ASTM A234 pipe API standard 650 duplex stainless steel tanks

In cylindrical tank walls, the longitudinal weld joints in adjacent shell courses, including compression ring welds, shall be offset from each other a minimum distance of 12 in. The butt-weld around the periphery of a thickened insert plate, or the fillet weld around the periphery of a reinforcing plate, shall be at least the greater of 10 times the shell thickness or 12 in. from any butt-welded seam or the bottom-to-shell or roof-to-shell joint. As an alternative, the insert plate (or the API standard 650 duplex stainless steel tanks reinforcing plate in an assembly that does not require stress relief) may extend to and intersect a flat-bottom-to-shell corner joint at approximately 90 degrees.

Standard API 650 tank calls for calculations based on the specific gravity of the liquid product being stored. This permits the thickness of the steel API standard 650 duplex stainless steel tanks needed as well as other specifications of how the tank is built to be determined by the weight of the API 650 tank.

Square hollow section S355J2H to Turkey. In January of 2015, our customer from Turkey chose us as their supplier of seamless RHS EN10219 S355J2H with a trail order of 120 tons. They required DNV test for the MTC and each tube. DNV inspector tested all the tubes and MTC. When our customer received the reports, they gave us a second order of 852.5 tons. Since then we maintain a long time cooperation relationship.

The coating on the outer wall of API standard 650 duplex stainless steel tanks can not only reflect light but also prevent corrosion. Different coatings for oil tanks have different reflective properties, and the reflective performance of coatings is expressed by reflection index. For example, the reflection index of white coating is 90.0, that of sky blue coating is 85.0, and that of light gray coating is 57.0. It can be seen that the white coating has good reflective performance, and coating the outer surface of API standard 650 duplex stainless steel tanks with white coating can reduce the evaporation consumption of the oil tank.

Our company will accept the product quality objection registration record, pass it to the API standard 650 duplex stainless steel tanks production unit and relevant departments, and timely coordinate the supervision of product API standard 650 duplex stainless steel tanks quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
