ISO 630 Gr E275C plates API Std 650 welded storage tanks
Density of API Std 650 welded storage tanks Liquid StoredThe density of the liquid stored shall be its maximum density within the range of design temperatures, but no less than 29.3 lbf/ft3 for methane, 34.21 lbf/ft3 for ethane, and 35.5 lbf/ft3 for ethylene.Design Metal TemperatureThe design metal temperature of each component exposed to the liquid or vapor being stored shall be the lower of the temperatures specified as follows: The design metal temperature of the components of the API 620 single-wall tank or the inner tank of a double-wall tank shall be the minimum temperature to which the tank contents shall be refrigerated, including the effect of subcolony at reduced pressure.
This specification, in conjunction with API 650 Standard, prescribes minimum standards for the API Std 650 welded storage tanks design, supply, fabrication, erection, and testing of field erected welded steel storage tanks complete with accessories as specified herein and as shown on attached Datasheets and/or Drawings.
A Uganda client purchased 2100 tons SG255 gas cylinder steel coils in 2018. It is the first company in Uganda to provide re-furbishing, re-certification and manufacturing of new lpg cylinders. They have regular demands for sg255 coils API Std 650 welded storage tanks every 3 months. Limited by inland location, we can only ship container to mombasa, and then transfer to kampala. OurJISG3116 SG255 steel product is grade for gas cylinder steel with the tensile strength of 400MPa and the yield strength of 255MPa.
}The process parameters should be strictly controlled in sand blasting of API Std 650 welded storage tanks. The working pressure of abrasive chamber is between 0.5 and 0.6a, and the outlet pressure of air compressor shall not be lower than 0.6 WPa. According to the test results, the distance between nozzle and workpiece shall be controlled at 80 - 200 mm and spraying angle of 30 ~ 75°is appropriate.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
