管箍

A ferrule is a compression fitting component used to create secure, leak-proof connections in sanitary tubing systems.

技术定义与适配语境
典型 管箍 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 ferrule is a precision-engineered ring or sleeve, typically used in sanitary fittings to connect tubing sections securely. It functions by compressing against the tubing when tightened with a nut, forming a tight seal that prevents leaks and contamination. In sanitary applications, ferrules are designed with smooth, crevice-free surfaces to meet hygiene standards and facilitate easy cleaning.

定义
A ferrule is a precision-engineered ring or sleeve, typically used in sanitary fittings to connect tubing sections securely. It functions by compressing against the tubing when tightened with a nut, forming a tight seal that prevents leaks and contamination. In sanitary applications, ferrules are designed with smooth, crevice-free surfaces to meet hygiene standards and facilitate easy cleaning.
工作原理
The ferrule works on the principle of compression sealing. When a nut is tightened over the ferrule and tubing, the ferrule deforms slightly, gripping the tubing tightly and creating a metal-to-metal seal against the fitting body. This compression ensures a secure, leak-proof connection that maintains integrity under pressure and temperature variations.
材料
Stainless steel (AISI 304316L)brassor plastic (e.g.PTFE) for specific applications. Sanitary ferrules are predominantly 316L stainless steel for corrosion resistance and hygiene.
Size Range
1/4" to 4" (6mm to 100mm)
Surface Finish
Ra ≤ 0.8 μm (32 μin) for sanitary applications
Connection Type
Tri-clamp, bevel seat, or face seal
Pressure Rating
Up to 150 psi (10.3 bar)
Temperature Range
-40°F to 400°F (-40°C to 204°C)
标准
ISO 2852DIN 118513-A Sanitary Standards

常见问题

What is the difference between a ferrule and a fitting?

A ferrule is a component within a fitting assembly. The fitting includes the ferrule, nut, and body; the ferrule specifically provides the sealing action by compressing against the tubing.

Why are sanitary ferrules made of 316L stainless steel?

316L stainless steel offers superior corrosion resistance, especially against chlorides and acids, and is non-porous, making it ideal for hygienic applications where cleanliness and durability are critical.
