Pipe Flanges are an integral part of piping used to join two consecutive pipes or rather block to end the pipeline. A pipe flange is either a ring type, collar or a circular blank disc either welded or screwed to the pipe. Flanges are used in pairs connected by bolted joint and provides strength to the pipeline. A flanged joint is second most used method of joining after welding and is versatile in terms of maintenance
Ferrobend is a manufacturer of pipe flanges with full range of sizes, types and material. We also supply complete flange set with companions such as gaskets, stud bolts, bolt sleeve, spectacle blind, spade, spacer and orifice plate. Weld neck, slip-on, socket weld, threaded, lap joint, blind are 6 basic types of pipe flanges offered by Ferrobend. We also produce long weld neck and large diameter flanges
Pipe flange with a high hub often called as a neck that is used to weld the pipe. This pattern transfers the stress on to the pipe thus handling high pressure service.
Ring type pipe flange which slips over the pipe and welded. The inside diameter of the pipe is slightly large than the pipe's outer diameter.
Ring type pipe flange with recessed groove which acts as a socket and holds the plain end of the pipe. Typically used for smaller diameter and high pressure lines.
Pipe flange similar to slip on flange but with female tapered threads at the bore to suit incoming pipe threads. Threaded flange is used for small diameter high pressure lines
Lap joint flange are exactly similar to slip on flange but with radius cut over the bore to occupy and facilitate free revolution of the stub end fitting
A pipe flange as circular plate with all relevant bolt holes but no center bore, paired with any other type of pipe flange to block or terminate the pipeline.
A long weld neck flange is an upgraded version of a weld neck flange with extended hub OR neck for welding a pipe, typically used for high pressure lines.
Flanges for connecting large diameter pipes or pipe fitting covering sizes above 24 upto 100 inch. Large diameter flanges are intended for low pressure service.
