Spectacle Blind Flange and ASME 16.48 Spacer Blank manufacturer India

ASME 16.48 Spacer Blank Flange and Stainless Steel Spectacle Blinds manufacturer in India

The Spectacle Blind can be described as a steel plate cut into discs of a given thickness. The two disks are connected by a section that looks like a nose piece of your regular glasses. While one disk of the Spectacle Blind Flange is solid, the other is hollow like a ring. The inside diameter of the spectacle blinds is the same as that of the flange. As one of the most experienced spectacle blind flange manufacturers, we can state that these are used in systems that must be separated from other installations regularly. The A105 Spectacle Blind flange is mostly mounted in the ‘open’ position for easy flow through the pipe. Once the flange is rotated to a ‘closed position, the flow will completely stop.

One of the main reasons for using ASME 16.48 Spacer Blank Flanges is because they can easily control the flow in pipes. This helps in easy maintenance of the pipes. We manufacture Carbon Steel Spectacle Blind Flange of various international standards. Clients can let us know about their specific requirements, and we will customize the Alloy steel Spacer Blank Flange accordingly. We use various high-quality raw materials in the API 590 spectacle blind manufacturing process like stainless steel, copper, etc. Thus clients can always be assured about the quality of our products. Our Stainless Steel Spectacle Blind Flange goes through several quality checks with third parties and us too, and they are sent for delivery only after getting the desired certifications.

Apart from the ANSI 16.48 spectacle blind rf, we also manufacture the Spade Blind Flange, which comes with a handle plate and has the same usage as a spectacle blind flange’s blind part. It is also known as the Paddle Blind Flange. To reduce the weight of flange connections, we might choose to keep the two parts of the API 590 spectacle blind flange separately.

If you are looking for good quality SS spade blind flange at affordable prices, contact us directly. We have happy customers based in different parts of the world who have been using our Slip Blind flanges for many years. We use the best technologies for manufacturing the Spectacle Blank; hence they are always dimensionally accurate. We also offer fast and doorstep delivery of our Slip Blind Flange for the convenience of our esteemed clients.
