The nozzle loading data is Fx(N) - 56757 Fy(N) - 9989 Fz(N) - 1568 Mx(N.m) - 4150 My(N.m) - 24078 Mz(N.m) - (-14669) C.Min

Hi, I have a list of nozzle load (attached file) need to apply to the software but software input data is using Pr(N) Mc(N-m) Vc(N) ML(N-m) VL(N) Mt(N-m) Can help me determine which nozzle load data I need to input in? Thank C.Min

Hi, Which mean I need to choose using 12mm plate since the min thickness 10.35mm? How to account for the losses on thickness on the fabrication process? Is there any formula to including it? Thanks.

Hi All, If I using ASME VIII Code to calculate the 2:1 Semi Ellipsoidal Dished Head, ASME formula calculate out the minimum thickness is 10.35mm, so do I need use the minimum thickness time the safety factor 1.2? After time safety factor will be 12.42 and I choose using plate of 15mm. If not...

Dear All, Please help me on clarify below material whether is equivalent or not. BS S345 material equivalent to ASTM A36? Appreciate on your help. Thanks. C.Min

Hi, can someone please explain to me what is the different between ASME SECTION VIII DIV 1 Hydrotest pressure of UG-99(b) and UG-99 (b) Note [34]??

Hi, i have 2 question regarding on the half pipe jacket of a pressure vessel. i) For example if the pressure vessel have half pipe jacket with 0.49Mpa pressure, do I need to consider an external pressure in the pressure vessel?? ii) Normally if the vessel have a jacket,a jacket closure is...

Thanks for the info...really appreciate...

Actually how do we design spiral heat exchanger?? The spiral heat exchanger tube is buy from other supplier and install in (correct me if I'm wrong), so can I design the spiral heat exchanger by using the same method to design the shell and tube heat exchanger (fixed stationary)??

Hi guys, I quite new in pressure vessel this field. I got 1 question about the atmospheric pressure (atm pressure) actually is equal to 0 or 1 when using atm pressure to design a vessel??
