Is there a difference between seamless steel pipe and ordinary steel pipe? The general requirements of NV F32 hull steel heavy plate ordinary steel pipe are not so high, which are used in ordinary buildings or structures. According to the different materials and standards, seamless steel pipe will have different application environment. For example, seamless steel pipe for boiler requires pressure value. Seamless steel pipe for petroleum cracking also has its own corresponding national standard. Seamless steel pipe can be divided into fluid pipe, gas cylinder pipe, boiler pipe, oil pipe, automobile steel pipe, ship pipe, structural pipe, etc.
Both 14Cr1MoR pressure vessel steel and 15CrMoR pressure vessel steel belong to Cr-Mo hydrogen resistant steel, and they are special steel in strict sense. NV F32 hull steel heavy plate, Cr-Mo hydrogen resistant steel is suitable for petrochemical, nuclear power, steam turbine cylinder block, thermal power and other large-scale equipment with high temperature and high pressure and connected with hydrogen or hydrogen mixed medium. Moreover, 15CrMoR pressure vessel steel has high endurance strength below 550 °C.
The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for NV F32 hull steel heavy plate pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common NV F32 hull steel heavy plate carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
The automobile steel coil and sheets are one of our main steel materials exported to the overseas. For any questions about automobile steel, for example, JIS G3113 SAPH440 NV F32 hull steel heavy plate chemical & mechanical composition, S355MC material specification, S700MC material properties, QSTE 380 TM equivalent, please contact us freely. Our sales person and technician will give you professional answers. And welcome to consult us about automobile steel price.
Both parties shall confirm the NV F32 hull steel heavy plate material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the NV F32 hull steel heavy plate steel plant.
