Api 620 vs api 650

Re: API 620 verses 650 standard? They apply to different tanks, so it would be hard to say whether one is more restrictive than the other. API 650 applies to vertical cylindrical tanks, API 620 to tanks formed by a surface of revolution, (mostly of double curvature).

API 650 applies to vertical cylindrical tanks, API 620 to tanks formed by a surface of revolution, (mostly of double curvature). Note that Appendix M of API-650 goes up to 500 degrees, whereas API-620 is limited to 250. API-620 may be applied to horizontal tanks, but doesn't actually include any design provisions for them. Generally, horizontal tanks would be built to ASME code if pressurized or UL standards if not. These are intended for oil-field use, put out the by the API "production" people. API-650 can be used for any capacity or dimensions.
