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.

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.

Case Study: Eliminating Epoxy Use on Flanges

GYLON EPIX™ is a family of gaskets that effectively seals a broader range of applications and is more forgiving during the installation process.  It allows the end user to save valuable turn-around time, reduce re-work, and lower costs, helping them to finish ahead of schedule and under budget.

GYLON EPIX™ features a hexagonal surface profile that provides the torque retention and blowout resistance of a thin gasket and the conformability of a thicker gasket.  GYLON EPIX™ Style 3504 EPX is a high performance, aluminosilicate microsphere filled PTFE sheet material designed for use in moderate concentrations of acids, and caustics, as well as hydrocarbons, refrigerants, and more.

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.

Cement Manufacturer

BACKGROUND

The customer experienced gasket leaks in their piping system.  This caused lost time due to repairs and clean-up efforts.

CHALLENGES FACED

Several issues that plagued the system – abrasive media stream caused gasket and flange erosion, and low strength bolts prevented the customer from using higher performance gasketing materials that require higher assembly stresses to properly seal.

GYLON EPIX™ 3504 EPX

OPERATING CONDITIONS

  • Media: Dry Cement
  • Temperature: 185°F (85°C)
  • Pressure: 102 psig (7 bar)
  • Class 150 Raised Face Flanges
  • Grade 2 Bolts (low strengths, 57ksi yield strength)

SOLUTION AND BENEFITS

The customer’s desire to have a sealing solution that could work with flanges in their current condition, as well as the lower strength bolt led to the evaluation of the GYLON EPIX™ 3504 EPX in a 6″ 150# raised face flange.  The 3504 EPX gasket effectively seals the damaged flange faces with the lower strength SAE Grade 2 bolts.
