Quality control of API standard 650 floating-roof tanks

API 650 is an American standard for welding flat bottom vertical storage tanks. This API standard 650 floating-roof tanks standard specifies requirements for the design, manufacturing, welding, inspection and installation of storage tanks. API 650 is widely used in storage tanks designed to withstand low internal pressures and used to store typical products such as API standard 650 floating-roof tanks crude oil, gasoline, chemicals and water. BBN has extensive experience in API 650 tanks, from +/- 500 cubic meters of tanks produced in the factory to +/- 15000 cubic meters of tanks produced on site.

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 construction period comparison of mechanical cleaning and manual cleaning for vertical storage tank, API standard 650 floating-roof tanks. The API standard 650 floating-roof tanks mechanical cleaning period is short, and the construction period is not affected by the size of the storage tank and the amount of sludge in the tank, and the cleaning equipment operates 24 hours a day. The manual cleaning of the API standard 650 floating-roof tanks has a long construction period, which is easily affected by the external environment, and the number of workers is limited by the size of the storage tank and the amount of sludge.
