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...
Colleagues:
A hypothetical question:
Construction Code ASME Section VIII, Division I, latest edition/addenda. A TEMA type BEM shell & tube, with single course construction of the shell. Shell size 6" IPS, out of SB-619 UNS N10276 Alloy C276 pipe. Design MAWP 75 PSIG + FV @ 325F, with a...
Other fabricators:
Just want to get a sense from others in the industry on how strictly this requirement is adhered to in general.
The reason I ask is we just started an Order where we are replacing the tube bundles in several heat exchangers, originally fabricated in 2008. The units are TEMA...
Have an application where we are replacing an existing piece of equipment in a piping system. Currently, the customer has 1" 150# flanges. He would like to not change any of his hard piping. He has requested that the equipment we are replacing have increased capacity over the original, should...
Background: We're evaluating the ASME VIII, Div.1 mechanical software from a very well known company. We have the full version of the program they currently have on the market, but for a limited time.
Yesterday I was rating some old jobs, comparing our calculations ('07 edition), to the...
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...
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...
