EN 10025 S355 plates API 650 carbon steel storage tanks

API 650 is the standard for welded tanks for oil storage. It specifies the design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 API 650 carbon steel storage tanks is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI, used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API 650 carbon steel storage tanks API 650 tanks with diameters between 8'-300', suitable for refineries, terminals, pipeline facilities and other customers.

The safety inspection of atmospheric storage tank, API 650 carbon steel storage tanks is divided into external inspection, internal and external inspection and comprehensive inspection. External inspection shall be conducted at least once a year, internal and external inspection shall be conducted at least once every three years, and comprehensive inspection shall be conducted at least once every six years. The safety inspection of large atmospheric storage tanks, API 650 carbon steel storage tanks requires special attention: the parts where the liquid level often fluctuates, the parts that are susceptible to corrosion, and the parts that are deformed and worn during use should be checked.

The company attaches great importance to the value of iron and steel, constantly improving itself in terms of attitude, innovation, human resources, etc., integrating the value of iron and steel into the company's philosophy, showing the spirit of fighting for API 650 carbon steel storage tanks iron and steel, forging iron and steel enterprise, creating steel market, establishing iron and steel team, and attaching importance to the sustainable development of iron and steel industry, so as to make iron and steel our permanent cause.

Thickness as it Affects Preheat and Post-heat Requirements
Plate with thicknesses below 1/2 in. is reasonably notch tough. In most steels, when the API 650 carbon steel storage tanks used plate thickness exceeds 3/4 in. – 1 in., notch toughness, particularly as welded, decreases sharply. The decrease in notch toughness can be minimized by the conventional post-heat treatment and, in many steels, by preheat treatment. The benefits of preheat treatment in steels 3/4 in. – 1 in. thick have been demonstrated; similar benefits could be expected in thicker steels, but sufficient experimental data are currently lacking.
