Metal expansion joints are critical components in heat exchangers. These joints ensure the reliability and longevity of heat exchangers, which are essential in various industries such as power generation, chemical processing, and oil refining.
Heat exchangers operate under high temperatures and pressures, leading to significant thermal expansion. Metal expansion joints accommodate these changes, preventing damage to the exchanger and maintaining efficient operation by providing flexibility and absorbing the expansion, vibration, and other movements. They also mitigate stress on pipes and other connected equipment, reducing the risk of leaks and failures.
To ensure that the critical components of unfired pressure vessels meet the necessary standards, the American Society of Mechanical Engineers (ASME) created the U Stamp certification. The U Stamp confirms a manufacturer’s adherence to the quality control system requirements outlined in the ASME Boiler and Pressure Vessel Code (BPVC).

Commitment to Excellence

The U Stamp accreditation is awarded to organizations that meet the stringent ASME standards for pressure vessel design, fabrication, inspection, and testing. These stamps differ from other QA/QC stamps as they are granted based on standards that a third party develops.
Teadit, a global leader in fluid sealing solutions, has recently achieved a significant milestone by receiving the prestigious U Stamp certification. With this certificate, Teadit has proven its ability to fabricate components and ASME Pressure Retaining Parts which follow the guidelines outlined in Section VIII of the latest edition of the BPVC.
The achievement of this accreditation underscores Teadit's dedication to maintaining the highest levels of safety and reliability in its products and processes. Not only do its products meet the highest standards of safety and performance, but it also ensures that its metal expansion joints are designed, manufactured, and tested to withstand the rigorous demands of heat exchangers and other pressure equipment.

Dedicated to Quality

Since 1970, Teadit has manufactured Metallic Expansion Joints and Flue Duct Expansion Joints whose main function is to absorb the movements and vibrations of a pipe compensating for dimensional variations. Its expansion joints are designed to the prescribed specifications for use in heat exchangers required by EJMA and ASME. More specifically, Teadit designs expansion joints according to ASME VIII and B31.3, and all its welders are certified according to ASME IX. It is also a member of the Expansion Joint Manufacturers Association (EJMA), a global association of leading expansion joint manufacturers and suppliers.
The hallmark of Teadit's manufacturing prowess is its comprehensive approach to product development. From initial design to final production, every stage is meticulously executed to ensure optimal performance and durability. Utilizing advanced materials and state-of-the-art manufacturing processes, Teadit crafts metal expansion joints that excel in withstanding extreme temperatures, pressures, and corrosive environments.
Moreover, Teadit's commitment to quality assurance is exemplified by its adherence to international standards and certifications. Its facilities are equipped with advanced testing capabilities to validate the performance and reliability of each expansion joint, ensuring compliance with rigorous industry regulations and customer specifications.
Teadit’s Metallic expansion joints allow greater flexibility and minimize pressure drop and energy loss, which then reduces design and installation costs. Teadit expansion joints can also be used as vibration isolators and, in some cases, to compensate for small duct or equipment installation misalignments.
