Triad bellows stocks special flanges to mate with most major engine manufacturers exhaust manifolds and turbo chargers. Floating flanges are standard for Caterpillar, Cummins and Detroit / MTU exhaust expansion joints. For Waukesha engines we have developed a 25% heavier lip flange manufactured in high temperature T321 stainless steel. This heavy duty lip flange prevents pre-mature fatigue cracking sometimes experienced with OEM expansion joints. All expansion joints can be manufactured to any length that best suits the available space. Any weldable fitting can be attached to the outlet side of the bellows to make the installation quick and easy. Manufacturing custom expansion joints is our business, let us know how we can help.

Triad Bellows designs and manufactures metal bellows and metal bellows expansion joints in accordance with the Expansion Joint Manufacturers Associations latest 10th Edition standards.  Bellows design calculations are provided with each quotation.  All expansion joints manufactured with tie rods are designed to withstand the full pressure thrust load. At Triad Bellows our goal is to provide innovative, cost saving designs without sacrificing quality and never taking shortcuts.
