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 EJMA (Expansion Joint Manufacturer's Association), 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. It is a stand alone application for Windows operating systems. Bellows are calculated according to two editions of EJMA (Expansion Joint Manufacturer’s Association), ASME B31.3 Appendix X and ASME XIII Division 1 Appendix 26. It is very user friendly with full error checking for data entry and can therefore be used by a salesman or any other person who has some knowledge of compensators.

No extrapolation of factors or material values is needed. Everything is included in the program.

Bellows Master II is available in standard form and customized for a bellows manufacturer. Customized version includes manufacturer's tools, special bellows shapes and any other requirement manufacturer wishes to include. Using this fully customized program you will not be able to design a bellows your company cannot produce. For those who use hydro forming the program calculates required forming pressures, ram forces and tool settings including required material cut lengths and widths.

The program has an installation program and very large help file.

Bellows Master II has its own dedicated support page.

Bellows Master II EN

is a bellows calculation program. It is a stand alone application for Windows operating systems. Bellows are calculated according to EN 14917, which is the latest European standard for expansion joints. It is similar in style to Bellows Master II and is also very user friendly with full error checking for data entry and can therefore be used by a salesman or any other person who has some knowledge of compensators.

No extrapolation of factors or material values is needed. Everything is included in the program.

The program has an installation program and very large help file.

 

RecBel

is a program to calculate rectangular bellows to EJMA design code suplemented with possibility to calculate ferritic bellows elements without expensive fatigue testing. For austenitic bellows elements designer has option to use his own fatigue test results, EJMA round bellows published values with additional safety factor or combination of the two. For ease of use the program has the same user interface as our Bellows Master II.

This program is for Windows. The program has an installation program and large help file.

ThickBel

is a program to calculate thick bellows element to ASME VIII Div 1 Appendix 5. Program is fully analytical and therefore it is easy and fast to use. Alternative options are complex and expensive FEA or some of the full pressure vessel design programs that include similar module. Bellows manufacturer can now cheaply and easily optimize the thick wall bellows to suit their manufacturing capabilities. Four different bellows shapes are included in to the program.

This program is for Windows. The program has an installation program.

AxMov Tool

is a program to quickly calculate bellows' required axial movement due to thermal expansion of a pipeline or vessel. It also calculates recommended pre-setting of the bellows if the pipeline's metal temperature during erection differs from 20 C.

This program is for Windows and it has its own help file and an installation program.

HinMov Tool

is a program to quickly calculate bellows' required angular movements in a 3 hinge system due to thermal expansion.

This program is for Windows. The program has an installation program and its own help file.

Flange Tool

is a program to calculate oval and round flanges used for universal and gimbal compensators. Flanges can be blind or with a centre hole and both types may or may not have flange bolts. The program is easy and fast to use. Results may be slightly conservative compared to finite element methods but are faster and cheaper to produce. Intended users are estimators, sales and designers. It includes calculation of the bellows' pressure force and allows you to include external additional loading of the rods attached to the flanges.

This program is for Windows. The program has an installation program.

Pin Master

is a program for bellows hinge pin calculation. Program is easy and fast to use. It includes calculation of the bellows' pressure force and allows you to include external additional loading of the pins.

This program is for Windows. The program has an installation program.

Rod Master

is a program for bellows' control rod calculation. Program is easy and fast to use. It includes calculation of the bellows' pressure force and allows the inclusion of external additional loading of the rods.

This program is for Windows. The program has an installation program.

Gimbal Master

is a program to calculate two types of gimbal rings used in compensators. The program is easy and fast to use. Results may be conservative compared to finite element methods but are faster and cheaper to produce. Intended users are estimators, sales and designers. It includes calculation of the bellows' pressure force and allows you to include external additional loading of ring.

This program is for Windows.The program has an installation program.

Bracket Master

is a program to calculate various types of restraining bar brackets for compensators. The program is easy and fast to use. Results may be conservative compared to finite element methods but are faster and cheaper to produce. Intended users are estimators, sales and designers. It includes calculation of the bellows' pressure force and allows you to include external additional loading of the brackets.

This program is for Windows. The program has an installation program.

HeatTool

is a program to calculate bellows element's metal temperature in high temperature applications. Codes require use of fluid temperature for the design if the actual metal temperature is not established. Using HeatTool program the designer can use more realistic metal temperature and substantially improve the design. Program can be used also to check that the metal temperature is not below the sulphuric acid dew point. The program is easy and fast to use.

This program is for Windows. The program has an installation program.
