    Does the Circ Joint in a Flanged & Flued expansion joint require full X-Ray?

    We are getting some pushback from a Canadian safety authority in their review of our application for CRN on one of our straight tube HX designs. The design contains a simple flanged & flued expansion joint per Appendix 5 and TEMA. The flanged and flued heads we are using are small: 10-3/4" OD...

He has requested that the equipment we are replacing have increased capacity over the original, should...

    Tubesheet Design

    Early appology if this has been discussed before; I did several searches but was unable to find anything relevant. We have a customer who currently owns a shell & tube heat exchanger (TEMA NEN); he uses it more as a reactor vessel than a heat exchanger. He is looking to have his existing unit...

    Nameplate Consistency

    We are designing a vessel for a skid manufacturer here in the US. The owner is in Canada, so the vessel will carry CRN. After submitting the initial drawing, we received a revision request asking that the design temperature be shown in both SI(C) and US(F) on the nameplate. When we submitted...
