API Std 650 carbon steel tank drawings

BBN excels in the design, fabrication and erection of API-650 tanks. API (American Petroleum Institute) has created a set of standards for above ground API Std 650 carbon steel tank oil storage, but these tanks are also commonly used for gasoline, chemical and water storage. API-650 storage tank solutions range in size from an 8’ -0” diameter shop fabricated tank up to and beyond 100’ -0” diameter field erected storage tank applications.

In order to prevent the deformation of the bottom of metal vertical storage tank, API Std 650 carbon steel tank during welding, the number of welders should be reasonably distributed. When welding metal vertical API Std 650 carbon steel tank, personnel and welding position shall be reasonably allocated according to the actual situation of welding personnel, and random welding is not allowed.

Ultrasonic Examination of Butt-welds in Plates
Butt-welds in all tank wall courses subjected to a maximum actual operating membrane tensile stress, perpendicular to the welded joint, greater than 0.1 times the specified minimum tensile strength of the API Std 650 carbon steel tank plate material shall be completely examined.
Butt-welds in API 620 oil tank wall courses subjected to maximum actual operating membrane tensile stress, perpendicular to the welded joint, less than or equal to 0.1 times the specified minimum tensile strength of plate material shall be spot examined in accordance with Figure Q-2.

Our quality control department will do inspection for details of the steel materials API Std 650 carbon steel 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.

The company's logistics uses third-party logistics. This logistics model plays an important role in improving the efficiency of our business operations. Third-party logistics is an important form of logistics specialization. As a company specializing in logistics, third-party logistics companies have a wealth of experts who specialize in logistics operations, which is conducive to ensuring the professional production of the company, reducing costs, and improving logistics level of the company. Both the customers and the company benefit from the logystics mode.
