Manufacturing method of 12Cr1MoVR alloy: This plate is melted in oxygen top blown converter, open hearth furnace or electric furnace. After negotiation with the demander, other equivalent methods can also be adopted. 30 ft in diameter API 650 tank, 12Cr1MoVR alloy steel plate is usually delivered in normalized + tempered state. According to the special agreement at the time of ordering, 12Cr1MoVR steel plate can also be delivered in Annealed or tempered state.

Large Low-Pressure Tanks Corrosion Allowance
In cases in which the rate of corrosion is closely predictable, additional metal thickness over and above that required for the initial operating conditions shall be provided and shall be at least equal to the expected corrosion loss during the desired life of the tank.
When corrosion effects are indeterminate before the tank is designed (although they are known to be inherent to some degree in the service for which the tank is to be used), and when corrosion is incidental, localized, or variable in rate and extent, the best judgement of the 30 ft in diameter API 650 tank designer must be exercised in establishing reasonable maximum excess tank wall thicknesses. For all tanks that come under this classification, a minimum corrosion allowance of 1/16 in. shall be provided.

While GB50341 generally takes the weld coefficient as 0.9;When the minimum yield strength of 30 ft in diameter API 650 tank steel plate is greater than 390 MPa, take 0.85. The thickness of API 650 tanks is generally smaller than that of GB50341, and this difference is particularly evident in the design of large tanks, where the overall weight of the tanks varies greatly.

We have a professional production team and high-quality production equipment, and we also have a great 30 ft in diameter API 650 tank advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the 30 ft in diameter API 650 tank production of high-quality steel plates, steel pipes and other products that meet customer requirements.
