API standard 650 carbon and low-alloy steel tanks roof manholes

API 650 storage tanks API standard 650 carbon and low-alloy steel tanks are only suitable for containers that can evenly support the entire bottom and containers for non-refrigerated equipment with a design maximum temperature of 200 degrees Fahrenheit. It API standard 650 carbon and low-alloy steel tanks requires a minimum thickness of 3/16 inch. Other characteristics of the API 650 storage tank are: it is composed of carbon steel, austenitic duplex stainless steel and aluminum.

Sand blasting and derusting of API standard 650 carbon and low-alloy steel tanks uses compressed air as power and SiC, pomegranate sand and quartz sand as spraying materials to form high-speed jet beam, which is used to remove rust and dirt on the surface of metal storage tank and improve the binding force of workpiece with coating and plating material. Sand blasting is often used in API standard 650 carbon and low-alloy steel tanks construction.
