Engine / Exhaust Products

Flex-Weld, Inc. / Keflex™ engine and exhaust bellows are the most reliable in the industry. We offer a 5 year extended warranty for the products we design. We will perform complete engineering take-offs on all new and refurbished ship exhaust systems, including expansion joint selection, location, quantity, and system configuration. We have exceptional expertise in our multi-ply thin-wall bellows construction with proprietary convolution shape. This combination provides our bellows with extended fatigue resistance and cycle life.

Our bellows can be manufactured from a wide range of alloys including T-321 high temperature-resistant stainless steel, T-316L corrosion-resistant stainless steel, or Inconel and Monel alloys to preclude salt water and chloride corrosion. Our metallurgical department will analyze failures and engineer a suitable replacement.
