The role of Stainless Steel Flange is to add a sealing point between the two flange blind plates and then tighten them with bolts. Blind flanges of different pressures have different thicknesses and use different bolts. When water pumps and valves are connected to pipelines, parts of these equipment are also made into corresponding flange shapes, also known as flange connections. All connecting parts that are bolted and closed at the same time on two planes. Blind flanges can show good effects and values ​​in certain fields and industries. Flange covers can fully play a certain role. Large flange covers need to continuously produce certain functions and values. They have certain performance and advantages in pipeline connections and play an important role and trend.

Role of flange covers

The formal name of the blind plate 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 the pipe opening. The function 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 ready to be opened again.

There are many types of sealing surfaces. The national standard flange cover has flat surface, convex surface, concave and convex surface, tongue and groove surface and ring connection surface. The materials include carbon steel, stainless steel, alloy steel, copper, aluminum, PVC and PPR, etc.

From the appearance, the blind plate is generally divided into plate-type flat blind plate, 8-shaped blind plate, plug plate, and gasket (plug plate and gasket are blindly connected to each other).

Generally divided into four types: forging, casting, medium plate cutting, and casting. Among them, the price of forged products is slightly higher, followed by medium plate, and casting is slightly lower. Casting is the first process.
