 Polytetrafluoroethylene (PTFE) Hose Assembly |
.jpg)
PTFE hose assembly composes of PTFE inner tube, stainless steel reinforced out layer and end fittings. The hose has excellent properties of aging, anti-corrosion, pressure resistance, high and low temperature –resistance and light weight. It can be used as conveying conduit for hydraulic and pneumatic medium, lubrication and fuel system. It is broadly used in aircraft, airspace and astronautically industries. It conforms to the national military standard of GJB 2837-97.

| PTFE Insulating Water-drawing Tube |
.jpg) PTFE insulating water-drawing tube is made from PTFE dispersion resin and is prepared by the technology of paste extrusion. The tube gives good insulation property, excellent resistance to virtually all chemicals, high temperature and aging with a light-weight body. It can be used as insulating water-drawing tube of cooling water system for turbo-generator with inner water-cooled stator and stainless steel wire reinforced PTFE inner tube for rotor under the condition of the temperature of ＜85℃ and the pressure of 500 kpa. It conforms to the enterprise standard of Q/GHAD 23-2000.
