Garlock ABRA-SHIELD™ Expansion Joints
Garlock launched of ABRA-SHIELD™ in 2018, an expansion joint material designed for abrasion resistance and sustainability in demanding high temperature operating conditions.
As the newest addition to Garlock’s family of abrasion resistant expansion joint materials, ABRA-SHIELD™ joined 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.

Material certifications, seal geometry and even seal color must also be factored in to allow for maximized seal life, minimized risk and reduced total cost of ownership for both the seal and the rotating equipment.
The most challenging operational environments for sealing mixers, agitators and pumps are often found in the food and pharmaceutical industries. When designing, selecting, or implementing a dynamic seal into operation in the food and pharma space, it is crucial to consider all the physical challenges the seal may face to ensure sealing success. Further, material certifications, seal geometry, and even seal color must also be factored in to allow for maximized seal life, minimized risk and reduced total cost of ownership for both the seal and the rotating equipment.
In this article, we will highlight some of the common environments found within these industries, discuss how the operating conditions affect seal design and selection, and finally, share some

The world has entered a pivotal moment in water treatment, and the challenges continue to worsen as municipalities grapple with the risk of encountering premature failure in elastomeric gaskets. Such a risk brings up several problems, including reduced efficiency, sudden equipment failure, costly maintenance and downtime, and perhaps worst of all — contamination.
Prior to 2013, gasketing products were not subject to the NSF61 (Drinking Water System Components – Health Effects) standard, leaving a critical gap in the safety and compliance of materials used in contact with potable water. However, as the demand for reusing treated wastewater grows, the influx of chlorine and chloramine levels — ensuring potability — has exposed the vulnerability of elastomeric gaskets. This has emerged as a serious issue.
In the ever-changing world of water treatment, it is important to address this challenge and explore innovative solutions to safeguard the reliability and longevity of gasketing

Metal Expansion Joints
The majority of nuclear power plants in the United States are approaching 40 years of age and some of the components installed during initial construction are beginning to show signs of wear. This is especially true of emergency diesel generator sets (EDGs) that provide backup power as necessary. Although varying in design, EDGs manufactured by Fairbanks-Morse, Cooper-Bessemer and Electro-Motive Diesel all produce excessive vibration. Propagated throughout a system, this vibration can cause various metal components to fail, often resulting in inoperability of the generators.
These failed components range from simple pipe supports and anchors to major piping for diesel oil or cooling water. There have been two common solutions that power plants have tried to remedy this problem, occasionally with temporary success. One solution is to use pipe loops to absorb some of the movement associated with the pipe’s thermal expansion. While these will support the

Variations of Compression Packing
Successful fluid sealing of valves and pumps cannot be accomplished without the appropriate sealing device. Whether using mechanical seals or compression packing, one must understand the specific needs of the application.
While mechanical seals in general are considered the superior sealing device, they are more expensive and less versatile than compression packing. Compression packing is more versatile due to the vast selection of materials used to make it and the various ways it is constructed. Materials such as vegetable fibers, man-made fibers, metals, graphite, and hybrids are all used to make packing. Construction types include braided, twisted, wrapped (rolled, folded), extruded, laminated, bulk, and die formed.
Construction types of compression packing each have variations within. This article will focus on braided
