Engineering
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.

Production
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).

Aerospace Quality Assurance
AS9100D certified means BSI meets new stringent aerospace industry requirements for product safety, risk based preventive action and prevention of counterfeit parts.

DFARS(Defense Federal Acquisition Regulation Supplement 52.225.7014) compliance for raw material origination intended to protect U.S. defense industry from being overly dependent on foreign sources of supply. We stock DFARS certified material in stainless-steel and high nickel alloys that are commonly used.

Manufactured in the U.S.A. to ensure quality and on time delivery commitment to our customers.

Four decades of operation and over a century of manufacturing expertise. Our engineers have the know-how to deliver precision parts for your demanding application.
