5652 aluminum plate API standard 650 low-alloy steel tanks

The refrigerated tank primary components shall also include those parts of a single-wall or an inner tank that are not in contact with the refrigerated liquid but are subject to the refrigerated temperature. Such API standard 650 low-alloy steel tanks components include roof plates, roof manways and nozzles with their reinforcements, roof-supporting structural members, and shell stiffeners when the combined tensile and primary bending stresses in these components under design conditions are greater than 6000 lbf/in.2.

API 650 stipulates that an open tank should be provided with a wind-resistant ring to ensure that the API standard 650 low-alloy steel tanks tank body maintains its roundness when subjected to wind. There are no hard and fast rules for vault API 650 storage tanks. It can be determined by comparing the equivalent wall height with the maximum height of the unreinforced tank wall.

In October 19th 2018, our Malaysia customer purchased 600 Tons CCS Grade AH36 mairne steel API standard 650 low-alloy steel tanks plates to use in their shipbuilding project .This customer is a famous shipyard company in Malaysia. Their company has the business scope of tourism, shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality for CCS Grade AH36 mairne steel plates. After visiting our steel milll, the customer is very satisfied with the quality of this batch of CCS Grade AH36 steel plates.

Unqualified welding quality of API standard 650 low-alloy steel tanks is prone to hidden dangers such as oil tank steel plate cracks and leakage. To avoid this situation as much as possible, it needs to be avoided when the oil storage tank is manufactured. Scientific and reasonable measures are adopted to control the welding quality when welding the API standard 650 low-alloy steel tanks. How to reasonably control the welding process quality of oil storage tanks?

Both parties shall confirm the API standard 650 low-alloy steel tanks material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API standard 650 low-alloy steel tanks steel plant.
