1. Introduction to SPV490 steel plate.
SPV490 belongs to the steel plate used in boilers and pressure vessels, and the implementation standard of SPV490 is; GB19189-2003 special technical conditions.
2. Introduction to the performance indicators and uses of SPV490 steel plate.
SPV490 is a steel plate for large-scale storage tanks made in Japan, and the SPV490 container plate corresponds to the domestic 12mnnivr. Steel plates for storage tanks are widely used in key projects such as tank construction at home and abroad, and have become a first-class manufacturer of steel plates for storage tanks in China, with the best performance in the industry. The steel used for the storage tank of Nanjing Iron and Steel is widely used in national strategic reserves such as Sinopec, PetroChina, CNOOC, Sinochem, etc., local commercial reserves, and "National Belt and Road" projects. In 2008, Nanjing Iron and Steel began to supply 12mnnivr (equivalent to SPV490) of large-scale ** storage tank plates, and by 2019, Nanjing Iron and Steel has supplied more than 533 units, with a total of 400,000 tons. At present, the domestic market share of Nanjing Iron and Steel large-scale storage tank plate ranks first (52%). It is mainly used to manufacture storage tanks of more than 50 cubic meters, and can also be used to manufacture single-layer coil welding containers, multi-layer heat sleeve coil welding containers, multi-layer wrapping containers, etc.
Class II and III containers and cryogenic pressure vessels. It is widely used in petroleum, chemical industry, power station, boiler and other industries, and is used to make reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, boiler steam drums, liquefied petroleum equipment, high-pressure water pipes of hydropower stations, hydraulic turbine volutes and other equipment and components.
Third, the delivery status of SPV490 steel plate.
SPV490 steel plate is delivered in the default normalized state, and can be delivered according to customer requirements such as tempering, normalizing and tempering, quenching and tempering, etc. according to different needs.
SPV490 steel plate thickness flaw detection can be done; 1 probe, 2 probe, 3 probe.
SPV490 steel plate thickness extension can be done; z15、z25、z35
4. SPV490 steel plate is a kind of steel plate for boilers and pressure vessels, and its implementation standard is GB19189-2003 special technical conditions. This steel plate is made in Japan and is especially suitable for the construction of large-scale storage tanks. In China, Nanjing Iron and Steel is one of the main manufacturers, and its SPV490 steel plate has been widely used in many key projects at home and abroad.
SPV490 steel plate has excellent performance indicators and a wide range of uses. It can be used not only to manufacture large storage tanks, but also to manufacture various types of pressure vessels such as single-layer and multi-layer coil-welded containers, spherical tanks, oil and gas tanks, liquefied gas tanks, etc. These containers are widely used in petroleum, chemical, power station, boiler and other industries, and are indispensable and important equipment in modern industry.
In the manufacturing process, SPV490 steel plate needs to be normalized, and it is delivered in different states such as tempering, normalizing plus tempering or quenching and tempering according to customer needs. In addition, there are strict requirements for the thickness detection and elongation of steel plates to meet the needs of different customers.
In short, as a high-performance steel plate for boilers and pressure vessels, SPV490 steel plate has excellent performance indicators and a wide range of uses that make it highly competitive in the domestic and foreign markets. In the future, with the continuous development of the national energy and chemical industry, the demand for SPV490 steel plate will continue to grow, and its application prospects will be broader.
