Air Products has supplied the world’s largest autoclave with an advanced nitrogen (N2) system.

The system, supplied to Boeing’s new 777X Composite Wing Center in Washington, US, will be used to create the inert atmosphere and rapid pressure required to form and cure large carbon fiber composite wings for the aircraft manufacturer’s new 777X commercial jetliners.

Air Products’ nitrogen supply system installed at Boeing’s Composite Wing Center in Everett, Wash.

Under the scope of the agreement, the Tier One corporation also delivered three 15,000-gallon liquid tanks and a steam sparged water bath vaporisation system.

An autoclave is a strong heated container used for chemical reactions and other processes using high pressures and temperatures. Boeing’s assembled wings will be placed into the autoclave, which is then closed, sealed and flooded with the N2 at specific flow rates, pressures and temperatures to purge out oxygen (O2). This creates the correct atmosphere for the curing process.

Paul Householder, Vice-President – Western Region, Americas for Industrial Gases at Air Products, explained, “Boeing is a leader in their industry, and we are excited to build on our existing relationship by playing a part in the fabrication of the world’s largest carbon fiber composite wings for their newest commercial jetliner.”

This project represents the third major autoclave project that the industrial gas corporation has completed with Boeing in the last three years, but Air Products has been supplying the aerospace industry with its technologies for over 50 years.
