EN S355J2 plates API standard 650 welded steel storage tanks

Large Steel storage tank Anchorage
In addition to the loads in API 620 oil storage tank Q.4, Q.5.1, and Q.5.2, the anchorage for the tank that contains liquid, whether it be a single-wall tank or the inner tank of a double-wall tank, shall be designed to meet the requirements of Q.3.6.2 through Q.3.6.5. The anchorage shall accommodate movement of the tank wall and bottom caused by thermal changes. For anchored flat-bottom tanks, the anchorage shall be designed as described in Q.3.6.4.1 through Q.3.6.4.3.

In Appendix E to API 650 oil storage tank, the maximum values of inertia force, pulse pressure and convection pressure are superimposed, and tend to be conservative.In GB50341, only pulse pressure is calculated for API standard 650 welded steel storage tanks tanks below 5000 m.

In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe API standard 650 welded steel storage tanks for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.

During the use of API standard 650 welded steel storage tanks, the tank material is prone to crack and leakage under the action of pressure, corrosion, wear and other conditions. Especially in the oil producing area, the temperature difference in four seasons is large and the natural environment is bad, which will accelerate the consumption of oil storage tank and cause many potential safety hazards. Therefore, the API standard 650 welded steel storage tanks must undergo strict inspections before being put into use after the production and installation are completed, so as to avoid cracks and leakage in short-term use and affect production safety.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
