SA516 Gr. 60/70 Spectacle Blind Flanges require no welding for installation. Typically, spectacle blinds are use to join together or permanently divide pipe networks. A steel plate with 2 discs of a specific thickness is known as a spectacle blind flange. A steel element that resembles the nosepiece of a pair of glasses holds the two discs together.
Pumps, valves, pipes, and other components can connect with the use of flanges to create a pipeline system. Flanges are often connect using threaded screws or welding.
SA516 Gr. 60/70 Spectacle Blind Flanges make it possible for simple pipe system maintenance and repair.
What is a spectacle blind flange?
Simple safety tools called spectacle blinds are mount in between two pipe flanges. The open end is insert as a spacer during normal operation to ensure uninterrupt flow. SA516 Gr.60-70 spectacle blind end is rotated into position between the flanges to stop the flow in the pipeline.
How do you install spectacle blind flange?
Between two horizontal pipe runs, spectacle blinds are install. Installing the blind involves passing one of the flange bolts through the hole on the central tie bar rather than securing it with bolts around the entire diameter of the pipe like you would with a pipe flange.
How many types of blind flanges are there?
The varieties of blind flanges are numerous. The flat face (FF) and raised face (RF) blind flanges are the two most used varieties. A flat face flange has a surface that is entirely level and smooth. There are two levels on the surface of the raised face flange due to the central portion’s minor elevation.
What is a slip-on flange?
A slip-on flange is essentially a ring that is put over the pipe and has enough space between it and the pipe end for a weld to be apply to the inside diameter. On the back of the flange, the OD of the slip-on flange is likewise welded.
