Flanged Diaphragm Seal Introduction
A flanged diaphragm seal is a protective device that isolates the process medium from the measuring instrument through a flange connection. It is widely used in pressure, level, or flow measurement systems, especially in corrosive, high temperature, high viscosity, or easily crystallized media environments.
Application
■ Chemical and petrochemicals
■ Oil and gas
■ Pharmaceuticals and Food & Beverages
■ Water treatment and energy
Key Features
✔ Excellent protection performance
Made of high-quality materials such as 316L stainless steel, Hastelloy, titanium, etc., it can withstand strong acids, strong alkalis and extreme temperatures (-80°C to 400°C), and is suitable for corrosive environments such as chemicals, oil and gas.
✔ Precise and stable
The ultra-thin elastic diaphragm design ensures high sensitivity, combined with silicone oil or fluorine oil filling fluid to achieve fast response and long-term stability.
✔ Flexible adaptation
Provides a variety of flange standards (ANSI, DIN, JIS) and pressure levels (PN16 to PN420), supports customized sizes and connection methods, and is seamlessly compatible with mainstream instruments around the world.
✔ Maintenance-free design
The integrated sealing structure eliminates the risk of leakage, reduces downtime maintenance costs, and improves production efficiency.
How to select a diaphragm seal
When selecting a diaphragm seal, it is necessary to consider the medium, flange standard, working pressure/temperature, diaphragm material, connection method, etc. This can significantly improve the equipment life and measurement reliability.
