SUS304 5K BL-FF JIS Standard Stainless Steel Flange
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-BLFF Blind Flat 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 Flat Face flange has a gasket surface in the same plane as the bolting circle face. Applications using flat face flanges are frequently those in which the mating flange or flanged fitting is made from a casting.
