WN flange is not just another style of flange and is intended to be a superior, more professional fitting. It is machined with precision to exact specifications. It will be as tight as it can get, but at the same time that tightness should not require any adjustment. If you have ever bought a quality flange from a WN flange manufacturer, there is no doubt in your mind that it was the best WN flange you had ever owned or used and that it was a superior flange to that before.

WN flange can be used on pipelines that transport expensive, flammable and explosive media.A standard unit is used to transport flammable and explosive media. A pressure tested unit is required for pipeline inspections. All pipeline systems are considered to be susceptible to damage or fires if they were exposed to extreme pressures that would cause a breakage or rupture of the pipes or fittings carrying the media. Flammable media may spontaneously combust if the temperature exceeds 120° F and the pressure drops below 6,000 psi.Exposure to extreme temperatures may expose a pipeline to the potential for breakages, leakage or other damaging fires.The WN flange design will prevent a leakage of flammable and explosive media such as fuel oil and lubricants. WN flange is widely used in petrochemical, urban water supply and power systems.
