ASTM A216 grade WCA external floating roofs API Std 650 uplifting 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%.

Compared with the fixed roof API 650 oil storage tank without API Std 650 uplifting tanks floating roof, there is no evaporation space. In principle, this eliminates the so-called "large breathing loss". Evaporation not only causes the loss of product quantity, but also affects the quality of API Std 650 uplifting tanks product and pollutes the environment.

In 30th,Dec,2018--2th,Jan,2019, One Malaysian customer come to visit our factory to inspect their goods about CCS-AH36 steel plate. This customer is a famous shipyard in Malaysia. Their company has the business scope of tourism, API Std 650 uplifting tanks shipbuilding, transportation and so on. As a terminal manufacturer, they have strict requirements on quality . After visiting our factory, the customer are very satisfied with the quality of this batch of products.

The main contents of safety inspection for atmospheric storage tank, API Std 650 uplifting tanks are to see whether the tank foundation is sunk, whether the tank is corroded, whether there are cracks in the tank body and bottom, whether there is concave convex phenomenon on the top and wall of the tank, whether the accessories of the storage tank are in good condition, etc. After the API Std 650 uplifting tanks safety inspection and detection, the defects found in the tank should be handled according to the inspection rules in time to ensure the normal and safe use of the storage tank in the later stage.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel API Std 650 uplifting tanks plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
