Title:
GAS IMPERMEABLE TUBE JOINT AND METHOD OF FORMING SAME
Document Type and Number:
WIPO Patent Application WO2005060612
Kind Code:
A3
Abstract:
A method of forming a gas impermeable joint (12) in a fluid system includes: providing a tube (14) having a metallic barrier layer (18) disposed between an inner plastic layer (20) and an outer plastic layer (22); forcing at least one of the inner plastic layer (20) and the outer plastic layer (22) into contact with a plastic surface (32, 34; 80) of a component (16); and welding the at least one of the inner plastic layer (20) and the outer plastic layer (22) with the plastic surface (32, 34; 80) to form the gas impermeable joint (12). The welding may include: spin welding, hot plate welding, vibration welding, and ultrasonic welding. The metallic barrier layer (18) extends substantially to the component (16), thus improving the gas impermeability of the joint (12) between the tube (14) and the component (16).
