Food Processing – Fried Snack Foods

CUSTOMER

A major diversified food & beverage manufacturer, with facilities located in all regions across the globe.

BACKGROUND

The customer had persistent problems when sealing hot oil applications on its bulk snack food fryers across several production sites. Build-up of polymerised vegetable oil on the flanges caused unsightly mess, maintenance complications, financial implications, and posed a significant fire risk.

CHALLENGES FACED

As well as ensuring that the sealing material was compliant to FDA and EN1935 standards, the challenge was to ensure that the gaskets would perform well under the difficult conditions presented by the high oil temperatures. Additionally, because the production line was also subject to regular and aggressive cleaning cycles, the gasket material was required to be compatible with other aggressive chemicals across a broad pH range.

Style 404 Expansion Joint for Abrasive Applications

Abra-Line Style 404The ABRA-LINE™ family of products was developed for highly abrasive applications typically found in the power generation, fertilizer, mining and chemical industries. These may include flue gas desulphurization systems, phosphate mining, dry bulk power transfer systems, tailings and slurry applications. Our proprietary urethane formula was designed to reduce wear and extend
service life.

Style 404 Expansion Joints are specially designed for full vacuum abrasive service applications. The tube material is a proprietary urethane formulation. Style 404 can be constructed as a single or multiple arch design. It can also connect pipe flanges in concentric or eccentric tapers, to join piping of unequal diameters.

Observation
A stainless hosing was used and would continuously fail due to abrasion on the leading edge of the hose. The hosing would last for 3 to 6 months before replacement.

NEW Expansion Joint Material – ABRA-SHIELD™

Garlock is excited to announce the launch of ABRA-SHIELD, a new expansion joint material designed for abrasion resistance and sustainability in demanding high temperature operating conditions.

ABRA-SHIELD™As the newest addition to Garlock’s family of abrasion resistant expansion joint materials, ABRA-SHIELD will join ABRA-LINE® and Natural Rubber to provide a variety of liners that cater to increased abrasion protection. ABRA-SHIELD will be an option for use with a number of expansion joint products that Garlock offers – including styles 204, 206, 7250, 8400 and 9394. These expansion joints also provide high levels of protection from stress, misalignment, vibration, noise, shock and corrosion.

In abrasion resistance testing – which provides data to compare materials and predict the lifetime of a material or coating – ABRA-SHIELD provided 50% higher abrasion resistance than standard EPDM (ethylene propylene diene monomer rubber). ABRA-SHIELD will be the recommended solution in abrasive applications (such as slurry, ash and brine) with sustained or spiked temperatures between 180°F and 300°F. For temperatures outside of this range, other materials in Garlock’s family of abrasion resistant expansion joints would be suggested.

Below is the first section of the webinar, diving into what drove Garlock to create this new material, and how GYLON EPIX™ provides the benefits of both a 1/16″ and 1/18″ thick gasket in one, universal, 3/32″ thickness.

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.

GYLON EPIX™ Distributes Load Evenly

GYLON EPIX™ is a newly developed family of PTFE gaskets. It is manufactured using a patented, profiled surface based on our proven Fawn, Off-White, and Blue GYLON® to create highly conformable materials for optimum sealing performance.

THE EPIX™ DIFFERENCE

GYLON EPIX™ and a traditional full face gasket were installed in a 3”-150# flat face flange at 120 ft.lbs. with pressure sensitive film.  The film revealed that the traditional material saw heavier loading-near and around the bolts, and lighter loading at the points furthest from the bolts. The GYLON EPIX™ was able to distribute the load more evenly and prevent the low loading phenomenon.

GYLON EPIX™ with Pressure Sensitive Film

The pressure sensitive film was then analyzed with special software that translate the various shades of red into a full color spectrum that provides a better visualization of the stresses that were developed on each of the gaskets. Again, while the traditional gasket saw areas of lower stress (green and blue areas), the hexagonal pattern in the GYLON EPIX™ concentrated and distributed the stress more evenly across the entire gasket.
