For shell nozzles, the common practice is to use the same thickness and grade as API Std 650 larger diameter tanks tank-bottom reinforcing plate1JStephen, Do you mean 5.7a and 5.6b? Because in 5.6a and 5.6b, I can not see, it states about nozzle reinforcement plate thickness. "If a shell API Std 650 larger diameter tanks tank-bottom reinforcing plateAll holes in the shell for nozzles larger than 2" NPS need reinforcement. Reinforcement calculations are essentially area replacement in the verti API Std 650 larger diameter tanks tank-bottom reinforcing plateIFRs, But I can not find the formula to calculate the thickness of reinforcement pad in API 650, do you have any reference for that? Well, I ha API Std 650 larger diameter tanks tank-bottom reinforcing plateWhen you have calculated the area required to reinforce the opening, it will be in square inches ( or square MM ). Divide this by the sum of the r API Std 650 larger diameter tanks tank-bottom reinforcing plateIFRs, I don't get "the reinforcement height above and below the centerline of the opening to the height of the opening" what is the difference be API Std 650 larger diameter tanks tank-bottom reinforcing plate"what is the difference between height above the centerline of the opening and height of the opening?

API Std 650 flat-bottom oil storage tanks , floating roof tank is composed of vertical cylindrical tank wall and floating roof, which is floating on the surface of liquid storage. The volume of floating roof storage tank is generally large , and its bottom plate is arched edge plate . [DOC]APPENDIX BRECOMMENDATIONS FOR DESIGN For hydrostatic testing requirements refer to API 650 7.3.6. Slope 1 1.5. Notes Tank shoulder 1 m (3 ft) wide for tanks under 15 m (50 ft) diameter and 1.5 m (5 ft) wide for tanks over 15 m (50 ft) diameter. Tank with a cone up bottom, recommended foundation height at tank shell is 450 mm (18 in) above the surrounding ground elevation. When to use an API 650 shell plate?When to use an API 650 shell plate?API 650 is for new tanks. It is common to order an extra bottom course shell plate to cut repads from, which makes all the calculations and justifications moot.API 650 Thickness Reinforcement Plate for Nozzles API Std 650 larger diameter tanks tank-bottom reinforcing plate

What are the API requirements for storage tanks?What are the API requirements for storage tanks?In fact, Section 7 of API-653 has specific requirements laid down for any repair or alteration to be carried out in storage tanks. Following are the main guidelines Removal and subsequent removal of the shell plate material Repair of any defect in the shell plate materialAPI Recommended Steps To Follow For Storage Tank Repair - GSC Tanks Technical Inquiries for API Standard 650, Welded Tanks

Is it permissible to use Group I plates for a tank bottom , except for plates welded to the shell, for tanks with a -50°F design metal temperature? API 650 only addresses toughness of bottom plates welded to the shell, per Section 2.2.9 or 2.2.10. 2.2.9 Table 2-3 9th - May 1993 Does Table 2-3 only relate to plates that are to be heat-treated API Std 650 larger diameter tanks tank-bottom reinforcing plate Reinforcement Pads - API 650 & AWWA D 100For API roof nozzles, see the footnote on Table 3-14. Presumably, nozzles over 6" always require a repad. For roof manways, they appear to be optional. The problem with API -650 is that they give design rules AND tables, and the two don't agree. That is, the tables meet the rule requirements, but also exceed the rule requirements.

Can a tank bottom be repaired under API 653?Can a tank bottom be repaired under API 653?Yet, API 653 does not prohibit repair of the shell-to-bottom weld. Weld repairs in the bottom critical zone should be treated no differently than those permitted during construction of new tanks.Repair of Tank Bottoms in Atmospheric Storage Tanks API 650 petroleum storage tanks bottom-transition plate API Std 650 larger diameter tanks tank-bottom reinforcing plate

The soil endurance in the API 650 petroleum storage tanks construction area plays a decisive role in the basic cost of the tank . In areas with high soil resistance, not only the cost of foundation treatment can be greatly reduced, but also the ratio of height to diameter of storage tank can be obtained. Therefore, the investment cost of the API 650 petroleum storage tanks can be greatly saved in the area with large API 650 Thickness Reinforcement Plate for Nozzles API Std 650 larger diameter tanks tank-bottom reinforcing plateReinforcement (replacement area) can be found in a repad, excess shell plate thickness, thickened shell plates, the nozzle neck, etc as listed in API 650 5.7.2.3 through 5.7.2.7. In some situations the repad thickness may be reduced to zero and sometimes it is useful to do so.
