Product Description

A “BL” type flange typically refers to a blind flange, which is a solid disk used to block off a pipeline or to create a dead end. Here’s a product description for a BL type flange:

Standard Compliance: The flange conforms to specific standards such as ANSI B16.5, ANSI B16.47, ISO 7005, etc.

Size: Available in various sizes ranging from small to large, typically denoted in nominal pipe sizes (NPS) or in millimeters, indicating the diameter of the pipe it fits.

Pressure Rating: Designed to withstand certain pressures safely, specified in pounds per square inch (psi) or in bar.

Material: Constructed from materials suitable for the intended application, commonly carbon steel, stainless steel, alloy steel, or other alloys depending on corrosion resistance and mechanical properties required.

Facing: The facing of the flange, indicating the surface finish where it seals against the mating flange. Options include raised face (RF), flat face (FF), and ring-type joint (RTJ).

Connection Type: Blind flanges do not have a bore and are typically bolted to the mating flange using bolts and nuts. The connection method may vary depending on the standard and application.

Application: Used to close the end of a pipeline or vessel, or in situations where temporary or permanent closure of a piping system is required. They are commonly used in pressure testing and maintenance procedures.

Additional Features: May include special coatings for corrosion resistance, additional testing or certification requirements, or any other features tailored to specific applications or customer needs.
