Choosing the right material for your metal bellows is essential. Non-ferrous metals are suitable for many sensing and actuation applications. Still, they can’t be used to handle aggressive chemicals or production lines that place a very high emphasis on cleanliness, such as the food industry. For applications in vacuum chambers, such as vacuum valves, pumps, or vacuum interrupters, the best solution is to use stainless-steel bellows.

Uses for Stainless Steel Bellows

Considering their multitude of uses, the importance of stainless-steel bellows are obvious. Stainless steel bellows are used for:

  • Precision bellows for volume compensators
  • Pressure and temperature sensors; altitude measuring in aerospace.
  • Flexible connectors (expansion joints); absorbing vibration and thermal expansion.
  • Metal bellows couplings: torsional (turning) moments can be compensated.
  • Bellows valves (gate valves, safety valves, or check valves); hermetic stem sealing simultaneously compensate the relative movements between the valve plate and housing caused by the opening and closing of the valve system.

Stainless steel bellows are an excellent solution for several problems in piping systems. Equipment movement, thermal growth, pressure pulsation, or vibration can disrupt the system and cause poor performance and damage. Stainless steel bellows help avoid these issues and keep performance levels high.

Why Use Stainless Steel Bellows

The importance of stainless-steel bellows is illustrated by the high costs of downtime associated with part failure. So, buying a higher-quality bellows is worth it compared to buying a catalog stainless-steel expansion joint. The design team at Triad Bellows designs your expansion joints for the ultimate in performance with no additional cost or manufacturing time.

Typical Industry Benefits

  • Easy Maintenance. Due to the chemical composition of stainless steel, the bellows or expansion joints are easily maintained and kept clean.
  • Readjustments. Stainless-steel bellows can also help resolve minor deviations in piping and reduce residual stress in the connection.
  • Wide applications. Stainless-steel bellows come in a wide range and design and sizes.
  • Good absorption qualities. Stainless steel is durable, flexible, and has excellent absorption qualities that allow them to absorb deformations caused due to thermal expansion and temperature changes.

At Triad Bellows, low pressure and high-pressure stainless-steel bellows are designed and manufactured in strict accordance with The Expansion Joint Manufacturers Association (EJMA) latest 10th addition. We believe that design integrity is key to manufacturing stainless-steel bellows expansion joints that will last. Customers worldwide rely on Triad Bellows for dependable metal expansion joint products engineered for maximum fatigue cycle life.
