SUS304 10K BL-RF JIS Standard Stainless Steel Blind Raised Face Flange

Product Information

A stainless steel blind raised face flange is a type of flange made from stainless steel that features a raised face design on the sealing surface.Stainless steel blind raised face flanges are typically made from stainless steel grades such as 304, 316, 316L, or other suitable stainless steel alloys. Stainless steel offers excellent corrosion resistance, durability, and strength, making it suitable for a wide range of applications.The blind flange has a raised face on the sealing surface. The raised face provides a flat surface for better contact with the gasket, facilitating a secure and leak-free seal when the flange is bolted to another flange or equipment.

The blind flange is a solid disc-shaped flange with no center opening. It is used to close the end of a piping system or vessel to prevent flow and provide a seal. The blind flange can also be used to create a maintenance access point in the system.

Face Type:BLRF - Blind Raised Face

A blind flange is a circular plate with a bolt hole and a solid surface that is used to seal off a pipeline or to create the end flow. They are widely utilized in the petrochemical, public services, pipe engineering, and water works industries. The blind flange is placed between two open flanges to prevent liquid flow via a pipeline.


Blind flange is typically essential when undertaking pipeline maintenance or repairs as the flow in the pipeline must be stopped for maintenance, yet the nearest valve may be kilometers away from the repair site. As a result, installing a blind flange on a pipeline is far more cost-effective.


The Raised Face flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face. This face type allows the use of a wide combination of gasket designs, including flat ring sheet types and metallic composites such as spiral wound and double jacketed types. The purpose of a RF flange is to concentrate more pressure on a smaller gasket area and thereby increase the pressure containment capability of the joint.
