API standard 650 unanchored liquid-storage tanks greater than 60 m in diameter

If additional requirements are met, higher internal pressures are allowed. API 650 only covers tanks that support the whole bottom evenly and API standard 650 unanchored liquid-storage tanks tanks in non-refrigerated service that have a maximum design temperature of 200 degrees F. It requires that you have a minimum material thickness of 3/16 inch.

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 API standard 650 unanchored liquid-storage tanks 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.

The preparatory work before the construction of the API standard 650 unanchored liquid-storage tanks is an important part of the oil tank project. Material purchase preparation before the construction of the API standard 650 unanchored liquid-storage tanks:
Before API standard 650 unanchored liquid-storage tanks construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.

Our vasion is to create a first-class steel plate manufacturing enterprise with international competitiveness. Business Vision: Improve value with quality and become the leader in the industry. Core values: people-oriented, integrity, responsibility, excellence. Development strategy: Seek development through science and technology, and seek benefits from management. Besides, we will create a harmonious business atmosphere, unblock the channels for employees to communicate, and build a stage for various sports and talents.

Booking space and making power of attorney (ten copies of order); the data of the original order shall be correct and consistent to the greatest extent when making the order, so as to reduce the frequent changes in the subsequent process. For booking with the company's seal for booking space, if the accessories for booking space (such as the price confirmation document of the shipping company) need to be provided, they can only be booked with all of them. Obtain the shipping space allocation receipt and extract the ship name, voyage number and B / L number information.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
