API Std 650 open-top tanks restrictions on stiffening rings

Above-ground API 650 storage tanks (vertical cylindrical flat-bottomed storage tanks) allow the storage of large volumes of goods at low cost. The only limitation is that they API Std 650 open-top tanks can be used under atmospheric pressure or relatively small internal pressure. There are different specifications and standards for the design of API 650 storage tanks.

As we know, the vertical metal tank, API Std 650 open-top tanks is welded by many components, and the welding quality of each component determines the later use effect of the API Std 650 open-top tanks. Professional API Std 650 open-top tanks manufacturers should have a set of professional skills in the welding process of API Std 650 open-top tanks. Key points for weld inspection of vertical metal tank, API Std 650 open-top tanks:
1. It is strictly forbidden to paint the welds before passing the inspection.
2. Visual inspection shall be carried out for welds.
3. NDT shall be carried out on the weld.

Impact Tests for High Alloys
Impact tests are not required for oil steel storage material nickel alloy welds made with electrodes/filler metals covered by AWS Specification A5.11 or AWS Specification A5.14, provided the nominal nickel content is 50% or greater, and the weld is deposited by the shielded metal-arc welding (SMAW), gas metal-arc welding (GMAW), gas tungsten-arc welding (GTAW), or plasma-arc welding (PAW) processes. When A5.11/A5.14 specifies the nickel content as a “remainder,” the nickel content shall be determined by summing the maximum specified values of the other elements (use the average specified value for elements with specified ranges) and subtracting from 100%.

The company's sales department has a professional team, they have professional steel knowledge, respond quickly, with the problems raised by customers can quickly give solutions, put the interests of customers first. With their own professional knowledge to provide customers with high-quality steel plate in line with the requirements. At the same time, in terms of price, we also have great advantages. Members of the business department make sure that the delivery time is short and the service is the best.

The company has huge steel API Std 650 open-top tanks products stock all the year round to meet the urgent needs of customers. For stock products, we can arrange delivery within 3 days. The transportation department and shipping department shall coordinate and follow up to update the progress to customers regularly, i.e. where the goods have arrived, so as to let customers not worry and rest assured.
