Flexible Metal Hose on International Space Station

01 May 13


US Hose Corp has developed special braided metallic flexible hose assemblies for use on the International Space Station. The hose will be part of the Nitrogen-Oxygen Recharge System, or NORS, which generates oxygen and nitrogen and stores them for later use.

Oxygen and nitrogen, which are necessary for crew consumption as well as system operations and experiments aboard the space station, were previously delivered to the space station by either NASA’s Space Shuttle or Roscosmos Soyuz vehicles. However, with the retirement of the Space Shuttle, there was a need for increased creation and recycling on board the ISS.

As part of the NORS these flexible metallic hose assemblies, developed by US Hose Corp, which will operate at some 6,000 psi working pressure (414 bar) and facilitate the creation of nitrogen and oxygen while aboard the space station.

According to Angel Vazquez, Director of Engineering and head of the project at US Hose Corp, “The hoses will have a 20 year lifespan aboard the International Space Station and will be a key component to the success of their continuing mission.”

“We have been working on this project for almost three years and are very excited to finally see the fruition of the hard work invested in the design stage, Vazquez added. “We are looking forward to completing this project as required and working on other space projects in the future.”

In conjunction with The Boeing Company and its Space Flight Awareness Program, it was arranged that Terry Virts, former pilot of The Space Shuttle Endeavor Mission STS-130 visited US Hose Corp on April 4, 2013. He was able to see firsthand how the hose assemblies are manufactured, assembled, tested with assured quality for their projected 20 year life span.

Virts, a Colonel in The US Air Force will be making the journey to The ISS at some future date and will lead in the installation of the hose assemblies in the NORS equipment.
