The construction of foundations for API 650 carbon and low-alloy steel tanks

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 API 650 carbon and low-alloy steel tanks most widely used and most commonly used standard for global storage tank construction and procurement is API 650. The Chinese translation name is "AP1650 Steel Welded Petroleum Storage Tank". API 650 storage tank is for commonly used oil, gasoline, diesel, chemical and production water storage, etc.

We participated the National Railway tender of Bangladesh with our local agent together, and won the 1000 tons corten steel sheets order. The corten steel sheets are used to make train carriage. We finished production of the 1000 tons corten steel API 650 carbon and low-alloy steel tanks sheets within 40 days, and arranged SGS test for the customer before shipment. The customer gave very high comments to our product and service quality, as well as fast delivery.

The hot weather in summer brings great security challenges to the vertical oil storage tanks, API 650 carbon and low-alloy steel tanks standing outdoors. We must find some simple and effective methods to protect the API 650 carbon and low-alloy steel tanks in order to make them safely spend the summer. As a API 650 carbon and low-alloy steel tanks manufacturer, in order to reduce the direct sunlight rate of the vertical oil tank, reduce the temperature change of the oil tank, and reduce the evaporation loss of the oil tank, we usually adopt the measures of applying sunscreen paint and washing with warm water.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, API 650 carbon and low-alloy steel tanks sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
