法兰和垫片

Flanges and gaskets are critical sealing components in industrial piping systems that connect pipe sections while preventing leaks.

技术定义与适配语境
典型 法兰和垫片 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。

Flanges are protruding rims, edges, or collars used to connect pipes, valves, pumps, and other equipment to form a piping network. They provide a method for assembly, disassembly, and maintenance access. Gaskets are sealing materials placed between flange faces to create a pressure-tight seal by filling microscopic irregularities, preventing fluid or gas leakage under various pressure, temperature, and chemical conditions.

定义
Flanges are protruding rims, edges, or collars used to connect pipes, valves, pumps, and other equipment to form a piping network. They provide a method for assembly, disassembly, and maintenance access. Gaskets are sealing materials placed between flange faces to create a pressure-tight seal by filling microscopic irregularities, preventing fluid or gas leakage under various pressure, temperature, and chemical conditions.
工作原理
Flanges create a bolted joint connection between piping components, while gaskets utilize compression between flange faces to form a seal. When bolts are tightened, the gasket material deforms to fill surface imperfections, creating a barrier against media escape. The sealing effectiveness depends on proper bolt torque, gasket material properties, flange surface finish, and operating conditions.
材料
Flanges: Carbon steel (ASTM A105A350)stainless steel (ASTM A182 F304/316)alloy steelductile iron. Gaskets: Non-metallic (rubberPTFEgraphite)semi-metallic (spiral woundcamprofile)metallic (ring typeflat).

常见问题

What are the main types of flange faces?

Raised face (RF), flat face (FF), ring-type joint (RTJ), and male-female configurations for different pressure and sealing requirements.

How often should gaskets be replaced?

During maintenance shutdowns, when leaks are detected, or when disassembling connections. Replacement frequency depends on operating conditions and gasket material.
