistant to microbial corrosion, currently used in asphalt (petroleum, coal tar, epoxy asphalt), epoxy (powder, liquid coating), PE (extrusion PE and PE tape) 3 types of materials, Different environments to choose to apply. In addition, the state clearly stipulates that anti-corrosion must be applied to the inner wall of petroleum storage tanks, and the matching coating and thickness of different oils must be different. In particular, there is a difference in the resistance to oil penetration and corrosion resistance of the coating. Since the solvent resistance and corrosion resistance of the inner wall coating depends on the basic properties of the coating film-forming substance, high cross-linked epoxy or phenolic modified anti-corrosion coatings are generally selected.
According to expert analysis, although China's anti-corrosion coating market has great potential for development, domestic products have a considerable distance from the international advanced level in terms of technical content, coating technology and related standards. In the field of high-end heavy anti-corrosion coatings, it is basically monopolized by foreign-invested companies such as British International Paint, Jordan, Norway, Denmark, Haihong elderly, Dutch Macalon, and Nippon State. Experts believe that the standardization of the domestic anti-corrosion coating industry needs to be improved. In the future, the development of anti-corrosion coatings will tend to be environmentally friendly, energy-saving, and functional. Research on construction performance and coating technology should be strengthened, and construction techniques should be formulated for different substrates and environments.
According to another report, the Coatings and Coatings Special Committee of the China Chemical Society is actively preparing for the establishment of the Marine Oil Anti-corrosion Sub-committee, which is expected to build a new platform for the development of anti-corrosion coatings in China.
