Pipe plate flange, also known as non perforated flange, is a key component used to close pipeline openings. Its function is similar to that of head and pipe cap, but it has the characteristic of detachable sealing. Here is a detailed introduction about it:

Structure type:

Fixed tube plate: This is a common type where the tube plate is fixed to the shell by welding, and the position of the tube bundle remains unchanged. It is suitable for most medium and low pressure application scenarios.

U-shaped tube type: Using U-shaped tubes as the bundle, one end is fixed on the tube plate, and the other end can move freely, which can adapt to thermal expansion and contraction and is suitable for high temperature and high pressure environments.

Floating tube plate: The tube plate is not directly connected to the shell, but maintains a certain gap between the floating tube plate and the shell, allowing the tube plate to move freely during thermal expansion and reducing thermal stress.

K-type tube plate: It is a derivative form of U-shaped tube design, and the tube bundle is composed of K-type tubes. The ends of the tubes are located on both sides of the tube plate, expanding the heat exchange area.

Double tube plate: equipped with two tube plates connected to each other through a bundle, usually used for applications that require complete isolation of two fluids.

Working Principle:

Connection mechanism: By tightening bolts, two flanges are tightly connected to achieve the connection between pipelines or equipment. The pre tightening effect of the bolts ensures a tight fit between the flanges, forming an effective sealing structure.

Sealing function: Insert gaskets between flanges to achieve a sealing effect. The gasket material can be metal, non-metal, or composite material, and should be selected according to the working environment and medium characteristics. When the bolt is preloaded, the gasket is compressed, thereby achieving sealing.

Pressure bearing: The flange of the pipe plate has the ability to withstand a certain amount of pressure, ensuring that the pipeline or equipment does not leak during operation. The thickness of the flange and the size, quantity, and layout of the bolts have a significant impact on its pressure bearing capacity.

Power transmission: It plays a role in transmitting force in pipeline systems, such as transmitting the thrust, tension, etc. of pipelines to equipment or pipelines, ensuring the stable operation of the system.

Product Features:

High strength: During the forging process, the metal undergoes plastic deformation to refine the grain size, enhancing the mechanical properties and structural strength of the material.

High precision: Forging technology can produce components with high dimensional accuracy, reducing the workload of subsequent processing.

Excellent performance: It has outstanding mechanical properties, including tensile strength, toughness, and fatigue strength.

Customization flexibility: Able to flexibly customize the shape, size, and performance of tube plate forgings according to specific application needs.

Good durability: Thanks to its high quality and excellent mechanical properties, forged parts often have a longer service life.

Application areas: Tube plate flanges are widely used in industries such as pharmaceuticals, food production, petroleum, papermaking, and natural gas due to their advantages of simple structure, excellent sealing, and strong adaptability.
