    CSA Z662 Manufacturing Mill Tolerance in WT Calculation

    I would like to understand why manufacturing mill tolerance is not required to be accounted for in the design wall thickness calculation in CSA Z662. CSA Z662-11 Clause 4.3.5.1 provides an equation that can be used to calculate design wall thickness. Clause 4.3.11.1 states that “the nominal...

    Location of Pressure Taps for Orifice Plates

    From some documents, I have read recommendations to use radius taps (pressure taps located at 1D u/s and 1/2D d/s of an orifice plate) with regular flanges in lieu of using orifice flanges for pipe size NPS 12 and larger. The same documents recommend using orifice flanges for pipe size NPS 2 to...

    Pipe Wall Thickness for Recip Applications

    Thank you for giving me some direction. I was not clear in my original question - The application is for process fluid (natural gas, produced water and hydrocarbon liquids). When I calculate the min WT required per B31.3, corrosion allowance of 1/8" was included in the wall thickness...

    Pipe Wall Thickness for Recip Applications

    I am a junior engineer in this field and just want to get more understanding behind piping specifications. To determine the pipe wall thickness to be used, the minimum wall for internal pressure can be calculated using B31.3, than most books ask to use the next pipe wall schedule. I noticed...
