Stainless Steel Forged PL Flange
Plate welding flanges are a common type of pipe connection components, widely used in industrial piping systems. They have a relatively simple structure, mainly consisting of flange plates and bolt holes for connection. The flange plate is usually circular, with a certain thickness and diameter. Its surface is flat and can be well welded to the pipe to ensure the sealing and stability of the pipe connection.
In terms of materials, plate welding flanges can be manufactured from a variety of metallic materials, such as carbon steel, stainless steel, etc., to meet the requirements of different working environments and media. Carbon steel plate welding flanges have good strength and are cost-effective, suitable for general industrial pipelines, such as those used for transporting media like water, steam, and air. Stainless steel ones have excellent corrosion resistance and are often used in fields with high requirements for the purity of media and the corrosion resistance of pipelines, such as the chemical, food, and pharmaceutical industries. Regarding size specifications, plate welding flanges are available in a variety of standard sizes, and their nominal pressure ratings also vary, capable of meeting the pressure requirements of different piping systems ranging from low pressure to medium pressure.
For example, common nominal pressures include PN0.6MPa, PN1.0MPa, PN1.6MPa, etc. Users can choose the appropriate specifications of plate welding flanges for installation and connection according to the actual working pressure and flow requirements of the pipeline. The connection method of plate welding flanges is simple. After welding the flange to the pipe, two flanges are tightly connected together using bolts and nuts. Usually, a sealing gasket is added in between to prevent media leakage. This connection method not only ensures the firmness of the piping system but also facilitates installation, disassembly, and maintenance. It has important practical value in industrial production and can effectively achieve functions such as branching connections of pipelines, changing the flow direction, and connecting pipes with different diameters. It is an indispensable part of modern industrial piping systems.
