A weld neck raised face flange also known as high hub flange it is a type of flange which is used regularly with other pipes. These WNRF Flanges consist of circular fittings with a protruding rim around the circumference. These flanges are typically butt welded to a pipe which is especially helpful for being suitable for the use in hostile environments that have extremes of various temperature and pressure along with other sources of stress. It can easily take pressure of 5,000 PSI. We at Pipe Fittings Suppliers successfully manufacture and supply these products with types of materials like Stainless steel, SS Weld Neck Raised Face, Alloy Steel Raised Face, nickel alloys welded raised face and also other as required. The size which includes are from (15 NB) to 48" (1200NB), With classifications of 150 LBS, 300 LBS, 600 LBS, 900 LBS, 1500 LBS, 2500 LBS, DIN Standard ND-6,10, 16, 25 and 40. Each has their own standards like ANSI B16.5, ANSI B16.47, MSS SP44, ANSI B16.36, and ANSI B16.48.
