ANSI B16.5 Lap Joint Flanges
Stainless steel Lap Joint Flanges
Carbon steel Lap Joint Flanges
Dinesh Industries is Lap Joint Flange (LJ Flanges) Manufacturer in India manufacture Class 150 to Class 2500 LJ Flange, type of sealing face RF, FF & RTJ, material in kinds of carbon steel, low temperature carbon steel, alloy steel, stainless steel, Inconel & Hastelloy.LJ Flange is used with stud ends, according to ANSI B16.5/ANSI B16.47 Series A/ANSI B16.47 Series B American Standard. We also manufacture as per DIN Standard, BS Standard, JIS Standard, GOST Standards depends upon our customers requirements & Drawings.
Lap Joint Flanges are similar to other types of industrial flanges, but it does not have a raised face. Lap joint flanges are used in conjunction with a “Lap Joint Stub End”. The total initial cost of a lap joint flange along with a stub end is around one-third higher than that of comparable welding neck flanges. The pressure holding capacity of lap joint flanges is comparatively lower, and the fatigue life for the assembly is only one tenth that of welding neck flanges.
