I'm sure there will be a few biased comments here, but can anyone please advise which is the best pressure vessel design software. As a minimun the software must be able to design to ASME VIII div1 & PD5500. All other codes will be a bonus. Eg Stoomwezen, AD-Merkblatter, TEMA With everyone's help we might be able to do a pro & cons of each sofware. A comparison of costs, usability, design coverage etc etc Appreciate everyone's advise. Thanks RE: Best PV Design Software (Mechanical) 5 Jun 03 11:14.

I have used PVElite for full vessel analysis and Codecalc for component analysis for a number of years. It does support the codes that you mention. It also support pre 1999 ASME stress values.

It is available from COADE.COM Another program which is of equivalent capability is COMPRESS. I do not know thier web site, but they are based in Houston. These programs are for mechanical analyisis only. If you are doing thermal design, you probally will need a different program. RE: Best PV Design Software. Hi Chiller (Mechanical)and hiliter (Mechanical) Take a look at Photo Gallery on The Home for 'COMPRESS' is COMPRESS Take a look at the brochure Click on the link to the left to download a copy of the COMPRESS 6 Demo, which has the following limitations: only 60' and 120' ID shells and 5' and 10' nozzles are allowed.

Besides those two limitations, the demo version is fully capable. The demo version includes both Div 1 and Div 2. COMPRESS is a true 32-bit Windows 98/NT/2000/Me/XP application, the world's most internationally recognized program for ASME pressure vessel design and analysis. COMPRESS considers ASME section VIII Division 1 and Division 2.

It is used by fabrication shops, process plants, engineering companies, end users and consultants. COMPRESS considers internal and external pressure; wind, seismic and other external loads; nozzle design and various support types. Properties for all of the ASME materials and AISC structures are in the program. Many help screens and user-error traps are included.

A vessel design wizard takes user friendliness to the next level. By supplying minimal vessel details, users can build standard vessels more quickly than ever. Also, the vessel details can be saved to build libraries of template vessels and any current vessel file can be converted into a wizard template file. Yet with all its power and flexibility, COMPRESS is very easy to learn and use. The report is written in HTML format --the language of the Internet.

Hotlinking allows you to 'surf the report' to quickly find calculations supporting a given result or to find the limiting condition for a thickness. Users can specify an expanded report to see all the details or a shortened report showing just the bottom lines. You can save the report in a self-expanding exe file transmittable by email. The recipient does not have to have COMPRESS to read the report. You can use Adobe Acrobat to generate the report in pdf format, not only electronically transmittable but also capable of being edited by you and notated by your customer.

Unfortunately, though, there are limitations to all the software currently available as they do not cover all aspects of pressure vessel design, especially where end user specs have their on little quirks. Sometimes it will be necessary to generate manual (or spreadsheet) calculations to cover uncommon configurations. You will not get one package that will successfully cover all aspects of the design you may require. Regards John RE: Best PV Design Software (Mechanical). Hmmm, looks like there are only two contenders!!! I use finglo at present, its reasoanably flexible but lacks the clarity and usability one would expect from software of nowadays.

Which is why, I'm looking at alternatives. I have downloaded the demo for compress and will take a look at it very soon. Apart from ASME, does this software cover other design codes? I too do a lot of spreadsheets and mathcad programs, but like you said, its normally the clients who dictate the design. Anyway no software will ever replace the human mind. However, with all these fancy software around, I just hope that a computer operator doesn't class himself as a engineer. RE: Best PV Design Software (Mechanical) 12 Jun 03 10:13.

I had mentioned in my previous reply that the Coade and Compress software was specifically for mechanical design and analysis. Prior to these programs being developed, the industry leader was B-Jac. This software can do thermal and mechanical design of heat exchangers,and prepare cost estimates of each option. I am not a user of this software, but I believe it is an industry leader. B-Jac has been purchased by Aspentech and information is available from I would be interested if there are any users of this software, and what feedback you might have. Have a nice day. RE: Best PV Design Software (Mechanical) 23 Jun 03 15:52.

PV Elite is good software for ASME DecVIII Div1 vessels. But for DIV2 and PD5500 it has many limitations. If the simple vessels needs to be designed this in undoubtedly the best as the user interface is very simple. However due care has to be taken in some of its module i.e. Saddle design for a long and heavy vseesl where the saddle supports needs to be stiffened by rings, this do not support this feature.

Similarly while dealing with PD5500 module in Nozzle calculations it gives some abnormal results. Finglow on the other hand gives accurate results but it is not that used friendly. I don't know if in latest version of finglow some GUI and better user interface have been added. Ab RE: Best PV Design Software (Mechanical) 27 Jun 03 07:56.

Why no mention of Whessoe's PVE5 software? It covers PD5500 and ASME VIII Div 1.

Tubesheet Design to PD5500, TEMA R,B and C. Also Flange Design is covered to either PD5500 and ASME VIII with additional TEMA rules also. Local Loads are covered to PD5500 and WRC107/297. Wind aand earthquake loadings are catered for. The software is user freindly, accurate and based on the Whessoe group's experience in designing pressure vessels since the turn of the century. RE: Best PV Design Software (Mechanical) 29 Jun 03 11:56.

Sometimes the software selection is dependent on the client preference and vailability of it at their location. But if we review from the consultants angle, thepopularity may be on the basis of usage in a particular country. In India we may list the popularity in the following order; PVElite, CoadeCalc, COMPRESS, Advanced Pressure Vessel COMPRESS alongwith their other modules like TEMA Heat Exchanger, ASME Heat exchanger has started getting the user attentions. Left to me, I will rate COMPRESS the best, economical, fast in updates. RE: Best PV Design Software (Mechanical) 18 Jul 03 20:53. The question simply asked: what software is appropriate for PD5500, ASME Div1, TEMA and any other codes. The issue of cost was also raised.

If that is the question, then the answer should be framed accordingly. Firstly, PD 5500 is important to those wishing to enter the European market, being able to compete of a level footing with the design methods used there. Performing calculations per this code can be extremely tedious, especially nozzle reinforcement, and even head thicknesses, as simple formulae are not used. There are a number of software packages that do this type of analyis which have been mentioned by others replying to the question (remember the question). Compress does not perform PD 5500 calculations, and performing tubesheet calculations to TEMA requires the purchase of an extra module. The same applies to Finglow which also involves the purchaser in buying the programme module by module.

Also, these days, fatigue analysis is required for risk analysis, although this point was not part of the question. As far as costs are concerned, the basic packages run fairly close to one another ($4000 to $5000 ballpark). However, what does the basic software include?

Much of the software requires the purchase of additional modules each increasing the cost of the software and maintenance. What software is sold with everything complete all in one package. Well PVElite does, plus the fact that it performs analyses to ASME Div 1 & 2. PD 5500, TEMA and also will perform fatigue analysis (to PD 5500). The choice of any commodity is based on cut, fit and style.

That is how we buy shoes and cars. It probably applies to software. I use PD 5500 frequently, and it is being called for more and more by those interested in the European market. RE: Best PV Design Software (Mechanical) 29 Jul 03 11:05. Chiller, I know PVElite does the design per PD 5500 and ASME Sec VIII Div 1,2, TEMA. But, check their website,. They have a working demo, user testimonials, design capability, sample output, pricing.

Before your decide, try the demo of all the programs you are considering and model a real job on them. This will give you first hand experience with the software. Ab1234, contact COADE's technical support, they are good in replying promptly. Check their latest versions, may be these issues are already addressed.

Regards, Mandy RE: Best PV Design Software (Chemical) 31 Jul 03 12:29. Epicure Software Download here. Chiller, I agree with Mandy that it is important to try all programmes before purchasing. We have PVElite and PVE5. We bought the PVElite for some ASME work and it is very good. However it does have gaps in the PD5500 and is not as good as the PVE5 for that code. Demo's are one thing but I would recommend taking the programmes on for evaluation that is why we went to CEA they gave 30 days of both programmes for a very reasonable fee and helped us with rentals of programmes for other codes. We have used CEA in UK, Holland and france but they do have offices elsewhere.

Their site is. Try it before you buy it.
