API standard 650 welded tanks for oil storage reinforcement and welding

The finned tube heating device for high temperature heat transfer oil for large API standard 650 welded tanks for oil storage has the advantages of convenient inspection and maintenance. The high-efficiency fin heating coil assembly is composed of spirally arranged finned coils. The fins are mainly arranged in the straight pipe section, and the whole assembly is supported by several angle steel supports. The high-efficiency fin heating coil component can enter and exit from the manhole of the API standard 650 welded tanks for oil storage, which is convenient for maintenance and repair.

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 standard 650 welded tanks for oil storage 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.

The API 650 is widely used for tanks designed to withstand low internal pressures, for the API standard 650 welded tanks for oil storage storage of typical products such as crude oil, petrol, chemicals and water. We have extensive experience when it comes to API 650 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3.
