ECUTEC Mock-Up Exchangers

ECUTEC Mock-Up Exchangers

Fully Customizable Tube Mockups


Mock-up exchangers, also called tube mockups, tube bundle, exchanger test bundle, eddy current test bundles or tube testing bundles are used for training and testing purposes. They can be designed to incorporate any testing method like eddy current (ECT), RFT, IRIS, ECA, MFL, NFA, NFT, PSEC, ASME, etc. Available in lengths as small as 12” (400mm) to as long as 10 feet (3m). Test bundles have ranged from as few as 4 tubes to as many as 100 tubes with a customizable amount of support plates. 

ECUTEC mock-up exchangers are also easily maintained. They are designed for ease of tube removal for when a tube needs to be pulled for replacement, demonstration or maintenance purposes. They can be designed to be covered if OD defects need to be hidden from the people being tested. Additionally, ECUTEC makes covers that are removeable in case the tubes needs to be replaced or maintained. Frames can be provided alone or frames with any type of tubes, with and/or without machined defects. Customized carry cases can be supplied for transporting your Mock-Up, with optional wheels to facilitate transportation.
