Expansion Joint Design Software Our expansion joint design software is mainly for companies and individuals who are designing or checking bellows or compensator designs. Bellows are calculated to, ASME and EN standards. Individual component design programs use generally accepted design formulas and our own proven proprietary calculations. These programs do not use the finite element methods and are therefore easy to learn and use.

Designs may be more conservative but are very fast to produce. Even a salesman who is not doing designs everyday can use them. All programs have high quality printouts of the calculation input and output. Company's logo can be included into the prints. We do not believe in having one large program. Such programs are nearly impossible to maintain and keep error free. Each of our programs is designed for a specific purpose, for ease of use, to be fast and reliable.
We are primarily design and consulting company and the software is developed based on our technical knowledge and experience. With our programs you the designer can design expansion joints that you need and not what some software designer assumed you need. Bellows Master II is a bellows calculation program.

Machinery 19 post s. Subscribe to this blog post Unsubscribe. Sa is the allowable stress from the applicable code. With bellows, design for an excessive number of cycles can unnecessarily compromise other design aspects, such as design with respect to internal pressure and column stability resistance to squirm.
Utilizing this program, we can easily perform all of the analyses noted above utilizing over 35 different materials including:. Response to Stress Question. This includes standard conversions in addition to constants used in calculations. Austenitic Stainless Steels Duplex Stainless Steels Nickel Alloys Copper Alloys Aluminum Titanium However, if you require an alloy that is currently not in our database, we will examine the alloy to determine it’s welding and ductility properties.
Click to Request Info. EJMA does not mention this. American BOA is often requested to aid customers in the proper selection of expansion joints for their particular system.
Historically, designers have put large factors of safety on the number of design cycles for bellows, which was in part justified since there was no design margin in the EJMA fatigue curve. Becht Software 4 post s. This would result in a margin of safety frse dependent upon the designer, and could vary from large, to none. Process Consulting 10 post s. And the allowale stresses can be different which different codes. When using this curve, it should be recognized that appropriate design margins are already included, and they should not fred be included in the specified number of cycles.
Was he fudging the first time? However, if you require an alloy that is currently not in our database, we will examine the alloy to determine it’s welding and ductility properties. Some common tests include the following:. American BOA uses a combination of 3D modeling software along with finite element analysis FEA to determine the correct hardware for your design conditions.
I cannot imagine that for simple applications the bellow tube Always has to be x-rayed or DPI tested. Benchmark table inputs and outputs have been revised, with material class and correction factor.
The distinction of thin versus thick bellows has been added.

stanvard It will also assist the user in communicating design requirements to the manufacturers and to properly install and maintain the expansion joint in service.
What is Bellows Pressure Thrust?
The software utilized for solid modeling and FEA work in conjunction with each other to allow the shortest possible time from concept standxrd to production drawing generation. The calculation of universal type Expansion Joints has been simplified by a modified equation for the axial movement per convolution. Becht Nuclear 36 post s.
The Tenth Edition standards combine the knowledge and experience of the leading manufacturers of expansion joints into an invaluable reference document. The design would be EJMA. Can this be true? Testing A large contributor to the knowledge base at American BOA has been the capability to perform in-house testing in our state of the art on-site test xtandard.
Perhaps there was confusion over which code was applicable.
AND it does not explain why his allowables don’t jive. This Guide is not intended as a source for expansion joint design or application details.
A new Fere version of the new 10th Edition Standards can be downloaded to your PC, laptop or tablet. Why was the EJMA stresses higher? This ensures your customized solution is not only fail safe but produced in a time frame that was previously not possible.
Bellows vendors will often quote two different cycle lives for their bellows. Fatigue life calculations were greatly enhanced and simplified. Chuck Becht on Wednesday, 16 October They seemed too high.

He is President of Becht Engineering Co. If a bellows can be manufactured from the material, we can easily add it to the database to perform your analysis. Available Positions Apply On-line. Single Bellows Axial Vibration Constants were revised.
