HVAC – Expansion Joint Product Selection Guide

Senior Flexonics is recognized as a leader in the metal expansion joint industry. Our leadership has been earned through consistent application of solid engineering principles, stringent quality standards and product innovation to produce safe and reliable metal expansion joints and flex connectors for HVAC piping and ducting applications.

HVAC Expansion joints compensators and flexible connectors

Normal Corr

Normal Corr expansion joints employ a standardized bellows design ideally suited for general industrial applications. Offered with flanges or butt weld ends from 3” to 48” nominal diameter for design pressures to 300 psig at 650°F. (Consult factory for larger sizes) Learn more about Normal Corr Expansion Joints

High Corr

High Corr bellows are hydraulically formed to produce superior fatigue life and maximum strength for severe service applications. This product provides an excellent means of absorbing large pipe motions (up to 7 1/2”). High corr bellows are available in two styles: Free Flexing and Controlled Flexing.

Free Flexing expansion joints are widely used in process and steam piping applications to 50 psig. In addition, the Free Flexing expansion joint is recommended for compressor connections, engine intake and exhaust piping, ventilation and pump suction or discharge lines.

Controlled Flexing expansion joints combine the Free Flexing bellows design with mated neck rings and control rings between each convolution. This rugged construction reinforces the bellows for higher pressure applications. With an external cover this expansion joint provides a high degree of safety for the most severe operating conditions. Learn More about Controlled Flexing Expansion Joints

Externally Pressurized Expansion Joints

Externally Pressurized expansion joints have a heavy duty packless design that enables this product to accommodate large amounts of axial motion at high pressure without the risk of bellows squirm. Limited to axial movement only, the bellows is fully enclosed within an outer shell which is constructed of standard weight pipe, offering the highest degree of protection for the bellows and personnel. External insulation may be added directly over the outer shell. This expansion joint design also permits direct burial. Consult factory for additional information. Learn more about Externally Pressurized Expansion Joints

Exhaust Flexible Connectors

Exhaust Flexible Connectors are designed for low pressure applications such as stationary and marine gas turbine, diesel engine exhaust, and low pressure ducting. Large motion capability, low spring forces and reduced weight make this product ideally suited for thin-wall duct systems. Learn more about Exhaust Flexible Connectors
