YOSON Diaphragm Gasket

Diaphragm gaskets, also known as chemical seals or hygienic seals are flexible enclosures/membranes. They act as protective barriers to several types of pressure elements. These seals are versatile, allowing constant pressure to escape while safely sealing the contents. Also, they fitted in conjunction with pressure gauges, switches, and transmitters. It can be used in extreme conditions and harsh weather.

Application of Diaphragm Gaskets

Application of Diaphragm Gaskets

Our diaphragm gaskets have a variety of uses. Pressure gauges use them to secure the pressure sensor from toxic compounds. They are designed for use in harsh environments and are suitable for a variety of manufacturing applications.

For example, they are used with pressure gauges, which are frequently exposed to harsh process environments. They are used to shield the instrument from potentially hazardous and harmful media. In some ways, diaphragm gaskets are used to prolong the life of any tool by defending it from damaging media that can be high in temperature, highly acidic, viscous, and contain extremely toxic combinations.

Materials We Used in the Production

We use different materials in producing the lower housing and upper housing of diaphragm gaskets.

Upper Housing. Carbon steel, zinc-plated for corrosion protection, is the standard upper housing content for Yoson diaphragm gaskets. Optional materials are 316L stainless steel, MONEL, Hastelloy, Titanium, and others.

Lower Housing. Because this portion of the seal is exposed to the process media, choosing the right lower housing material is critical. As a basic rule, the materials used are like those used for the rest of the pipeline system. It includes 304L Stainless Steel, 316L Stainless Steel, Titanium, Carpenter 20 Stainless, and more.

Types of Diaphragm Gasket

Based on your applications, the custom diaphragm gasket can be classified into:

Inline Diaphragm: It permits flow patterns and is installed inside various connectors. The seals are arranged in a pattern that inhibits system clogging and avoids contamination risks in the diaphragm over time.

Threaded Diaphragm: These are designed to mount straight on threaded process connections. Very compact in size to fit small areas.

Flanged Diaphragm: Intended for mounting directly on the process counter flange or clamping the diaphragm seal in-between process and covering flanges. This meets numerous standards, such as JIS, API, ASME, etc.

Sanitary Diaphragm: This type is created specifically for food and pharmaceutical applications, where bacteria formation must be avoided. FDA compliant to prevent bacterial spread.

Advantages in Different Industry

Spending money on a diaphragm gasket is definitely worth it. The cost is certainly not higher than the cost of the measuring device or the protection of its users. Here are a few additional advantages of diaphragm seals:

  • They aid in the prevention of fluid clogging and crystallinity.
  • They remove the chances of fluid corrosion or sensitivity with all these mostly conductive devices.
  • They allow the instruments to keep functioning in a broad range of temperatures and with a variety of toxic fluid flow and semisolids.
  • Depending on the process, certain threaded and flanged diaphragm seals allow for remote mounting via a capillary.
  • They contribute to the increased life span of the sealed components.

Custom Diaphragm Gasket for Industries

Chemical Manufacturing

Different types can be used in chemical manufacturing, whether inline, threaded, flanged, or sanitary diaphragm gaskets. They are gasketed and act as a safety barrier to prevent fluid leakage. The standard gasket can be customized to fit your chemical manufacturing applications.

Petroleum Refining

In the petroleum refining projects, our diaphragm gaskets are used to isolate a pressure measuring instrument from the process media. It is frequently used for most complicated monitoring tasks, such as when the atmosphere is immensely hot or cold. These are corrosion-resistant, leak-resistant, and superior in quality.

Food Industry

The sanitary diaphragm gaskets are used in the beverage industry. This type of gasket is FDA compliant, which means they are designed specifically for the food manufacturing industry. They help to prevent the spreading of bacteria.

Pharmaceutical Industry

For the pharmaceutical industry, sanitary diaphragm gaskets are also suitable. It makes the measuring pressure more reliable and safer –even in harsh working conditions. It is typically connected to the process transmitter, pressure gauge, and pressure switch.
