EN 10025 grade S355 plates API 650 self-anchored tanks

The Charpy V-notch test shall be used, and the minimum impact value at the design metal temperature shall be as given in Table R-2. For subsize specimen acceptance criteria, see ASTM A20. An impact test temperature lower than the design metal temperature may be used by the API 620 welded storage tanks Manufacturer, but in such a case the impact values at the test temperature must comply with Table R-2.

This standard only applies to API 650 storage tanks API 650 self-anchored tanks with uniform bottom support and non-refrigerated service storage tanks with a maximum design temperature of not more than 93 degrees Celsius (200 degrees Fahrenheit).

The finned tube heating device for high temperature heat transfer oil for large API 650 self-anchored tanks has the advantages of convenient inspection and maintenance. The high-efficiency fin heating coil assembly is composed of spirally arranged finned coils. The fins are mainly arranged in the straight pipe section, and the whole assembly is supported by several angle steel supports. The high-efficiency fin heating coil component can enter and exit from the manhole of the API 650 self-anchored tanks, which is convenient for maintenance and repair.
