API Spec 5L pipe API 650 aboveground oil storage tanks
Test plates shall be welded using the same qualified welding procedure and electrodes that are required for the tank shell plate joints. The API 620 steel storage tank test plates need not be welded as an extension of the tank shell joint but shall be welded in the required qualifying positions. One test weld shall be made on a set of plates from each specification and grade of API 650 aboveground oil storage tanks plate material, using a thickness that would qualify for all thicknesses in the shell. Each test welded of thickness t shall qualify for plate thicknesses from 2t down to t/2, but not less than 5/8 in. For plate thicknesses less than 5/8 in., a test weld shall be made for the thinnest shell plate to be welded; this test weld will qualify plate thicknesses from t up to 2t.
The API 650 petroleum storage tank standard is one of the most widely used design specifications. It is the API 650 standard of the American Petroleum Institute. The main goal of the API 650 standard is to promote the purchase and construction of vertical, above-ground, and welded manufacturing API 650 aboveground oil storage tanks tanks through the requirements contained in its parts to ensure that the required safety regulations are met.
In October, 2018, our Malaysia customer purchased 600 Tons CCS-AH36 Ship Building Steel Plates to use in their shipbuilding project .This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, API 650 aboveground oil storage tanks shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of API 650 aboveground oil storage tanks CCS-AH36 Ship Building Steel Plates.
}The factors affecting the "small breathing" loss of API 650 aboveground oil storage tanks are: 1. It is related to the change of temperature difference between day and night. The greater the change of temperature difference between day and night, the greater the loss of "small breathing"; on the contrary, the smaller the change of temperature difference between day and night, the smaller the loss. 2. It is related to the sunshine time of the oil storage tank. The longer the sunshine, the more the "small breathing" loss; otherwise, the less the loss.
