        key words: YFLUO,   PTFE,   Fluoropolymer,   Fluorocarbon,   Teflon, xylan,   sermagard , sermalon;    , corrosion-resistant bolts, fasteners, bolts and nuts, bolt corrosion coating, special coated.
fasteners (bolts nuts and bolt) is a very old problem, has been in existence for the first time since the use of self nuts and bolts.   threaded fasteners is often a weak link in corrosion protection.     however, the corrosion of fasteners is often behoove, not fully consider the facilities corrosion protection standard specification. Many industrial (pipelines, chemical facilities) production manager said, they think that the corrosion problem of fasteners is not their major concern, but also did not consider the influence of the cost. Corrosion will cause the metal surface is uneven, for fasteners, the thread soon began to rust corrosion, metal transformation, which showed a reduced strength of threaded connection, can not be disassembled bolt and nut, which causes much trouble to repair and maintenance. Bolt corrosion caused by not removing will enable the repair time is prolonged, rising costs, particularly large bolt even need to use the split nut device or by cutting gun can be removed, for the petrochemical production, will undoubtedly make the security risk is greatly improved. Production equipment of
chemical enterprises are more or less a corrosion phenomenon, especially acetic acid, methanol, hydrochloric acid, alkali and other production enterprises and as a raw material production enterprise, the problem of corrosion is more serious. Brought the heavy replacement work and production cost and safety to the enterprise. So the corrosion problem is to present and future has been facing the problem of chemical enterprises, to let the leaders have a headache.
in today's chemical enterprises, mostly in a simple preservative to resist the corrosion, but not to play a fundamental role, such as: galvanized, hot-dip zinc, black, wipe the oil, the effect is not significant, frequent replacement in.
WINJOIN and the main global fluorine polymer production enterprise cooperation developed specially for use in petrochemical enterprise YFLUO fastener of anticorrosive coating, which can help you to solve the above problems and cost saving: the anticorrosion performance of
superior: YFLUO has superior anti-corrosion performance, compared to black, galvanized, hot-dip zinc phosphating, cadmium plating has not advantage of ASTM  B-117, salt fog time up to 6000 hours.
high temperature properties of coating can be at the temperature of -190 DEG C:   job +260 DEG C temperature range;
dry film lubrication: coating contains PTFE or PTFE containing molybdenum disulfide lubrication, double. Even in high load situations, coating not only is not easy to be destroyed, but can provide stable torque coefficient;
superior abrasion resistance and anti adhesion properties;
prevent dust adsorption and superior wear resistance performance;
weathering properties: weather, sun, saline environment, UV, such as
YFLUO anti-corrosive acid-base environment; coating market has now been the bolts in a wide range of application and promotion, especially in some international chemical companies, have been used as a standard to enter their supplier system, such as Dow Chemical, AKZO NOBEL, Roman Haas,   National Oilwell, Celanese, CNOOC, ConocoPhillips, Shell shell,   BP,
