Metal Bellows

Interactive Metal Bellows Expansion Joint Calculations

Design your own bellows to suit your application or check existing bellows. Metal Bellows design calculations which will give spring rates, stresses and cycle life - including default bellows profiles and movements. Ideal for consultants, designers and sales people.

World leading Non-Linear FEA program MSC MARC used in-house on bellows assessment. 30 years design experience and bellows characteristics testing contribute to the App.

Salesmen - The value of getting a sale is knowing your product and looking professional. Be able to assess a bellows on site. Instantly give design input to engineers. Gain valuable design experience.

Site Engineers - Check your bellows on site to validate movements and cycle life.

Consultants - Calculate spring rates and loads. Adjust the bellows design and view instant changes in results. Verify nozzle loads. Enter your own bellows convolution profiles.

Customers - Validate that the bellows you have bought conforms to your requirements. Check that the cheap imported bellows will do the job. Measure the convolution profile and see spring rates and cycle life instantly.

Inspectors - Has the supplier formed the correct convolution profile? Check the height and pitch to their calculations to ensure that the bellows will perform. 2mm smaller in convolution height can mean over one thousand less movement cycles and higher spring rates.

Manufacturers - Ideal for phone sales where information can be given easily by non-engineering sales people.
