Bellows Systems’ Nadcap® Accreditation Makes Headlines in Aerospace News!

Bellows Systems, Inc. is making waves in the aerospace industry as we proudly announce our recent Nadcap® accreditation for Resistance Seam Welding and metallographic welding examination. What makes this achievement even more exciting is that the news is buzzing about it

In a recent press release covered by top-tier aerospace news outlets, we highlighted our commitment to continuous quality improvement and strict adherence to aerospace industry standards. Alpha Mahatvaraj, our CEO, expressed the significance of receiving Nadcap® accreditation, stating, “It demonstrates our ongoing commitment to continual improvement in quality. We remain focused on satisfying customer needs and delivering products in strict adherence to aerospace industry standards and specifications.”

Jay Solomond, Executive Vice President and Chief Operating Officer at the Performance Review Institute, emphasized the global recognition of Nadcap® accreditation as a hallmark of quality. He praised Bellows Systems for achieving Nadcap® accreditation for Resistance Seam Welding and metallographic weld examination, acknowledging the hard work and dedication of our team.

The coverage extends beyond the accolades to showcase our state-of-the-art purpose-built Resistance welding machines. These machines, capable of handling various diameters and materials, provide live feedback and post-weld reviews of numerous welding parameters, ensuring defect-free Aws D17.2 Class A, resistance welded joints.

Not only has our welding capability gained recognition, but our metallography lab has also earned its stripes. Accredited and fully equipped, the lab conducts all necessary non-destructive and destructive testing to ensure Class A welds. The facility boasts new sectioning, grinding, polishing, and inspection equipment housed within an environmentally controlled room.

About Nadcap®, created in 1990 by SAE International and administered by the Performance Review Institute®, this globally recognized accreditation showcases our commitment to quality, safety, and collaboration in the aerospace industry.

As we celebrate this milestone, we invite you to read more about our Nadcap® accreditation in the featured articles, and explore how Bellows Systems continues to set new standards in aerospace quality.

What is Hydroforming
January 29, 2019

What is Hydroforming?

Hydroforming is a metal forming process that swells the material into a die using a high pressure fluid. This forming process is a practical demonstration of Pascal’s Law, which states that external static pressure exerted on a fluid is distributed evenly throughout the fluid.

Hydroforming is a metal forming process that swells the material into a die using a high pressure fluid. This forming process is a practical demonstration of Pascal’s Law, which states that external static pressure exerted on a fluid is distributed evenly throughout the fluid. This allows us to form complex shapes like the convolutions on a bellows with a high degree of consistency.

Bellows Systems manufactures the widely known, Kopperman™ Bellows using this method. It is composed of a light gauge metal tube of one or more ply formed into a series of corrugations. Kopperman Expansion Joints can be manufactured with bellows formed from any material which has the necessary drawing quality, and the corrosion resistance required by the operating conditions of the system in which they might be installed. The standard Type 115 Non-Equalizing Expansion Joint utilizes a close-pitch single ply bellows. The standard Self-Equalizing Type 109 and Type 127 Expansion Joint utilizes an open-pitch single ply bellows. The pitch and depth of draw of any bellows can be varied and the shape modified to meet special application requirements. Multi-ply bellows are used primarily on small expansion compensators as standard equipment, and also on other large diameter Expansion Joints where significant reductions in compressive forces are desired. Extreme caution must be employed when specifying multl-ply bellows because they tend to be unstable under certain conditions. Torroidal bellows are very often used where extremely high pressure applications are encounterd.

What are Tie rods? Why do we need them?

What are Tie rods? Why do we need them?

Tie rods are devices, in the form of rods or bars that are attached to the expansion joint assembly whose primary function is to continuously restrain the full bellows pressure thrust during normal operation while permitting only lateral deflection.

Angular rotation can be accommodated only if 2 tie rods are used, located 90 deg opposed to the direction of rotation.
