Software plays a key role in implementing an Integrity Programme for bolted connections, Hydratight pioneered the use of software to support bolting applications over 10 years ago. Using the combined skills of our Technical team and In house software development team we have continued its development based on user feedback, technology advances and our roles on Industry standard committees. Our recommended bolt loads for standard joints are derived from independently verified calculation methods and traceable back to standards. Today, Hydratight has the most comprehensive suite of joint integrity software available.

Hydratight BoltUp® is our free bolt load calculator, delivered over the web or available as a mobile app. It has been reformatted to permit ease of use while retaining the Informate Calculation Engine. Boltup is now focused on Carbon Steel Weldneck ANSI B16.5 flanges, with selected lubricants and gasket options.
