13 Common Questions Regarding Rotating Shaft Seals
Rotating shaft seals can be found in virtually every facet of daily lives—household appliances, cars and trucks and across industries. Though often treated as a commodity product, their failure can result in costly downtime and lost productivity. Despite their use in countless applications, many still have basic questions about how to use them. Here are some frequently asked questions.
1. What is a retainer plate (cover plate),

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.
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.

Garlock Style 215 Helps Steel Products Manufacturer With Harsh Acids
Garlock Style 215 Expansion Joints are PTFE concentric spool-type flexible couplings that are designed to reduce noise and compensate for expansion, contraction, and minor piping misalignment in chemical processing, air conditioning, and heating systems.
The complete assembly includes a fluorocarbon resin PTFE body, electroless nickle-plated ductile iron flanges, polyethylene-covered restriction zinc plated bolts, and stainless steel corrosion-resistant reinforcing rings.

BACKGROUND
Construction of two new facilities including a hot rolling mill.
CHALLENGES FACED
The plant was in need of expansion joints that could handle chemicals on their pickling lines. Pickling is a metal surface treatment used to remove impurities, such as stains, inorganic contaminants, rust or scale from ferrous metals. A solution called pickle liquor, which contains strong acids, is used to remove the surface impurities. It is commonly used to clean steel in various steel making processes. The line required an expansion joint with a PTFE tube to handle the pickle liquor which included hydrochloric and sulfuric acid, but a very short overall length for installation.

How the raised surface profile of PTFE sheet gasket helped a midstream oil and gas processor address leaky pipes
Bolted flange-gasket connections in process piping systems are common and given little thought – unless they start to leak.
Chronic leakage proved to be an issue for one of Garlock's clients, a midstream oil and gas processor and services provider. The site processes, stores, and transports natural gas, liquefied natural gas and petroleum products. Garlock was brought in to

Garlock's BLUE-GARD 3300 for Cold and Refrigeration
In the late nineteenth century, Garlock devised a better way to seal piston rods in steam engines. Since then, sealing materials have been developed for specific various industrial applications. Over the years, different manufacturing processes such as calendering and beater addition have improved the performance of fiber sheet gaskets for these applications; however, design concepts for their formulation remain similar regardless of manufacturing

Controlling Leaks with Bearing Isolators
Today’s demanding applications call for other sealing methods. One alternative is the bearing isolator. Advances have created units with little frictional drag and a service life that is up to 65 times greater than that of a radial lip seal.
As radial lip seal technology evolves, new materials, geometries and configurations are being tested for their ability to reduce or overcome frictional drag between the lip and the shaft.
