Dear Engineers, For lug types with a bottom plate and no continuous rings (Simple geometry with no gussets and gusseted geometry with top plate in Lug Type), enter the distance between gussets plus two times the gusset plate thickness. For lug types with continuous top and bottom rings...

THANKS MIKE, that's why PV elite never put an error for different thicknesses but codeware compress never allows anyone to put different thicknesses.

hello guys, as per UHX14.2, the two tubesheets ( fixed and floating) shall have the same thickness and material. however in my case the design temperatures at stationery side is different (i.e. 500 deg. C) from what i am having at floating end (288 deg. C) and the tube length is 18000 mm from...

Is it possible to perform RT for the steam pipes size NPS 2 that are drawn from header in a fired boiler deisgned on Section 1

Dear All, I am right now looking for some pumps attached in parallel to a header I want to calculate the surge in startup of pump to cater the hammering in the header

Dear All, I am right now working on design and detail engineering of a header having tube ligaments on its already UG-53 has been used what if one of my ligament hole comes on a circumferential/longitudinal seam (All of the seams are 100 % radiographed) What will be the code requirement that...

hello guys, I want to know is there any method to perform the calculations as per TEMA and UHX for tubesheet in PV-Elite as this we can do in COMPRESS. With Best Regards Zain

i know it i need a sample comprehensive calculation

Can any one share sample mechanical design calculations for Air cooled Heat Exchanger for gaining knowledge in this field

then it must be used as good engineering practice to follow welding symbols as per AWS A 2.4

Dear Members, Good day, I want to ask that where it has been mentioned in ASME BPVC codes to follow AWS A 2.4 for the welding symbols on drawing for any stamped vessel Best Regards Zain

Dear All, I want to ask as While calculating WRC-297 calculations on PV Elite, Pv- Elite considers 2 Stress concentration factors mainly 1) Shell Stress Concentration factors (default value 1.2) and 2) Nozzle Stress Concentration factor ( default value 2.25) my question is that what values...

Guys, How are you all, I was yesterday designing a vessel having a transition cone, and while I was checking the calculation I came to know that compress takes the value of t in the fiber elongation calculations for cones and transition other than nominal thickness considered i am attaching the...

Mike Yesterday i was designing a shell and tube exchanger with AES configuration this error came, to eradicate this error i increased the the thickness of Fixed tubesheet from 150 mm to 200 mm and then error gone hence i am searching for the right solution this may lead us to avoid that useless...

This is wrt ASME S8D1 edition 2013 para UHX-14.5.9(b) which deals with checking the tubes for buckling stress in case of a floating head heat exchanger. Can anybody explain the reasoning/logic behind this para which is relevant for floating head shell and tube heat exchangers? As this para is...

thanks alot guys

So guys Any solution?

Slots extends from BCD to the outside diameter of the Flange and blind Flange as you can see in attached sketch

Dear All I am working on a design project that comprises of a quick opening closure having slotted bolt holes and instead of having stud bolts it has Eye bolts eye side of the bolt is attached to the shell so that we can instantly open all bolts i am having trouble in designing such type of the...

Jitin Thanks for your precious suggestion i think the error is still there i think an expansion bellow shall be used to avoid this error or we can ask client to revise MMT what you say?
