6061 aluminum shapes API Std 650 carbon and low-alloy steel tanks
For API 650 tanks Projection from outside of tank shell to extreme face of flange - plus or minus 5 mm. API Std 650 carbon and low-alloy steel tanks Elevation or radial location - plus or minus 6 mm. API 650 tanks Flange tilt in any plane, measured on the diameter across the gasket surface - plus or minus degree but not exceeding 5 mm. Flange bolt hole orientation - plus or minus 2 mm.
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 carbon and 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.
Inspection of API Std 650 carbon and low-alloy steel tanks bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API Std 650 carbon and low-alloy steel tanks bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API Std 650 carbon and low-alloy steel tanks, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API Std 650 carbon and low-alloy steel tanks bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.
The company uses online training system to let all employees use fragmented time to carry out targeted training anytime, anywhere, regardless of time and geographical restrictions. Through training to improve API Std 650 carbon and low-alloy steel tanks work skills, at the same time, through training, let all improve their own quality education level, let employees work around a goal, create a career and achieve results.
The company adheres to the needs of customers, adheres to win-win integrity, and relies on scientific and technological innovation to continue to improve the level of logistics equipment technology and information technology, and enhance the logistics technology research and development and innovation capabilities. Based on market demand and innovation as the driving force for development, the company actively expands the field of logistics services, accelerates the extension of the logistics industry chain, and scientifically advances the diversification of the logistics industry.
The 365 day service system is implemented, and the business, loading and delivery are handled as usual in holidays and festivals. Actively help users solve difficulties. When users encounter difficulties in handling business, they should actively coordinate with the external solution; if they need to solve the problems internally, they should solve them in a timely manner without prevarication and wrangling. In line with the API Std 650 carbon and low-alloy steel tanks principle of "fairness, justice and timeliness", coordinate with relevant departments and deal with all kinds of objections in a timely manner.
