Features of ANSI/ASME Class 150 Blind Flanges:

Blind flanges, also known as blanking flanges, are solid disks used to block off a pipeline or to create a stop. They are commonly used for pressure testing the flow of liquid or gas through a pipe or vessel. Here are some key characteristics and applications of blind flanges:

Design: Blind flanges are typically round plates with bolt holes around the perimeter for easy installation and removal. The bolt holes allow the flange to be securely attached to the mating flange or nozzle using bolts.

Sealing: Blind flanges are designed to provide a seal at the end of a piping system. They effectively block the flow of fluid or gas and prevent leakage from the open end of the pipe.

Pressure Testing: Blind flanges are often used during hydrostatic or pneumatic pressure testing of pipelines and vessels. By installing a blind flange at the end of the pipe, pressure can be safely applied to test the integrity of the system.

Maintenance and Inspection: During maintenance or inspection of a piping system, blind flanges can be used to seal off sections of the pipeline, allowing work to be carried out on specific segments without interrupting the overall flow.

Customization: Blind flanges can be manufactured in various sizes, pressure ratings, and materials to suit specific application requirements. They are available in different standards such as ASME/ANSI, API, DIN, and others.

Material Options: Blind flanges are made from a variety of materials including carbon steel, stainless steel, alloy steel, and other alloys, depending on the application and the properties required for the specific operating conditions.
