API Std 650 low-alloy steel tanks examination requirements

BEBON is a large steel group with finance department, production department, sales team, technical department, quality control department, logistics department and after-sales service team. We are committed to creating a various culture system with its own characteristics, and work hard to create a first-class steel plate company in China. Based on the business philosophy of quality-oriented and strengthened management, the company continues to develop in this industry.The Field-assembled storage tanks manufacturer shall determine that each magnetic-particle examiner meets the following requirements:a)The examiner has vision with correction, if necessary, to be able to read a Jaeger-Type No. 2 Standard Chart at a distance of not less than 12 in. and is capable of distinguishing and differentiating contrast between colors used. These requirements shall be checked annually.b)The examiner is competent in the techniques of the magnetic-particle examination method for which the API Std 650 low-alloy steel tanks examiner is certified, including making the examinations and interpreting and evaluating the results; however, where the examination method consists of more than one operation, the examiner may be certified as being qualified only for one or more of these operations.While GB50341 generally takes the weld coefficient as 0.9;When the minimum yield strength of API Std 650 low-alloy steel tanks steel plate is greater than 390 MPa, take 0.85. The thickness of API 650 tanks is generally smaller than that of GB50341, and this difference is particularly evident in the design of large tanks, where the overall weight of the tanks varies greatly.Advanced typical figures and typical deeds are the embodiment and symbol of API Std 650 low-alloy steel tanks enterprise spirit, outstanding ideas and vivid images, with strong demonstration, radiation and transmission effect. Without distinctive typical characters, there is no unique enterprise culture. In carrying out the construction of enterprise culture, the advanced enterprise culture should be typified. Vigorously excavate, discover, cultivate and summarize the company's API Std 650 low-alloy steel tanks advanced models.The water dissolved in the oil will be separated out from the oil stored in the API Std 650 low-alloy steel tanks for a long time, and the acidic water layer will appear at the bottom of the API Std 650 low-alloy steel tanks for a long time, which will accelerate the corrosion of the API Std 650 low-alloy steel tanks and cause the wall thinning and even leakage. With the increase of service life, the API Std 650 low-alloy steel tanks must be inspected and cleaned regularly to check the hidden danger.
