5154 aluminum bar API Std 650 aluminum storage tanks
Above-ground API 650 storage tanks (vertical cylindrical flat-bottomed storage tanks) allow the storage of large volumes of goods at low cost. The only limitation is that they API Std 650 aluminum storage tanks can be used under atmospheric pressure or relatively small internal pressure. There are different specifications and standards for the design of API 650 storage tanks.
High temperature heat transfer oil fin tube heating device for large API Std 650 aluminum storage tanks has the advantage of high heat transfer efficiency. The high-temperature heat-conducting oil finned tube heating device adopts high-efficiency outer finned tubes. The outer finned tube coils are immersed in a water bath. Compared with ordinary light tubes, the contact area between the evaporation coils and the medium is increased. The total heat transfer coefficient of the coil is determined by the heat transfer coefficient outside the tube. This increases the heat flux per unit tube length and improves the overall heat transfer efficiency.
We have a stable system and professional human resource management work as the support, from the six aspects of guidance, cohesion, incentive, constraint, radiation and stability, we continue to introduce, modify and train employees from concept to action, and shape employees through constant guidance of common values.
Inspection of Butt-welds in PipingButt-welds in piping and in API Std 650 aluminum storage tanks pipe fittings within the limitations of 1.3.2 (including the annular space of double- wall tanks) shall be inspected in conformance with API 620 oil tank standard Q.7.7.2 through Q.7.7.6. Longitudinal welded joints in piping that contains liquid shall be completely radiographed except for manufactured pipe welded without filler metal, 12 in. or less in diameter, which is tested hydrostatically or by eddy current to ASTM requirements.
