API standard 650 ambient temperature tanks corrosion allowance

API standard 650 ambient temperature 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.

Upon completion of construction, provide Purchaser with copies of Field Erected API standard 650 ambient temperature tanks storage tank Datasheets in accordance with Appendix L of API 650, which reflects the as-built conditions, certifying that the tank conforms with the requirements of this specification.

In December, 2018, our Vietnam customer purchased 352 tons SA387Gr12Cl2 and SA387Gr11Cl2 API standard 650 ambient temperature tanks steel plates for their tank fabrication project. The customer need those cargo urgently, and we keep many stock in warehouse , it only takes about 3days we collect total cargo for shipping to customer. The customer are very appreciate our quality and service. They API standard 650 ambient temperature tanks become our regular customer and repeat order to us every month.

Ultrasonic testing can find the internal defects of API standard 650 ambient temperature tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API standard 650 ambient temperature tanks and so on metal oil tanks. The feature of this method is convenient and fast.

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.
