API 650 low-alloy steel tanks bolting

Testing the Outer Tank: While the test pressure is being held, all welded seams and connections in the outer shell and roof shall be thoroughly inspected with a solution film unless they were previously checked with a vacuum box. The API 650 low-alloy steel tanks air pressure shall be released. Pressure relief and vacuum relief valves shall be checked by applying the design gas pressure to the outer tank, followed by evacuation of the outer space to the vacuum setting of the relief valve.

For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API 650 low-alloy steel tanks Elevation or radial location - plus or minus 6 mm. API 650 tanks Flange tilt in any plane, measured on the diameter across the gasket surface - plus or minus degree but not exceeding 5 mm. Flange bolt hole orientation - plus or minus 2 mm.

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 low-alloy steel 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 low-alloy steel tanks CCS-AH36 Ship Building Steel Plates.

Generally speaking, the duration of the "exhalation" of the API 650 low-alloy steel tanks is longer than that of the "inhalation" of the API 650 low-alloy steel tanks every day. There are many factors affecting the "small breathing" loss, mainly including the following points: the change of temperature difference between day and night, sunshine time of the API 650 low-alloy steel tanks location, open area of the API 650 low-alloy steel tanks, atmospheric pressure, filling degree of API 650 low-alloy steel tanks, etc. When the API 650 low-alloy steel tanks is full of gas, the space volume is small, and the "small breathing" loss is less; if the space volume is large, the loss is also large.
