Omega Seal Profile: A More Robust PSA-Backed Sealing Solution

Standard D-Profile - Omega Profile SealsCustomers often call with various sealing challenges. But sometimes their dilemmas can be solved with more robust solutions instead of direct replacements. For example, when a customer is having issues with a PSA-backed hollow seal that keeps peeling away from the bottom surface.

If you need to seal a box with a lid, you may need a 4-corner gasket to seal the contents from dirt and moisture. If you use a solid gasket, the compression force may be too great to effectively close the lid. Using a hollow seal reduces the compression force by orders of magnitude, but it comes with its own set of challenges.

A hollow seal for a box will most often seal between two flat surfaces. The bottom surface will be flat for adhesion to the box, while the top surface is curved to engage the lid as it is seated on top of the seal. However, the disadvantage of this design is the tendency of the flat portion to lift off the bottom surface. Figure 1 illustrates this phenomenon with standard Parfab profile D015.

Elastomer Seals for Instrumentation: In-Line Process

High Performance Elastomer Seal for InstrumentationGallagher recently released our High Performance Elastomer Seals for the Instrumentation Industry White Paper.  This was written by Russ Schnell, an Elastomer Consultant contracted by Gallagher Fluid Seals, and a former Senior Application Engineer with the Kalrez® perfluoroelastomer parts business at DuPont.  This white paper is now available for download on our Resources page.

Below is the first section of the white paper, diving into applications where the measurement is made at the process and the results then transmitted to a control system.  This section will review the four types of in-line measurement devices, all involving slightly different elastomer sealing applications.

In-Line Process Applications

Flowmeters

Flowmeter - Elastomer Seal for InstrumentationFlowmeters are used to measure the flow of liquid. In this section we will only consider the measurement of liquid flow in a closed piping system. Several examples of flow measurement devices include: flowmeters, Venturi tubes and orifice plates.

Note that these devices are “in-line” and require isolating the process line to remove and repair, or replace the measurement device. Shutting down a process to remove a device is time consuming, involves loss of production, and may require specific procedures to protect the operators and environment when a line is opened. All of these devices require seals to prevent leakage of the process to the environment and the elastomer seals should last the life of the flowmeter. For aggressive chemicals or high temperature applications, FKM or FFKM seals are an excellent choice. These products offer a long service life and resist deterioration in harsh environments.

NEW! Process Seals Webinar – Flavor Transfer

Process Seals - Flavor TransferGallagher Fluid Seals recently made our Process Seals Webinar available on the website.

Food & Beverage, Pharmaceutical, and Chemical Processing industries have different requirements than typical seals. Process seals need to have multiple media resistance. Unlike a traditional seal that only needs to be concerned with the media running through it, process seals also have to be designed to withstand the cleaning media being used.

This is the third and final section of the Process Seals Webinar, presented by Gallagher Fluid Seals & Dichtomatik Americas. This video discusses flavor transfer for seals used in processing.

This webinar was produced in conjunction with Dichtomatik Americas,  a Freudenberg brand.  With a broad array of products and materials, but more importantly comprehensive knowledge and technical expertise, Dichtomatik has earned its title as market leader for sealing solutions in food & beverage, pharmaceutical, and chemical processing industries.

Vesconite Bushings for Railway, Transportation

Vesconite has over several decades been successfully used in a number of railway applications. The material’s self-lubricating properties make it well suited to railway components that are prone to metal on metal wear and require regular greasing. Not only will a switch to Vesconite bushings avoid long periods of downtime, the noise and squeal issues commonly associated with rolling stock, is significantly reduced. With a resultant reduction in rolling resistance, considerable power savings have been noted with the use of Vesconite components.

Vesconite Hilube on Tram Drive Bushings

Vesconite - Tram Bushings for RailAustralia – An Australian tram operator continues to order approximately 100 Vesconite Hilube motor axle bushings a year, following its successful introduction to the product in 2006. The motor axle bushings, which require no lubrication and are wear resistant, have completely replaced the standard metal main drive H-class-tram bushings, which had been in use prior to the introduction of the polymer product.

NEW! GYLON EPIX™ Webinar Now Available

GYLON EPIX™Gallagher recently added the GYLON EPIX™ Webinar to its website. This video is a recorded webinar discussing GYLON EPIX™ – The Next Generation in PTFE Gasketing.

This material is a newly developed family of PTFE gaskets. It is manufactured using a patented, profiled surface based on our proven Fawn  (Style 3500), Off-White (Style 3510), and Blue (Style 3504) GYLON® to create highly conformable materials for optimum sealing performance.

GYLON EPIX™ will provide superior functional performance by combining the traditional attributes of GYLON® with an innovative surface design. It offers a broader range of applications than traditional PTFE gaskets that are used in worn and pitted flanges. In addition, GYLON EPIX™ delivers the tight sealing and load retention properties of 1/16” (1.6mm) and the conformability of 1/8” (3.2mm). The hexagonal profile provides improved compressibility and recovery. The profiled surface reduces the contact area during initial compression to concentrate the compressive force of the flange for improved sealability.

Garlock GYLON EPIX™Designed for increased compressibility, it improves performance in misaligned flanges. The consolidation of two thicknesses to one reduces the need to inventory multiple thicknesses. Garlock is dedicated to providing real sealing solutions that meet real world sealing needs. With an improved design, color-coded materials, and single thickness, GYLON EPIX™ makes sealing easier.

Introduction

The term instrumentation covers a wide variety of applications. In the broadest sense, instrumentation may be considered as any equipment used for measurements. This equipment may be in a process stream and include devices such as flowmeters, pressure gages, and inline probes. Data from these devices are used for process control. In automobiles, sensors are used for a variety of applications including measuring the exhaust stream to “tune” the engine to yield maximum performance. Analytical laboratory instruments such as chromatographs and flame ionization detectors are used to determine the composition of samples. Instruments are used in the medical industry for product analysis as well as analysis of blood and urine samples. Of course this is only a partial list of the many applications involving instruments.
