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.

Pipe Flanges: Key Considerations for Metal Hoses and Expansion Joints
While corrugated metal hoses and expansion joints can accommodate many different end fitting types, pipe flanges are one of the most common connections specified by customers. However, there tends to be a good deal of confusion industry-wide as to the proper use of pipe flanges on metal hoses and expansion joints. Here are a few things to keep in mind when helping customers with flanged assemblies.

The Potential Benefits of Investing in High Performance Expansion Joints
Material validation is a critical step when designing a high-performance expansion joint. Therefore, it is important to know what is on the inside of the expansion joint and not just the outside. There are numerous issues that could arise from improper material selection and layering construction that will ultimately affect the life and performance - November 03, 2023
From the outside, an elastomeric expansion joint looks to simply be made out of molded rubber. Part of the reason expansion joints are used in such a wide variety of applications is that the interior construction of a joint can be custom-designed to handle your specific application - materials of construction will depend on size, temperature, application, media, pressure (S.T.A.M.P.).

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,
