    Material:Stainless Steel SUS304

    SUS304 material is a Japanese JIS standard and the most commonly used stainless steel, containing 18% Cr and 8% Ni. It can maintain good strength and heat resistance in high temperature and low temperature environments, and also has good corrosion resistance, weldability, cold workability and mechanical properties in the mild atmosphere.

    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.
