MEDICAL BELLOWS, COOLING COILS and FLEXIBLE TUBING
- Blood Heat Exchangers
- Adult/Infant Oxygenator Bellows
- Coronary Perfusion
- Whole-body Perfusion Heat Exchangers
- Medical Grade Cooling Coils
- Flexible Metal Tubing
Manufacturers of Medical Devices must ensure they meet all national standards for safety and compliance in the country they wish to market their products. Different national legislative bodies such as the FDA, MHRA, TPD and European Commission all are united in their goals for the utmost in patient care and benefit, but they are not harmonized, meaning a product has to go through an approval process for each legislative body separately.
To support our customers in these different markets we maintain clean room manufacturing operations where the highest procedural levels of cleanliness are observed and validated to ensure ongoing compliance. All our components are assembled into medical devices prior to sterilization.

Vacuum Capacitors and Interrupters
Senior Flexonics designs and manufactures custom metal bellows for Vacuum Capacitors and Interrupters.
Vacuum Capacitors
Vacuum Capacitors are used in high voltage applications. This variable capacitor is used for many purposes that require tuning such as a matching network in the fabrication of semiconductor chips and flat panel displays. This unique design uses a high vacuum as its dielectric instead of air or non-conductive materials.
Some of the most common applications are antenna coupling, semiconductor wafer fabrication, RF matching circuits, Pulse shaping circuits, Power amplifier tank circuits, and for Non-magnetic circuits for MRI.
Vacuum Interrupter/Breaker
The vacuum Interrupter/Breaker acts as a switch with its contacts in a high vacuum. When the electrical contacts are separated it creates a vapor arc, which is quickly extinguished. Some typical applications for vacuum interrupters include: medium and high voltage circuit breakers, load switching, power transmission, power-distribution, industrial plants, and arc furnace applications. Vacuum Breakers are now being increasingly utilized at transmission class voltages. The vacuum interrupters in these breakers require considerably longer strokes i.e. open gaps as compared to those in medium voltages. Also the closing and opening speeds are higher. This requirement of longer strokes and higher velocity calls for a special design of bellows and the end components of the vacuum interrupters.
Vacuum Capacitor Bellows
Senior Flexonics copper plated vacuum capacitor bellows are used in vacuum sealed applications, primarily for impedance matching within an electrical system or network. They are ideal for hermetically sealed applications that require high voltage & high currents. These are also well suited for handling high frequencies. Our Material selection and Very High Elongation (VHE) bellows hydroforming process ensures the longest possible bellows stroke life for any given size. Our unique copper plating process produces an industry leading consistency in plating thickness over the entire bellows, including both crests and roots. This leads to higher reliability and also helps promote longer average bellows life. Masking of the copper plating on terminating ends of the bellows is also possible. Mating fittings can be brazed and leak tested on-site.

HVAC APPLICATION EXAMPLES:
Heating System Manufacturer
Senior Flexonics provides pressure resistant storage tank connections. These were developed to minimize heat loss with special insulated connections to meet the strictest energy saving requirements. These designs transport heating water quietly with minimal pressure loss. Also, our diffusion-proof design also prevents the entry of oxygen to protect the system against corrosion. All flexible tubing connectors were made available to complete the design for installation.
Building Water Supply
Drinking water pipes have to fulfil the strictest criteria. All water-carrying parts of the flexible Senior Flexonics water supply lines are made of standardized stainless steels with an extremely smooth inner surface ensuring maximum hygiene.
Gas Heaters
Gas heater gas pipes must be permanently safe. Senior Flexonics pipe components are made of corrosion-resistant stainless steel and are constructed individually. Senior Flexonics adapts the pipe components to the installation area of the corresponding system. These device side tube sections give the installer the exact flexibility he needs during installation to compensate for small inaccuracies without the need for on-site welding or soldering. This simplifies the installation and time.
Solar Technology
Weather-resistant connections optimally coordinate solar plants and building technology. Through our specially designed connections, solar plants and building technology work together perfectly. They are extremely temperature-resistant and equipped with a weather-resistant insulation. In this way, they compensate for thermal expansion and reduce heat loss to a minimum. All components are adapted to the specific requirements of your collectors. Installation then follows safely, easily and quickly.
The elements are pre-shaped according to your needs and provided with screw and plug connectors, as well as side ventilation. Special feature: The consistent development of hydraulically molded ends prevents any heating in the terminal area, which could result in a change in structure resulting in longer life and added safety.
Cooling Ceiling Systems

HVAC EXPANSION JOINT PRODUCT EXAMPLES:
Compensators and Flexible Connectors:
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.
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.
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
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
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.
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.
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.
Expansion Compensators
Expansion Compensators provide the inherent performance benefits and safety features of the externally pressurized expansion joint design in a compact package. Intended primarily for steam supply and condensate return lines, as well as hot and chilled water piping, this product is suitable for any small diameter axial expansion application.
Flexible Metal Pump Connectors
Flexible Metal Pump Connectors reduce stresses at piping connections to sensitive rotating equipment such as pumps and compressors. Capable of absorbing thermal growth, piping misalignment, vibration and noise, pump connectors offer extended service life for all rotating equipment.
Pipe Alignment Guides
Pipe Alignment Guides are an essential component of any properly designed piping system that employs expansion joints. These guides permit axial motion, while restricting lateral, angular and bowing movements. Learn more about Pipe Alignment Guides
