High strength hot rolled steel strip for pressure vessel (GB/T5139-1993)
Pressure vessels are closed containers for storing liquids and gases at high pressure, and their structural and performance requirements are very demanding. The high-strength hot-rolled steel strip for pressure vessels produced in accordance with GB/T 5139-1993 has successfully passed various tests and inspections, and is widely used in various pressure vessels.
High strength hot rolled steel strip for pressure vessels is made of high quality low carbon steel low alloy thin strip, adopting advanced technologies including controlled rolling, controlled cooling and controlled tempering, and using reasonable ratio of alloy elements to further enhance the strength, hardness and wear resistance. It meets the construction quality requirements of pressure vessels and is favored by users.
The high-strength hot-rolled steel strip for pressure vessel (GB/T 5139-1993) produced by our company mainly includes Q245R, 15CrMog, 12Cr2Mog and other steel strips. 15CrMog Steel Strip is the common material used in producing ordinary and middle-pressure vessels and can be used under the temperature ranging from -20 to 100 ℃. 12Cr2Mog steel strip has production heat strength, creep strength and oxidation resistance which is great. It is mainly used to produce middle temperature pressure vessels, and can be used under the temperature ranging from -27 to 440 ℃. Q245R steel strip mainly provides a higher temperature resistance and is mainly used to produce low-temperature pressure vessels, and can be used under the temperature ranging from — 45 to 500 ℃.
To guarantee the performance of the high-strength hot-rolled steel strips for pressure vessels produced in accordance to GB/T 5139-1993, our company strictly complies with the quality management system ISO9000 and implements a set of series of chemical analysis tests and mechanical property tests, such as carbon equivalent, rare earth elements content, tension test and flattening test, etc. With its good ductility, toughness and excellent weldability, our high-strength hot rolled steel strips for pressure vessels are able to bear higher temperature and high pressure.
It is believed that the excellent performance and reliable quality of the hot-rolled steel strips for pressure vessels we provide, which is produced in accordance with GB/T 5139-1993, can meet the needs of customers in terms of different grades, sizes and specifications. We believe that our hot-rolled steel strips will bring you a satisfactory experience in terms of both cost and quality.
