法兰盘

A flange plate is a flat, circular component used to connect pipes, valves, pumps, and other equipment in mechanical systems, providing a secure, sealed joint.

技术定义与适配语境
典型 法兰盘 会按材料、尺寸公差、适配关系和失效风险在 机械和设备制造 中评估。

A flange plate is a critical mechanical component designed to facilitate the connection of two sections of piping or equipment. It typically features a flat, circular shape with a central bore and a series of bolt holes arranged around its perimeter. The primary function is to create a strong, pressure-resistant, and leak-proof joint when bolted to a mating flange, often with a gasket inserted between them. It is integral to flange assemblies in various industrial systems, enabling assembly, disassembly, and maintenance.

定义
A flange plate is a critical mechanical component designed to facilitate the connection of two sections of piping or equipment. It typically features a flat, circular shape with a central bore and a series of bolt holes arranged around its perimeter. The primary function is to create a strong, pressure-resistant, and leak-proof joint when bolted to a mating flange, often with a gasket inserted between them. It is integral to flange assemblies in various industrial systems, enabling assembly, disassembly, and maintenance.
工作原理
The flange plate works by providing a mating surface that, when aligned with another flange and compressed together with bolts, creates a sealed connection. The applied bolt torque generates clamping force, which compresses a gasket between the flanges to form a tight seal, preventing fluid or gas leakage while withstanding internal pressure and mechanical loads.
材料
Common materials include carbon steel (e.g.ASTM A105)stainless steel (e.g.ASTM A182 F304/F316)alloy steeland sometimes ductile iron or aluminumselected based on pressuretemperaturecorrosion resistanceand application requirements.
