API Std 650 duplex stainless steel tanks pivot-jointed pipe drains

Corrosion allowance, if specified, shall be added to calculated API 650 tanks shell and self-supporting roof thicknesses; to minimum nominal thicknesses of bottom and supported API Std 650 duplex stainless steel tanks roof plates; to nozzles and manholes; and to all exposed surfaces of internal structural members and non-removable internals.

Steel transportation because of the special material of API Std 650 duplex stainless steel tanks steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.

API 620 Steel Oil Tank Bottom and Shell Support
The tank API Std 650 duplex stainless steel tanks under-bottom insulation shall be designed to resist the combined pressures from the product load, the overturning seismic load and the vertical seismic load. These seismic pressures may be combined by SRSS.
The bearing ring under the shell shall be designed to resist the calculated OLE peak compressive force in the tank shell due to overturning (see API 650 oil tank, Section E.6.2.2), including dead and live loads. A 33 % increase in allowable bearing stress is permitted.
