API 650 liquid-storage tanks EN specifications plates
API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API 650 liquid-storage tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.
The hot weather in summer brings great security challenges to the vertical oil storage tanks, API 650 liquid-storage tanks standing outdoors. We must find some simple and effective methods to protect the API 650 liquid-storage tanks in order to make them safely spend the summer. As a API 650 liquid-storage 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.
The hardness of the welds contacting these environments, including the heat-affected zones, shall be considered. The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API 650 liquid-storage tanks manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.
