Stainless steel flange (Flange) is also called flange or flange Flanges are the parts that connect pipes to each other and connect them to the pipe ends Stainless steel flange has eyelet bolts to connect the two flanges tightly Seal between flanges with gasket Flanges are divided into threaded (wire) flanges and welded flanges

Stainless steel flange is a kind of disk-shaped part. The most common flanges in pipeline engineering are used in pairs and with matching flanges on valves In pipeline engineering, flanges are mainly used for pipeline connection Install a flange in all kinds of pipes to be connected. Low-pressure pipes can use wire flanges. Welded flanges with pressure above 4 kg can be used Add a gasket between the two flanges and fasten them with bolts Flanges with different pressures have different thicknesses and use different bolts When pumps and valves are connected with pipes, the parts of these equipment are also made into corresponding flange shapes, also known as flange connections Connecting parts that are bolted at the periphery of two planes and closed at the same time are generally called "flanges". Such as the connection of ventilation pipes, this kind of parts can be called "flange parts" But this kind of connection is only a part of the equipment, such as the connection between flange and water pump, which is not good. The water pump is called "flange parts" Smaller ones such as valves can be called "flange parts" A gasket is a ring made of a material that can produce plastic deformation and has a certain strength Most gaskets are cut from non-metallic plates or made by professional factories according to the prescribed dimensions. Their materials are asbestos rubber plate asbestos plate polyethylene plate and so on; Also useful thin metal plate (tin stainless steel) will asbestos and other non-metallic materials wrapped up made of metal wrap gaskets; There is also a winding gasket made of thin steel strip and asbestos strip Ordinary rubber gasket is suitable for occasions where the temperature is lower than 120 ℃; Asbestos rubber gasket suitable for water vapor temperature below 450 ℃, oil temperature below 350 ℃ and pressure below 5MPa. For general corrosive medium, the most commonly used is acid-resistant asbestos board Lens-shaped or other metal gaskets made of copper, aluminum, No.10 steel and stainless steel in high-pressure equipment and pipelines The contact width between high pressure gasket and sealing surface is very narrow (line contact), and the machining finish of sealing surface and gasket is high Low-pressure small-diameter wired flange high-pressure and low-pressure large-diameter are welded flanges the thickness of flange and the diameter and number of connecting bolts are different under different pressures
