Possible without altering the design of the vessel (thickness),because the maximum allowable design stress for most materials is the same for any design temperature up to 650 ambient temperature tanks Allowable Design Stresses#176;F However,the pressure ratings for ANSI B16.5 flanges does change at temperatures below 650 ambient temperature tanks Allowable Design Stresses#176;F,and increasing the temperature to 650 ambient temperature tanks Allowable Design Stresses#176;F may necessitate upgrading the Maximum Allowable Stress Values ASME Pressure VesselFor example,if a 60,000 psi tensile strength material is used,the Maximum Allowable Stress Value is 15,000 psi.Division 2 Governs the design by Analysis and incorporates a lower safety factor of 3.Thus,the maximum allowable stress value for a 60,000 psiMaximum Allowable Stress Values ASME Pressure VesselFor example,if a 60,000 psi tensile strength material is used,the Maximum Allowable Stress Value is 15,000 psi.Division 2 Governs the design by Analysis and incorporates a lower safety factor of 3.Thus,the maximum allowable stress value for a 60,000 psi

This standard is both a design code and a construction specification.The design code is based on allowable stress principles,not on a limit state basis.1.3 Design Pressure and Temperature.Tanks designed for storage at nominally atmospheric pressure must be suitable for modest internal vacuum (negative pressure).Gas Tanker - Types,Tanks,Re-liquefaction and Cargo The maximum allowable tank design pressure in the vapour space for this type of system is 0.7 barg; (where the cargo is carried at ambient temperature),the tanks may be designed for a maximum working pressure of about 18 barg.For a semi-pressurised ship the cargo tanks and associated equipment are designed for a working pressure of Designing storage tanks - DigitalRefiningS is the tank wall material allowable tensile stress for the operating or test condition.CA is the corrosion allowance,if any.API 650 storage tanks are often designed to work at temperatures of up to 500 ambient temperature tanks Allowable Design Stresses#186;F (260 ambient temperature tanks Allowable Design Stresses#186;C).For these higher temperature designs,the allowable stress of the material decreases.

Mar 01,2007 ambient temperature tanks Allowable Design Stresses#0183;The design temperature you mentioned makes no difference for the mechanical design,the allowable stresses will remain the same for 20 or 50 deg C,so you may extend the design condition to 50 deg C.However,you have not mentioned anything of the process fluid,where the 20 or 50 deg C might make difference (any chlorides around?).Design Strength,AD2000 Merkblatt code - Boiler and I think that for the K-value at design minimum temp (i.e.-190 C) you need to use the value of K at ambient temperature.Typically these are the same - that's how most codes deal with design strength or allowable stress at temperatures lower than those listed in the codes.Design Pressure - an overview ScienceDirect TopicsThe temperature ranges allowable for the Class III hydrogen storage vessel are from 54 to + 85 ambient temperature tanks Allowable Design Stresses#176;C ( 65 to + 185 ambient temperature tanks Allowable Design Stresses#176;F).These temperatures are generally recognized as the extreme ambient limits to which vessels would be exposed during transportation or operation.
