Astm A182 304 / 304L 316 / 316L stainless steel blind flange (BL)flanges ASME B16.5

"zheheng steel" is a professional manufacturer of stainless steel stainless steel flanges and various special flanges. The company is also good at the production of mechanical parts of various materials.

blind flange is also called blind plate, and its proper name is flange cover. It is a flange without holes in the middle

for sealing the pipe plug. Ansi asme b16.5 a105 flange have many types of sealing surface, such as plane, convex

, concave and convex, tenon and groove surface, and ring connection surface.

what is blind flange
The formal name of blind flange (blind disk) is Flange cover, and some are also called blind flange or pipe plug. It is a flange without a hole in the middle, which is used to block the pipe mouth. The function is the same as the head and tube cap, except that the blind plate seal is a detachable sealing device, and the head seal is not ready to be opened again.

The parts that connect the pipe to the pipe are connected to the pipe end. There are holes in the flange, and the bolts tightly connect the two flanges. The flanges are sealed with gaskets. Flange is a disc-shaped part, the most common in pipeline engineering, flanges are used in pairs.

Flange is divided into threaded connection (screw connection) flange, welding flange and clip flange. Flanges are used in pairs, low-pressure pipes can use wire flanges, welding flanges for pressures above 4 kg. Add a gasket between the two flanges, and then tighten with bolts.

Flange application:
Because the flange has good comprehensive performance, it is widely used in chemical engineering, construction, water supply, drainage, petroleum, light and heavy industry, freezing, sanitation, plumbing, firefighting, power, aerospace, shipbuilding and other basic projects.

Application of blind flange:

During the initial start-up preparation phase, when the strength test or tightness test of the pipeline cannot be performed simultaneously with the connected equipment (such as turbine, compressor, gasifier, reactor, etc.), the equipment and pipeline Set a blind plate at the connection.

Various process material pipes connected to the boundary area outside the boundary area, when the device is stopped, if the pipeline is still in operation, set a blind plate at the cut-off valve.
