A corrugated metal diaphragm is a circular, elastic sensing element that converts pressure changes into measurable displacement signals through a concentric ring-shaped corrugated structure. The primary function of a corrugated diaphragm is to isolate the medium and transmit pressure.
The standard material for corrugated diaphragms is 316L stainless steel, which not only possesses excellent mechanical strength and corrosion resistance but also maintains stable operation within a temperature range of -40℃ to +125℃. Other materials include titanium, tantalum, Hastelloy, and Monel alloys, which can withstand more demanding industrial environments.
Corrugated diaphragms are widely used in various industrial automation fields. In process control systems, corrugated diaphragms, as a key component of pressure transmitters, can accurately measure pressure changes in liquids and gases.
Applications of Corrugated Metal Diaphragms in Various Industries
| Oil & Gas | Oil and gas well pressure monitoring and oil pipeline pressure control |
| Energy & Electricity | Hydrogen fuel cell pressure monitoring and boiler pressure control |
| Food & Pharmaceutical | Tank level monitoring and process pressure control |
| Environmental Engineering | Seawater desalination pressure monitoring and wastewater treatment system |
| Aerospace | Hydraulic system monitoring and fuel pressure control |
