Flange connection is a kind of detachable connection, which can be connected according to different parts to ensure the normal connection of the flange. Flanges have different classification criteria and classification, according to the connected components can be divided into the container flange and pipe flange. Divided by the structure type, there is a whole flange, flange and threaded flange flange. Large flange common flange with flat welding flange and butt flange. Welded flat flange less rigid, suitable for pressure p ≤ 4MPa occasions; also known as flange welded flange, more rigid, suitable for high pressure and temperature applications. There are three types of flange sealing surface: flat sealing surface, suitable for low pressure, medium non-toxic occasions; concave and convex sealing surface, suitable for slightly higher pressure occasions; tongue and groove sealing surface, suitable for flammable and explosive , Toxic media and high pressure occasions. Different types of flanged pipe fittings have good product performance in different fields. The adaptability of different occasions and spaces will produce different effects. Ordinary rubber gasket for temperatures below 120 ℃ occasions; asbestos rubber gasket for water vapor temperature of less than 450 ℃, the oil temperature is less than 350 ℃, the pressure is less than 5MPa occasions, the general corrosion Medium, the most commonly used acid asbestos board. Large flanges are made of high-pressure equipment and piping, made of copper, aluminum, No. 10 steel, stainless steel lens or other shapes of metal gasket. Large flange high-pressure gaskets and sealing surface contact width is very narrow (line contact), sealing surface and gasket processing finish higher. Large flange gasket is a can produce plastic deformation, and with a certain strength of the material made of the ring. Most of the gaskets are cut from non-metal plates, or made by the professional factory according to the required size. The materials are asbestos rubber plates, asbestos plates, polyethylene plates, etc .; also thin asbestos (white metal, stainless steel) And other non-metallic materials wrapped up made of metal pads; there is a thin strip of steel and asbestos with winding wound gasket. Large flanges will have different value in use, have different effects and uses. Large flange of different materials, production and processing technology will be different, so in the use and processing of large flanges to pay attention to the method, in accordance with certain procedures and methods for use.

Hydraulic Support System Seals Kits
The hydraulic support system used in mines is used to support equipment during the mining process of coal mines or other underground mines.
It mainly consists of hydraulic supports, hydraulic stations, control systems, and sensors.
Hydraulic support is the core component of the hydraulic support system used in mines, which uses hydraulic cylinders as the support force source,
Capable of supporting huge rock weights in underground mines. The hydraulic station provides a hydraulic oil source,
Hydraulic oil is transported to the hydraulic support through pipelines to achieve support function.
The control system is an important component of the hydraulic support system used in mines, which controls and monitors the hydraulic support through sensors and controllers. Sensors can monitor the status of the bracket in real-time, including support force
The controller controls the hydraulic support based on the feedback data from sensors, such as inclination and displacement, to ensure its stability and safety in the mine.
The hydraulic support system used in mines has advantages such as high support force, good stability, and safety and reliability,
Widely used in underground mining industries such as coal mines, metal mines, and non-metallic mines. With the continuous progress of technology and the continuous expansion of applications, hydraulic support systems for mines will continue to play an important role,
Provide strong support for the safe and efficient development of the underground mining industry.
