The foundations for API Std 650 stainless steel storage tanks

After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with usCharpy V-notch specimens shall be taken from the weld metal and from the heat-affected zone of the welding procedure qualification test plates or from duplicate test plates.
Weld metal impact specimens shall be taken across the weld with the notch in the API 620 oil tank material weld metal. The specimen shall be oriented so that the notch is normal to the surface of the material. One face of the specimen shall be substantially parallel to and within 1/16 in. of the surface.The API Std 650 stainless steel storage tanks most widely used and most commonly used standard for global storage tank construction and procurement is API 650. The Chinese translation name is "AP1650 Steel Welded Petroleum Storage Tank". API 650 storage tank is for commonly used oil, gasoline, diesel, chemical and production water storage, etc.Aspire to technological innovation and pursue first-class quality steel API Std 650 stainless steel storage tanks products.Take independent innovation as an important support for the sustainable development of iron and steel industry, strengthen the main position of technological innovation, accelerate the original innovation, integrated innovation, introduction, digestion, absorption and re innovation, improve the technological innovation system, and cultivate the core technology and brand products of independent intellectual property rights.Generally speaking, the duration of the "exhalation" of the API Std 650 stainless steel storage tanks is longer than that of the "inhalation" of the API Std 650 stainless steel storage 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 Std 650 stainless steel storage tanks location, open area of the API Std 650 stainless steel storage tanks, atmospheric pressure, filling degree of API Std 650 stainless steel storage tanks, etc. When the API Std 650 stainless steel storage 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.
