Application of 09MnNiDR:

With the rapid development of domestic economic construction, the demand for low-temperature storage tanks such as liquefied petroleum gas tanks is increasing in many industries. 09MnNiDR, as a special steel for domestic LPG cryogenic storage tanks, has become the preferred domestic material for manufacturing large LPG cryogenic storage tanks due to its high strength, good weldability and good low temperature toughness.

At present, 09MnNiDR steel plate has been widely used in low-temperature pressure vessels ranging from - 40 C to - 70 C. 09MnNiDR is a special steel for domestic LPG cryogenic storage tanks. The maximum thickness of 09MnNiDR steel plate is 200 mm. 09MnNiDR has gradually replaced imported cryogenic container steel plates in the fields of deethane tower, CO2 absorption tower, medium pressure flash tower, cooler, deethane tower, re-absorption tower, compressor casing and low temperature storage tank manufacturing of propane in petroleum and chemical equipment. Petrochemical equipment, power plants, boilers and other industries, used to make reactor, heat exchanger, separator, spherical tank, oil and gas tank, liquefied gas tank, nuclear reactor pressure shell, boiler drum, liquefied petroleum cylinder, high-pressure water pipe of hydropower station, turbine volute and other equipment and components.
