A841 Gr B Cl 2 plates API standard 650 ground supported flat-bottom tanks

The main reason of "small breathing" loss of API standard 650 ground supported flat-bottom tanks is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API standard 650 ground supported flat-bottom tanks also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API standard 650 ground supported flat-bottom tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.

The API Std 650 standard published by the American Petroleum Institute (API) is designed to provide the petroleum industry with welded steel tanks for use in the API standard 650 ground supported flat-bottom tanks storage of petroleum products and other liquid products commonly handled and stored by the various branches of the petroleum industry.

When talking about our team, it is hard not to mention our QC department (Quality Control). We have built strict qualitycontrol system to guarantee the steel quality. During the steel materials production, we have strict monitoring measures and indicators, and ensure no chemical composition, mechnical properties and so on technical problems for the steel materials API standard 650 ground supported flat-bottom tanks. After production, our QC department will conduct another inspection regarding to the steel quantity, dimension, mark and so on points before delivery.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
