Need help finding the right tool?

ESI’s Flange Tool Master and EZ Calc work together to simplify flange maintenance and bolting decisions for pipeline professionals. The Flange Tool Master helps you instantly match flange spreaders, alignment tools, and nut splitters to your flange size, pressure class, and bolt condition, while EZ Calc calculates torque, grip length, bolt load, stud length, and nut size to recommend the right bolting tool. Together, they deliver fast, accurate, standards-based results—giving you a complete digital toolkit for flange separation, alignment, and bolting.
