I do not have a copy of Section VIII, Div 2 and have been given a support lug review done using a FEA analysis. The stress values presented are given as Von Mises stresses. How does one compare these stresses to the allowables in Section II Part D? Does the ASME code use Von Mises or Tresca...

Stanier, At this time we would like to avoid lined pipe.

Sorry, root should be route.

Thanks for the reply. At this time we do not want to go this root.

I am currently looking at an application using a dilute sulfuric acid slurry with a pH of less than 1.5. The process may reach 500F and 700psig for extended periods of time. I am searching for a cost efficient piping material for this application. Today a large range of products are...

We are looking at generating 650psig steam using a kettle reboiler and a thermal fluid heater as the heat input. I am looking for a published water quality specification for the reboiler feed water to follow. I am aware of the ASME water quality specification for water tube boilers and if I can...

In Appendix II of ASME B31.1, a method for determining the pressure at the discharge elbow of a relief valve is presented. In this equation, II-2.2.1, one is required to use the "stagnation enthalpy at the safety valve inlet". If the relief valve is on a steam accumulator designed for steam at...

I am looking for a design guide for venting two safety relief valves into one common vent pipe. If you know where to look please let me know.
