ASME B16.5 Flanges

Refer ASA B16 5 Pipe Flanges Dimensions Metric/ Schedule Char And ANSI B16.5 Industrial Flange Manufacturer In India.


A flange can be defined as a pipe connection method that helps form a full-fledged piping system. Advantages of using a flange like that of ASME B16.5 Flange include easy cleaning access, along with quick inspections and required modifications. Clients can get customized ASA B16 5 Pipe Flanges from us, which are either welded or screwed. We Manufacturer ANSI B16.5 Industrial flange, which is commonly used in different industries like chemical, petroleum, etc., and bolted/welded together to allow easy transportation and operations of the whole piping system. We are one of the top Pipe Flanges Manufacturers In India who focuses on creating high-quality products at the most reasonable prices.

We produce different Flanges Used In Oil And Gas Industry like weld neck flanges, slip-on flanges, blind flanges, socket weld flanges, lap joint flanges, threaded flanges, etc. Our customized ASME B16.5 Forged Flanges are made up of stainless steel and last for many years. They are available in sizes NPS ½ to 12 and are made according to standards

The ASME B16.5 Flanges Dimensions varies and each flanges comes with different standard dimensions- these are the best for smooth operations and maintenance. With flanges, inspecting faults in a small section of the pipe becomes easier.
