API 650 aboveground steel oil storage tanks repairs to welds
The materials used in the construction of Appendix Q oil tanks may be subject to severe pitting, cracking, or rusting if they are exposed to contaminated test water for extended periods of time. The Purchaser shall specify a minimum quality of test water that conforms to Q.8.3.2 through Q.8.3.8. After the water test is completed, the tank API 650 aboveground steel oil storage tanks shall be promptly drained, cleaned, and dried.
API 650 internal floating roof tanks are generally called internal floating roof tanks, floating roof tanks, internal floating disk storage tanks, internal floating disk tanks, etc., specifically referring to API 650 storage tanks and oil tanks with aluminum, stainless steel, etc. The API 650 aboveground steel oil storage tanks inner floating roof of series material is an environmentally friendly and economical storage tank that prevents liquid from volatilizing.
In 2016. Our company offer 1200 tons API 5L GR.B hot rolled coil to Bangladesh——100 tons for 3.9*625mm, and 1100 tons for 7*683mm. It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016. They required the tolerance of thickness is +0.1/-0.2mm, and width tolerance is +/-0.5mm, which is a very high requirement for coil tolerance, but our mill handling this very well. and our Q/C department witness all of the process.
}Under the condition of static storage without receiving and sending operation, the temperature of gas space, evaporation rate, depth and pressure of vapor in the API 650 aboveground steel oil storage tanks will change with the change of temperature and pressure in a day. The oil loss caused by the process of discharging oil vapor and inhaling air gas is called "small breathing" loss, which is also called static storage loss of oil tanks.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
