Product Description


Stainless Steel Blind Flange BLRF, BLFFBL type is used to seal off a section of pipe or a nozzle on a vessel that is not in use. Unlike other flanges that are used to connect pipes, a blind flange is flat and does not have a bore or hole in the center. This design effectively blocks off the flow of fluid through a pipeline, allowing for maintenance, inspection, or system modifications.Stainless Steel Forged Flanges ANSI, BS, JIS, EN, DIN StandardFlanges are external rims, edges, ribs, or collars that connect pipes, valves, pumps, and other equipment to form a piping system. They are typically circular and come with holes that allow them to be bolted together. Flanges are often used to facilitate easy assembly and disassembly of piping systems, and they can also be used for inspection, modification, or cleaning purposes.OTHER FLANGE TYPES

PLATE FLANGE(PL)This type is a flat, circular disk that is welded onto the end of a pipe and connects to another flange or fitting. Unlike more complex flanges, it doesn't have a raised face or a lip for a gasket. Plate flanges are generally used in less demanding applications where ease of assembly and cost are more important than high pressure and temperature resistance.SLIP-ON FLANGES(SO)SO type are designed to slide over the end of a pipe and are then welded in place. They are easier and more economical to install compared to more robust types like weld neck flanges. Typically used in lower-pressure applications, slip-on flanges are popular in industries like water treatment and petrochemicals. They offer a convenient but less durable alternative for connecting pipes in a system. WELD NECK FLANGES(WN)WN type is a type of flange that is designed to be joined to a piping system by butt welding. Unlike other flanges that can be attached to the pipe in various ways, a weld neck flange has a long tapered hub that goes over the end of the pipe. This tapered hub provides an ideal welding area and offers a tight, high-integrity seal that prevents leaks and ensures durability under high stress.
SOCKET WELD FLANGES(SW)SW type are used in applications requiring a strong but easily disassemblable connection. These flanges feature a socket into which the pipe is inserted and then fillet-welded to secure it in place. The design allows for a smooth bore and better fluid or gas flow inside the piping system. Socket weld flanges are often used in small-diameter, high-pressure applications such as hydraulic and steam lines.LOOSE FLANGE(LAP JOINT FLANGE)A Loose Flange, also known as a Lap Joint Flange, consists of a stub end welded to the pipe and a backing flange that slides over it. This design allows for easy maintenance and is often used in low-pressure applications where bolt-hole alignment or frequent system access is required. The flanges can be made from materials like carbon steel or stainless steel, depending on the application.

1. exchange or refund is acceptable. It mainly depends on how you need to deal with it.

FOR FLANGE FACES
FLAT FACE: A flat surface without elevation is used mainly for low-pressure and non-critical applications.RAISED FACE: Features a raised area around the bore, common in many high-pressure applications and allows for a variety of gasket types.
RING-TYPE JOINT (RTJ): Features a grooved face that holds a metal ring gasket, used in high-pressure and high-temperature applications.
LAP JOINT: Often used with a matching stub end, this face allows for easy alignment and is used primarily in systems that require frequent maintenance.
TONGUE AND GROOVE: One flange has a raised ring (tongue), and the other has a depressed ring (groove); they fit into each other to form a tight seal.
MALE AND FEMALE: Similar to tongue and groove but more exaggerated; the male flange has an additional lip, and the female flange has a corresponding recess.
