Gallagher 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.
There 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 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® 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.
There 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:
There are a multitude of options when it comes to selecting the most suitable sealing product for your application. And for those who are not familiar with sealing technology, the number of options can be really confusing. Gallagher can help.
We pride ourselves on being “The Seal Specialist”, and our engineering department is ready to help seal your toughest application. But where do you even start? Keep reading to learn more about some of the fundamentals of seal design and fluid power sealing theory from our partners at Parker.
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.
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.
Thordon is the world leader in grease and oil-free bearing solutions, and now they have a mechanical face seal as part of their product offering: Thordon TG100.
With the Thordon TG100 propeller shaft seals, workboats no longer have to put up with the maintenance hassles and shaft wear commonly experienced with stuffing boxes. Stuffing boxes often cause excessive shaft wear and are not considered a reliable solution in emergency situations.
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.
