API standard 650 cylindrical liquid-storage tank overturning moment

This standard only applies to API 650 storage tanks API standard 650 cylindrical liquid-storage tank 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).

Unqualified welding quality of API standard 650 cylindrical liquid-storage tank is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API standard 650 cylindrical liquid-storage tank. How to reasonably control the welding process quality of oil storage tanks?

In cylindrical tank walls, the longitudinal weld joints in adjacent shell courses, including compression ring welds, shall be offset from each other a minimum distance of 12 in. The butt-weld around the periphery of a thickened insert plate, or the fillet weld around the periphery of a reinforcing plate, shall be at least the greater of 10 times the shell thickness or 12 in. from any butt-welded seam or the bottom-to-shell or roof-to-shell joint. As an alternative, the insert plate (or the API standard 650 cylindrical liquid-storage tank reinforcing plate in an assembly that does not require stress relief) may extend to and intersect a flat-bottom-to-shell corner joint at approximately 90 degrees.

Our quality control department will do inspection for details of the steel materials API standard 650 cylindrical liquid-storage tank before delivery. We would invite the customer side to attend the inspection together. If they can not come, we will also take rich pictures for them to check. Meanwhile, we will publish inspection report and send them the PDF version. Besides, we accept any third party inspection such as SGS, BV, etc. And our quality control department will support the third party to inspect the steel materials smoothly and try our best to deliver the qualified steel materials to customers earlier.

In addition to our own truck fleet, we also have long-term cooperation with certain logistics companies to ensure that we can deliver API standard 650 cylindrical liquid-storage tank goods in time and smoothly. At the same time, because of the long-term cooperation and huge shipping volume, we can get a good transportation price and save transportation cost for the company and customers. Meanwhile, we have Shipping Department to arrange shipping work in advance. So as not to waste time on transportation both in land and on the sea.
