Features
Non Ageing Properties
PTFE has a total resistance to ageing and moisture absorption and is unaffected by outdoor weathering—outlasting rubber and plastic hoses which are stiffer and heavier and often more costly which degrade by chemical attack, temperature and weather.
Alternative Designs
A full range of alternative options are available either as standard or to suit each individual application.
PTFE Lined Fittings
Intergrally lined by continuing the convoluted tube through the end fittings and flared over sealing faces – producing an uninterrupted, step free flow of media. Ideal for “bug free” hygienic non contaminate applications. This design eliminates corrosion of standard unlined end fittings by strong corrosive media.
Universal Usages
In all aspects of industry Wuxing can solve hose usages in a wide variety of applications providing answers to a multitude of fluid transfer problems.
Temperature Range
-100 to +200℃ depending on grade,pressure and application.
Non Contaminating
PTFE transmits to taste,colour or contaminates into media complying to all food , Dairy,Pharmaceutical criteria.
Fatigue Stability
Wuxing is extremely flexible,with tight,kink proof bend radii,means shorter hose to take up severe bends than other hoses,making Wuxing cost effective. When compared to metallic hose so often subject to flexible fatigue ,pinholing and chloride stress corrosion in steam and other application problems. Daming does not suffer from these symptoms.
Applications Include
Chemicals Acids Nuclear
Paint Solvents Marine
Pharmaceuticals Breweries Petrochemicals
Food Steel plants Textiles
Steam Pulp and Paper Automotive
Tanker Hoses Dyeing Plastic
Tar and Bitumen Cosmetics Rubber Process
Drinking Water Medical Biochemicals
