Anchorage design for API Std 650 flat-bottom steel tanks

The API 650 is widely used for tanks designed to withstand low internal pressures, for the API Std 650 flat-bottom steel tanks storage of typical products such as crude oil, petrol, chemicals and water. We have extensive experience when it comes to API 650 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3.

For the welding of API Std 650 flat-bottom steel tanks bottom, attention should be paid to the slag removal and drying of the welding joint before welding, and there is no sediment and oil contamination in the lap joint of steel plate. The manufacturing quality and production efficiency of the central plate can be obviously improved by adopting the rolling central plate. The butt joint is used between the rolling plates to improve the installation conditions of the central plate at the bottom of the API Std 650 flat-bottom steel tanks. The welding sequence of the central plate is from the center of the central plate to the surrounding.

API Std 650 flat-bottom steel tanks basic components are those that contain the vaporized liquefied gas from the stored refrigerated liquid but primarily operate at atmospheric temperatures because of insulation system design and natural ambient heating. These components shall comply with the basic rules of this standard. Examples of such components are the outer wall and roofs of double-wall tanks and roof components above an internally insulated suspended deck. The API 620 tank materials requirements are based on the storage of refrigerated products at the design metal temperature.

Our quality control department will do inspection for details of the steel materials API Std 650 flat-bottom steel tanks 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 Std 650 flat-bottom steel tanks 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.
