API Std 650 aboveground welded storage tanks roof loads

storage tanks API Std 650 aboveground welded storage tanks built to these standards are spread across U.S. refineries, terminals, pipelines, and production facilities. The API 650 petroleum storage tank detailed standard specifies the design, processing, welding, inspection and installation procedures of the storage tank.

The engineering quality of API Std 650 aboveground welded storage tanks not only affects production and operation, but also affects the life safety of the staff. The factors affecting the API Std 650 aboveground welded storage tanks construction quality are all aspects, any link, any part of the problem will affect the whole project, so the quality management is paid more and more attention. How to ensure the engineering construction quality of oil tank? First, make API Std 650 aboveground welded storage tanks construction technical preparation carefully, understand the design intent, master the construction acceptance specification, and make detailed construction technical disclosure to the construction team.

The API Std 650 aboveground welded storage tanks stiffener ring and backing strip (if used) are primary components, and they shall comply with the requirements of API 620 storage steel tank Q.2.1. The stiffener rings may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange.
Except for aluminum or stainless steel tanks, all fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole (see Figure Q-1), and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to the detail that includes stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API Std 650 aboveground welded storage tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.
