Do you understand blind flange?
What is a blind panel?
The SS blind plate is mainly used to completely isolate the production medium to prevent the lax closing of the shut-off valve from affecting production or even causing accidents. The stainless steel blind plate should be installed in the parts that require isolation, such as the equipment connection port, the front and rear of the shut-off valve, or between two flanges. It is often recommended to use an 8-shaped blind plate; inserts can also be used for one-time use parts such as pressing and purging. Plate (round blind plate).
The function and classification of blind plates
From the appearance point of view, blind plates are generally divided into flat plate blind plates, figure 8 blind plates, insert plates, and gasket rings (the insert plates and gasket rings are blind to each other). The blind plate plays the role of isolation and cutting, which is the same as the function of the head, pipe cap and welding plug. Due to its good sealing performance, it is generally used as a reliable isolation method for systems that require complete isolation. The plate blind plate is a solid circle with a handle, which is used for systems that are normally isolated. The figure 8 blind plate is shaped like a figure 8. One end is a blind plate and the other end is a throttling ring, but the diameter is the same as the diameter of the pipe and does not play a throttling role. The figure 8 blind plate is easy to use. When isolation is required, use the blind plate end. When normal operation is required, use the throttle ring end. It can also be used to fill the installation gap of the blind plate on the pipeline. Another feature is that the signs are clearly visible, making it easy to identify the installation status.
Production Process of stainless blind plate
Generally divided into four types: forging, casting and forging, medium plate cutting, and casting. Among them, forged products have the highest price, followed by medium plates, and cast and forged products have the lowest price. Casting is the last craft. The quality is better for forged and medium plates, but slightly worse for cast and forged ones.
