FLANGES
Product Overview
Saakar Solution supplies high-quality stainless steel flanges designed for robust, leak-proof connections in industrial piping systems.
Flanges facilitate easy assembly and disassembly of pipes, valves, and equipment, ideal for high-pressure applications in oil and gas, petrochemicals, power plants, and water treatment. Available in weld neck, slip-on, blind, socket weld, and threaded types across grades like 304, 316L, and duplex, they support sizes from 1/2" to 24" and various pressure classes.
Reducing WN Flange
Weld neck flange (WN flange) has a neck that can relocate stress of the pipe, so to reduce the pressure that gathered in the flange bottom. It is compatible to the pipeline that works in high or low temperature and bear high pressure. Specially for the pipe or the valves when PN is larger than 2.5 Mpa.
Sizes: 1/2” to 4” (NB Nominal Bore)
Material: Stainless Steel (Gr. 304, 316), Monel, Inconel, Hastelloy, Duplex and Super Duplex
LONG WN FLANGE
Weld neck flange (WN flange) has a neck that can relocate stress of the pipe, so to reduce the pressure that gathered in the flange bottom. It is compatible to the pipeline that works in high or low temperature and bear high pressure. Specially for the pipe or the valves when PN is larger than 2.5 Mpa.
Sizes: 1/2” to 4” (NB Nominal Bore)
Material: Stainless Steel (Gr. 304, 316), Monel, Inconel, Hastelloy, Duplex and Super Duplex
SLIP ON FLANGE
Slip on flange, also called SO flange. It’s a kind of flange slides over the pipe with internal design is slightly larger than the pipe. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, the SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange. It is used to insert the pipe into the inner hole of the flange.
Sizes: 1/2” to 4” (NB Nominal Bore)
Material: Stainless Steel (Gr. 304, 316), Monel, Inconel, Hastelloy, Duplex and Super Duplex
Socket Weld Flange
Socket weld flange simplified as SW flange, it has a recessed area (like a shoulder) in the flange bore, this shoulder serves as a guide to set the depth of the pipe that inserted to the flange. Socket welding flange initially designed for high pressure small diameters piping system. Socket weld flange could replace threaded flange, to minimize the risk of leakage. It is recommended for applications where internal welding operations are particularly difficult.
Sizes: 1/2” to 4” (NB Nominal Bore)
Material: Stainless Steel (Gr. 304, 316), Monel, Inconel, Hastelloy, Duplex and Super Duplex
Lap Joint Flange
Lap joint flange (simplified as LTF flange) shape is similar to slip on flange, it has a curved radius at the bore, which can connect with a stub end fittings and slide over the pipe. In this form, the pipe is usually welded to this stub end so the lap joint flange can rotate freely around the stub end. The advantage of this combination is that it will be easy with alignment for the bolt hole, easy to install and uninstall, much more convenient to do examinations and maintenance.
Sizes: 1/2” to 4” (NB Nominal Bore)
Material: Stainless Steel (Gr. 304, 316), Monel, Inconel, Hastelloy, Duplex and Super Duplex
Threaded Flange
Threaded flange is connecting with pipe without welding. It is similar to slip on flange or a socket weld flange, fitted with a tapered thread (screw) inside the flange bore that is mounted on the pipe with corresponding external threads. In some cases a seal weld also applied in conjunction with threaded pipe flange. The threaded flange is screwed to the threaded pipe by the thread, which is processed in the inner hole of the flange. So it does not need to be welded and hence is so convenient for installation and maintenance.
Sizes: 1/2” to 4” (NB Nominal Bore)
Material: Stainless Steel (Gr. 304, 316), Monel, Inconel, Hastelloy, Duplex and Super Duplex
Blind Flange
Blind flange is like a flange cover, also called blind disk or flanged pipe plug. Blind flange has no holes in the center, for to seal the pipe opening. So its function is the same as the pipe plug or the pipe cap. The difference is blind flange is a detachable equipment, easy to replace or to do maintenance.
Sizes: 1/2” to 4” (NB Nominal Bore)
Material: Stainless Steel (Gr. 304, 316), Monel, Inconel, Hastelloy, Duplex & Super Duplex
Spectacle Blind
Spectacle blinds (also known as Spectacle flanges) are manufactured from steel plates and are basically two interconnected discs: one is actually a ring (i.e. a disc with a hole of the same bore size of the pipeline), the other is a solid disc. In normal conditions, spectacle blinds are installed in the open position and do not interrupt the flow of the fluid conveyed by the pipeline.
Sizes: 0-1 inch, 1-5 inch, 5-10 inch, 10-20 inch
Material: Stainless Steel (Gr. 304, 316)
