CSA G40.21 grade 350WT plates API Std 650 petroleum storage tanks

The advantages of API 650 floating roof tanks have obvious environmental and economic benefits: in a specific climate environment, according to historical data, the economic value of the API Std 650 petroleum storage tanks floating roof tanks in API 650 due to the reduction of oil and gas volatilization within 3-6 months is equivalent The installation and purchase cost of the API Std 650 petroleum storage tanks inner floating roof means that the cost of the inner floating roof can be recovered within half a year.

As we know, the vertical metal tank, API Std 650 petroleum storage tanks is welded by many components, and the welding quality of each component determines the later use effect of the API Std 650 petroleum storage tanks. Professional API Std 650 petroleum storage tanks manufacturers should have a set of professional skills in the welding process of API Std 650 petroleum storage tanks. Key points for weld inspection of vertical metal tank, API Std 650 petroleum storage tanks:
1. It is strictly forbidden to paint the welds before passing the inspection.
2. Visual inspection shall be carried out for welds.
3. NDT shall be carried out on the weld.

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 Std 650 petroleum 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.

Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.

The company uses outsourced logistics operations. Our cooperated professional third-party logistics providers use the advantages of large-scale production and cost advantages to achieve cost savings by increasing the utilization of resources in each link, so that we can benefit from the separation of cost structure. Therefore, we can also provide customers with better, faster and more efficient cargo transportation, delivery, and lower freight costs.
