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. 

All programs have high quality printouts of the calculation input and output. Company's logo can be included into the prints. All reports can be directly saved to PDF.

All programs have Help files and are designed for Windows operating system.

Programs are updated constantly to keep up with the changing design standards. All good improvement proposals are always considered and added to the programs where found beneficial. Main programs have over 20 year history.

Bellows Master II is a bellows calculation program. 

Bellows are calculated according to two editions of EJMA (Expansion Joint Manufacturer’s Association), ASME B31.3 Appendix X, ASME B31.1 Appendix P and ASME XIII Division 1 Appendix 26 and ASME XIII Division 2.

Program 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 EN is a bellows calculation program. 

Bellows are calculated to two European standards. The first is EN 14917, which is the latest European standard for expansion joints. The second is pressure vessel standard EN 13445-3. Program 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.

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. 

Having ThickBel 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.
