The foundations for API standard 650 aboveground welded storage tanks

The Charpy V-notch test shall be used, and the minimum impact value at the design metal temperature shall be as given in Table R-2. For subsize specimen acceptance criteria, see ASTM A20. An impact test temperature lower than the design metal temperature may be used by the API 620 welded storage tanks Manufacturer, but in such a case the impact values at the test temperature must comply with Table R-2.This API 650 tank standard is designed to provide industry with tanks of adequate safety and reasonable economy for use in the API standard 650 aboveground welded storage tanks storage of petroleum, petroleum products. and other liquid products.Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed API standard 650 aboveground welded storage tanks materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.Inspection of weld and micro crack of API standard 650 aboveground welded storage tanks: the inner and outer surface of API standard 650 aboveground welded storage tanks, weld and heat affected zone shall be observed by naked eyes first. 100% ultrasonic testing or 100% penetrant testing are carried out for butt welds of API standard 650 aboveground welded storage tanks. For the defects found by 100% magnetic particle inspection, dye detection, 100% ultrasonic inspection or 100% penetrant inspection, the radiographic inspection shall be used again to ensure the accuracy of the test results.Customer first, reputation first, high-quality and perfect after-sales service is the extension of our product value and an important guarantee for the interests of customers. The purpose of our API standard 650 aboveground welded storage tanks service quality management system is to establish and constantly improve a scientific, reasonable and efficient service quality management system, and complete the after-sales service quality guarantee work of customers fairly, accurately and timely, For our company's API standard 650 aboveground welded storage tanks customer service to establish a good, comprehensive, full service system.
