API 650 uplifting tanks calculated failure pressure

Ultrasonic testing can find the internal defects of API 650 uplifting tanks welding joint, this detection method is very accurate for the internal layer defects of oil tank, but ultrasonic detection is not suitable for the detection of thin-walled storage tank materials. Dye penetrant testing is only suitable for detecting the defects of the surface opening of API 650 uplifting tanks and so on metal oil tanks. The feature of this method is convenient and fast.Charpy 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.There is a gap of 100 mm to 500 mm between the shell of API 650 crude oil storage API 650 uplifting tanks tank and the floating plate of external floating roof to ensure that there is no chuck during operation. Use API 650 uplifting tanks edge sealing system to reduce edge evaporation. The support legs of API 650 crude oil tank floating roof are usually movable and retractable and suspended in liquid.Integrity based:To customers, we should value our credit and keep our good image forever.To colleagues: respect each other, trust each other, make efforts togetherService first:Customer satisfaction is always the first pursuit.The company provides customers with not only advanced technology and high-quality API 650 uplifting tanks products, but also the spirit of credit and service.Innovation:We are good at learning, drawing on the strengths of all, innovating and developing, introducing, researching and developing the latest technology, and making our products have a stronger vitality.The high strength API 650 uplifting tanks low alloy steel, which is shorten as HSLA steel, is one of our main products.
