FEP-Lined Expansion Joint for Chemical Processing

FEP-Lined Expansion JointGallagher Fluid Seals represents a number of expansion joint manufacturers, enabling us to provide an expansion joint for any piping system in any industry.  One of our more popular expansion joints is the GUARDIAN® 306 EZ-FLO® by Garlock.

It’s a spool-type expansion joint featuring an FEP lining that is fused to the body of the expansion joint.  The GUARDIAN® 306 EZ-FLO® is designed for the chemical processing and pulp & paper industries, where its ability to resist corrosive attack at normal and elevated temperatures and pressures is unequaled.

When to Use Segmented Gaskets

segmented gasketsThere are a number of situations where your product or process may require segmented gaskets.  Because of how sheets of gasket material are manufactured, some pieces of machinery are too big to utilize a single-piece gasket.

But you can also use segmented gaskets to get better yield from a sheet of gasketing material, minimizing the waste generated with centers.

_______________________

O-Rings are still considered the “go-to” sealing element in many applications.  They can seal a wide range of pressures, temperatures, and tolerances.  They also require very little room, are readily available, and easily sourced.  But there are applications that may be better suited with an alternate type of seal, such as a double chamfer radial seal.

In a recent blog post, our partners at Parker discussed the advantages of using a double chamfer radial seal.

GORE® Gasket Tape Gets an Upgrade

GORE® Gasket Tape is a 100% ePTFE form-in-place gasket that delivers worry-free sealing performance for large steel flanges (Series 500) and large glass-lined steel equipment (Series 1000). While this product has a number of advantages, GORE® has now made their gasket tape line even easier to use.


Improved installation-aid adhesive.

GORE® Gasket Tape - New Backer vs. Old BackerGORE® has upgraded the removable adhesive backer on GORE® Gasket Tape Series 500 and Series 1000 to a new higher strength material. This ensures that when the backer is removed at installation, it peels away in one easy-to-remove piece.

When To Use Metal Hose

Use Metal HoseThere are many factors to be considered when choosing the right type of hose for your application.  There are many different types of hose available on the market. They include metal, rubber, composite, PTFE and fabric. The decision of which hose type to buy depends on the application for which the hose is being used.

Metal hose is ideal for absorbing vibration, misalignment correction, thermal expansion or contraction of piping systems, and protecting equipment from excess motion.  Typically, metal hose is used when no other (non-metallic) constructed hose will work.  In other words, metal hose is used as a last resort.

Here are some of the factors that should alert you it’s time to use metal hose:

Installing an O-ring in a face seal gland is among the easiest of all installations. However, that doesn’t mean that there’s not potential for errors. Watch the video below from Parker to learn how to install an o-ring properly on a face seal gland.

VIDEO: Gore GFO Fiber vs Graphite/PTFE Packing

When tested alongside generic graphite/PTFE packing, packing made of 100% Gore® GFO® Fiber achieves better results for all key attributes: creep resistance, retention of lubricant, sealability, and stability (shrinkage).

The differences in performances for each generic packings will have an impact on the operational costs.

GORE GFO
Based on calculations for a 100 psi (6.9 bar) pump, 2 inch saft (50 mm); Drip rate 25,000 gallons (94.6 m3)/ year; Packing = $40; Replacement of packing = 3 times per year; kWh = $0.12

Understanding the Forces That Impact Soft Gasketing Performance

soft gasketing materialGaskets are often an afterthought when it comes to the well-being of a plant or process, as their cost is often negligible in the grand scheme of things.

Gallagher Fluid Seals stocks soft gasketing material from various manufacturers in many different thicknesses. Read on to better understand how to choose the correct gasketing material for your specific application.

To discuss soft gasketing, we must also understand the forces at work within a bolted joint flange assembly, also known as a BJFA. This understanding is important as these forces affect how a soft gasket performs and how long it lasts.
