Recently, the international standard ISO 24565 "Ceramic Lined Tubing for Petroleum and Natural Gas Industry", which was developed by the Engineering Materials Research Institute of China National Petroleum Corporation, was officially released, filling the gap of my country's leading international standards for oil pipe products.
Industrial Ceramic Lined Tubes
Due to corrosion, wear, mechanical damage and other reasons, a huge amount of metal oil pipes is scrapped every year in my country, which brings huge economic losses, waste of energy resources and environmental hazards. Strengthening the anti-corrosion, wear-resistant and mechanical properties of metal oil pipes, and at the same time realizing the remanufacturing and reuse of waste oil pipes, can not only reduce the failure risk of oil pipes from the source, but also meet the needs of national remanufacturing development strategies such as "Made in China 2025". Produce great economic value and social benefits.
And wear resistance, high temperature resistance, acid and alkali corrosion resistance are the specialties of advanced ceramics. Advanced ceramic materials are widely used in industrial equipment and pipelines due to their excellent performance. In addition to oil and natural gas pipelines, they are also widely used in coal-fired power plant coal transportation pipelines, cement plant powder separation system pipelines and other fields. . By replacing ordinary metal materials, the service life of the pipeline and the continuous production capacity have been greatly improved. At present, the wear-resistant ceramic parts in the field of engineering ceramics at home and abroad are mostly made of alumina, zirconia, silicon carbide, silicon nitride and other materials, of which alumina ceramics are the most widely used.
It is understood that this international standard mainly stipulates the manufacturing process, material requirements, mechanical properties, inspection and testing and other technical requirements of ceramic-lined tubing for oil and gas industry, and is suitable for the manufacture and reuse of new (old) ceramic-lined tubing for oil production and water injection. manufacture. Ceramic lined tubing is a high-tech product that combines the ceramic layer on the inner wall of the tubing by using the "self-propagating high temperature synthesis method". It has the characteristics of wear resistance, heat resistance, corrosion resistance, and anti-scaling. More than 30 times, especially suitable for oil and water wells with severe corrosion, scaling and waxing.
The successful release of this standard shows that my country's technical capabilities in the field of petroleum pipes and the right to speak on international standards have been significantly improved, and it will also lay the foundation for effectively avoiding barriers to international trade, promoting the advancement of industry technology and the green and low-carbon development of the industry.
