ISO 630 grade E275 plates API standard 650 special tank

The vent pipe mouth should be 4m or more above the ground. The nominal diameter of the API standard 650 special tank API 650 petroleum storage tank vent pipe should be no less than 50mm and a flame arrestor should be installed.

Due to irregular operation of API standard 650 special tank welding, there are many weld deformations during the construction process. Before specific operations, most construction units have formulated relatively complete construction plans and set up special welding process instructions, but the operators have not fully performed welding in accordance with various process guidance requirements and construction specifications, resulting in some quality problems of oil storage tanks. How can we reduce or even avoid this kind of situation?

The API 650 oil tank stiffener ring and backing strip, if used, are primary components, and they shall comply with the requirements of R.2.1. The API standard 650 special tank stiffener ring may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange. One rat hole with a minimum radius of 3/4 in. shall be provided at each longitudinal shell joint and ring juncture weld.
