Product Description

ASTM182 F316L BLIND SPECTACLE- 2 FLANGE B16.48

ASTM A182 F316L is a standard specification for forged or rolled alloy and Stainless Steel Pipe flanges, forged fittings, and valves for high-temperature service. It covers flanges in sizes NPS 1/2 to NPS 24, fittings in sizes NPS 1/2 to NPS 4, and valves in sizes NPS 1/2 to NPS 4.

A blind spectacle flange is a type of flange that is used to close the end of a pipe or vessel. It is typically used when future expansion or maintenance might be required. The blind spectacle flange has a solid plate with a small opening or window in the center, which allows for visual inspection or access to the interior of the pipe or vessel without fully removing the flange.

B16.48 refers to the ASME/ANSI standard for line blanks, which includes blind flanges. It specifies the dimensions, tolerances, materials, and markings for line blanks, including blind flanges. The standard covers line blanks in sizes NPS 1/2 to NPS 24 and pressure classes 150, 300, 400, 600, 900, 1500, and 2500.

In summary, ASTM A182 F316L blind spectacle flange with B16.48 refers to a blind flange made of stainless steel grade 316L, manufactured according to ASTM A182 standards, and complying with the dimensions and specifications outlined in B16.48.

Spectacle blind flanges are used in various applications where a temporary or permanent isolation of a pipeline is required. Some common applications of spectacle blind flanges include:

1. Maintenance and Repair: Spectacle blind flanges are often used during maintenance and repair activities to isolate a section of the pipeline. This allows technicians to work on the isolated section without interrupting the flow in the rest of the pipeline.

2. Pressure Testing: Spectacle blind flanges are used in pressure testing of pipelines. By installing a spectacle blind flange, one side of the pipeline can be sealed off, allowing pressure to be applied to the other side for testing purposes.

3. Flow Diversion: Spectacle blind flanges can be used to divert the flow of a pipeline to a different direction. By closing off one side of the spectacle blind flange, the flow is directed through the other side of the flange.

4. Emergency Shutdown: In case of an emergency or equipment failure, spectacle blind flanges can be used to quickly isolate a section of the pipeline to prevent further damage or leakage.

5. Changeover of Equipment: Spectacle blind flanges are used during the changeover of equipment or machinery in a pipeline system. By isolating the section with the spectacle blind flange, the equipment can be replaced or repaired without interrupting the flow in the rest of the pipeline.

6. Batch Processing: Spectacle blind flanges are used in batch processing operations where different products or materials need to be processed sequentially. By isolating the sections with spectacle blind flanges, the different batches can be processed without contamination or mixing.
