In industries such as chemical, petrochemical, oil, and gas, pressure measuring instruments often need to withstand corrosive, high-viscosity, crystalline, or high-temperature media.
Flanged diaphragm seals, with their unique structural design, can effectively isolate hazardous media, ensuring the long-term stable operation of pressure measuring instruments. They have now become an indispensable safety assurance device in process industries.
Product Features
The core advantage of flanged diaphragm seals lies in their robust construction and diverse configuration options, which enable them to meet measurement needs under a variety of extreme conditions.
▪ The diaphragm seal features a flanged design, accommodating pipe connections of all standard sizes and nominal diameters. This design ensures installation flexibility and compatibility.
▪ The special fluid (such as silicone oil) internally fills the seal, accurately transmitting media pressure to the measuring instrument. Different filler fluids with varying properties can be selected depending on the application environment to ensure optimal performance across different temperature ranges.
▪ All wetted parts can be manufactured from special materials selected based on the media characteristics, such as 316L stainless steel, tantalum, titanium, Hastelloy C276, etc.
Application industries
The superior characteristics of flange-type diaphragm seals enable them to play a crucial role in multiple industrial sectors, serving as vital components for ensuring production safety and efficiency.
▪ In the chemical and petrochemical industries, flange-type diaphragm seals effectively handle various corrosive media, protecting pressure measuring instruments from damage caused by corrosion, viscosity, crystallization, or toxic substances.
▪ For the oil and gas industry, the product's robust design and high-pressure tolerance allow it to withstand extreme operating conditions, ensuring accurate and reliable data at critical measurement points.
▪ In applications involving thick-walled or isolated vessels and pipelines, the specially extended design of the diaphragm seal easily handles these challenging installation environments.
▪ Flange-type diaphragm seals are also suitable for measuring other high-viscosity, easily crystallizing, or high-temperature media. Their flush-fit welded diaphragm design prevents media buildup, ensuring measurement accuracy.
As process industries continue to demand higher levels of safety and efficiency, flange-type diaphragm seal technology continues to advance, providing reliable assurance for pressure measurement applications in a wider range of fields, becoming a strong support for safe industrial production.
