China OEM Stainless Steel Threaded Flange Manufacturers – Blind Flanges – DS PIPE Detail:

Description

Blind flanges are solid steel pieces with no holes (inside diameter) designed primarily for capping pipelines. Since most flanged connections allow air or fluid to pass through an internal opening, louvers provide a well-formed termination point for the end of a pipe connection or to reroute the associated medium to another part of the pipe assembly. Blind flanges are selected in these cases, and when the pipeline requires future modifications (such as installing valves or fittings to reroute flow).

The majority of blind flanges are of basic constitution, require minimal machining compared to other flanges, and weigh more than most options given the lack of a bore. Although these are typically provided as blanks to match up to slip on and weld neck flanges, we offer them custom machined as well. Popular alterations include NPT threads in the center, as well as custom bore holes to function as slip on flanges without hubs.

Spectacle Blinds are another somewhat uncommon but important application for capping pipelines. A picture of a spectacle blind is shown below. The name comes from the fact that the assembly looks like eyeglasses, or “spectacles”. These are normally used in piping systems, usually between two standard flanges, and are designed to block off a section of pipe. However these are used where the customer needs to block this connection off somewhat frequently. They are typically used where there is piping connected to both flanges, where you cannot simply drop a standard blind flange in, because the flanges cannot be pulled apart far enough to drop in the blind flange.
