Bellows Systems has over the years worked together with our client’s engineering teams to develop aerospace bellows and other advanced aerospace parts for aircraft and rocket systems. We have extensive experience working with aerospace materials, including high nickel alloys.

Our experienced engineering and technical sales staff can support your engineering and sourcing teams with design and development of fit for purpose,flight critical bellows components in a timely manner. We take pride in taking on challenging engineering projects and developing solutions efficiently through the use of our in-house design tools, 2D and 3D CAD/CAM, finite element analysis (FEA), prototyping and proof of concept testing.

We have full capability to reverse engineer your legacy parts and manufacture to the latest part specifications.

Welding–We have aerospace qualified personnel and processes for welding (manual and semiautomatic GTAW and RSEW procedures) per,

  • ASME Sec IX Specification
  • AWS D1.1, D1.6, B2.1, D17.1 and D17.2.
  • MIL Specs

Our catalogue of over 150 qualified procedures includes various combinations of similar and dissimilar metals and alloys. Bellows Systems has semi-automatic seam welding capability for a wide range of tube diameters (> 0.75”) and wall thickness (>0.004”).

Testing–Our bellows inspection and testing includes dimension, nondestructive and destructive examination methods. All aerospace bellows products go through a full AS9102 dimensional first article inspection (FAI) and associated reporting. Our testing capabilities include,

  • Fatigue Life cycle testing (with or without internal pressure and temperature loads),
  • Leak testing (air under water),
  • Proof and burst pressure testing,
  • Spring rate testing with load cells,
  • Metallurgical and metallographic testing,
  • Visual examination (VT)
  • Radiographic Testing (RT)
  • Ultrasonic Testing (UT)
  • Dye Penetrant Testing (both visual and fluorescent PT)
  • Load to failure tests (Limit Load Tests).
