Blind plate
Product Introduction
The formal name for blind flanges is flange cover, and some are also called blind flanges or pipe plugs. It is a flange without a hole in the middle, used to seal pipeline openings. The function of the blind plate seal is the same as that of the head and pipe cap, except that the blind plate seal is a detachable sealing device, and the seal of the head is not intended to be opened again. There are various forms of sealing surfaces, including flat, convex, concave convex, mortise and tenon surfaces, and ring connection surfaces. The materials include carbon steel, stainless steel, alloy steel, copper, aluminum, PVC, and PPR.
From the appearance, blind plates are generally divided into flat plate blind plates, 8-shaped blind plates, insert plates, and gasket rings (insert plates and gasket rings are blind to each other). Blind plates serve the same function as heads, pipe caps, and welding plugs in terms of isolation and cutting. Due to its good sealing performance, it is generally used as a reliable isolation method for systems that require complete isolation. A flat blind plate is a solid circle with a handle, used for systems that are typically in an isolated state.
Premium Flanges For The Oil And Gas Industry
Looking for world-class flanges for your industry? We at Huaxi Flange offer premium flanges with unmatched strength and top-notch performance.
Slip-On Flanges
Slip-on flanges on the pipe and connect without utilizing additional tools for installation. The design of slip-on flanges allows direct and secure pipe connections that can withstand high pressure and temperature conditions without leaking or bursting.
Weld Neck Flanges
A weld neck flanges transfers stress to the pipes, lessening the high-stress concentration at the bottom of the flange. This attribute of weld neck flanges makes them suitable for the oil and gas industry.
Blind Flanges
Blind flanges temporarily or permanently block the flow of fluids or gases in a pipeline. It is beneficial when a pipeline needs to be disconnected from the rest of the system for maintenance, repairs, or other purposes.
Lap Joint Flanges
Lap joint flanges are appropriate for connecting pipes or equipment or fittings together. These flanges are quite similar to slip-on flanges. They are designed to slide over the pipe and create a secure pipe connection using bolts and a stub-end fitting. They are not welded to the pipe and can spin to match bolt holes that are not predetermined. You will see these parts in shipyards often.
Threaded Flanges
A threaded flanges connects a device securely to a pipe without welding. Threads create a secure and leakage-free connection between the flange and the pipe. Threaded flanges work well for fixing equipment quickly.
Socket-Weld Flanges
Socket-weld flanges are suitable for smaller-diameter pipes and operate in lower-pressure/temperature systems. Insert the pipe into the female socket of socket-weld flanges, and then a fillet weld is used around the top to create a connection. It allows a seamless flow of liquid or gas in the pipe.
Other Industries We Serve
Explore diverse industries where flanges truly shine – Huaxi Flange offers solutions for all.
Petrochemical Treatment And Processing
In chemical processing plants, flanges connect pipes and other equipment, ensuring the smooth flow of hazardous chemicals and petroleum products without any leakage.
Power Generation
Flanges join steam and water pipes, assuring a secure transport of fluids in boilers, turbines, and condensers in power plants.
Industrial Pumps And Manufacturing Systems
Flanges are vital in this industry, ensuring the secure connection of pipes and pumps without any leakage in the manufacturing sector.
Food And Beverage Processing
Flanges join pipes in manufacturing and processing lines in the food and beverage industry, ensuring the hygienic and effective movement of liquids and gases.
Large-Scale Pipe Systems And Waterworks
