Blind plates are generally divided into four types: forging, casting and forging, medium plate cutting, and casting. Among them, the price of forged products is the highest, followed by medium plate, and casting and forging is the lowest. Casting is the last process. The quality is better for forged and medium plates,...
The blind plate should be set at the part that requires isolation (cut-off), such as at the port of the equipment, before and after the shut-off valve or between two flanges. It is usually recommended to use a figure 8 blind plate; a plug-in plate (round blind plate) can also be used for one-time use parts such as...
The blind plate is commonly known as the blind plate. The material of the blind plate is carbon steel, stainless steel, alloy steel, copper, aluminum, etc. The sealing surface is flat, convex, and concave-convex. The blind plate is used for isolation and cutting. And head, pipe cap, welding plug
Our forging factory is a manufacturer of pressure vessel forgings, blind flange forgings, and forgings of various materials. The formal name of the blind plate is flange cover; some are also called blind flanges. It is a flange without a hole in the middle and is used to seal the pipe opening. The function is the same...
The blind plate is mainly used to completely isolate the production medium to prevent production from being affected or even accidents caused by the shut-off valve being lax. The blind plate should be installed in the part that requires isolation, such as the equipment connection port, the front and rear of the...
The role of the blind plate is to isolate and cut off. It is connected to the flange of the same specification with bolts, and a sealing gasket is sandwiched between the two, which can seal one end of the pipe and block it to form a blind end, so it is called blind plate.
From the appearance point of view, the blind plate is generally divided into plate-type flat blind plate, 8-shaped blind plate, insert plate, and backing ring (the insert plate and the backing ring are mutually blind).

China Blind Flange Suppliers
Blind Flanges are manufactured without a bore and used to blank off the ends of piping, Valves and pressure vessel openings.
From the standpoint of internal pressure and bolt loading, blind flanges, particularly in the larger sizes, are the most highly stressed flange types.
However, most of these stresses are bending types near the center, and since there is no standard inside diameter, these flanges are suitable for higher pressure temperature applications.
