Dogbone Expansion Joints — La Favorite Ind.
The Evolution of Construction Materials
In the 60+ years that Dogbone Expansion Joints have been in service in the power generation industry, numerous rubber compounds, bulb core and fabric reinforcement materials have been utilized in the construction. In the last 30 years La Favorite has worked hard to ensure that the best possible product is offered to our customers. Staying in touch with the power generation industry has allowed us to learn the challenges they face and how we could utilize industrial material improvements to increase quality and reliability.
The original Dogbone Expansion Joints of the 1950’s were constructed with cotton duck fabric reinforcement. Since this time synthetic materials have been incorporated to offer greater reliability and strength. Rayon and Polyester were the earliest choices due to their improved strength and light weight. After years of case studies throughout the industry that involved polyester use, La Favorite began investigating an upgrade in fabric materials to offer greater reliability in service. Nylon offers increased strength, greater flexibility, better work-ability in regards to construction and splicing and resistance to wicking of liquids that it may come into contact with should the rubber cover become compromised.
Cover materials have varied greatly over the years. Natural rubber, Chlorobutyl, Neoprene and more recently EPDM have all been tried. EPDM has higher heat resistance, but unless combined with an equally heat resistant fabric, provides no additional protection. EPDM has also shown inherent problems in regards to its lack of oil resistance. Specifically, turbine bearing oil has been found to cause such degradation of EPDM covers as to have caused failures. Therefore, EPDM as far as we are concerned, has very limited application in Dogbones and should only be used in very specific or unusual circumstances. With many bearing oil caused failures, La Favorite reached the conclusion many years ago that Neoprene’s inherent oil resistance as well as good heat resistance and superior bonding is the best overall material for this product.
What we offer
Over the years there have been numerous design specifications created by a multitude of Condenser manufacturers. Along the way La Favorite Dogbones have been right there to fit the bill. We have taken a more tailor made solution to this wide variation as opposed to a “one size fits all” approach. Many condensers, through years of operation, are out of manufacturer’s alignment specifications and require unique solutions to compensate. As such we offer 14 different sizes of Dogbones to suit any number of operating conditions and offer ease of installation. Additionally we offer the unique ability to transition between different size expansion joints utilizing our exclusive splicing technique. All this combined means our customers need not reduce the quality and construction quality of their Dogbone Expansion joints when out of specification conditions arise.

This kind of expansion joint for turbine exhaust represents the most common type of connection used in large plants such as power plants.
Its main function is to absorb different thermal expansions that are generated between turbine and condenser.
It is usually made with Neoprene rubber reinforced with embedded stronger textile layers.
It is made of a central flat plate of uniform high thickness, and two lateral expansions (bulbs), which are intended to allow attachment to the clamps of the metal parts that need to be connected.
Their normal operating characteristics are:

Design, Fabrication & Installation Services
The expansion joint decouples the steam condenser from the steam turbine. One of the principle functions of the expansion joint is to absorb the differential thermal expansion between the steam turbine and the condenser while imparting minimal forces and movements on the turbine exhaust flange. RetubeCo specializes in installation, repair or replacement of elastomeric (rubber) dog-bone type expansion joints.
Replacement of the dog-bone expansion joint is often performed during a condenser retubing, but may require intervention during operations to perform repairs. It is critical that the dog-bone expansion joint be installed properly to avoid air inleakage into the condenser. An improperly installed, or leaking dog-bone will negatively impact condenser performance. RetubeCo has pioneered onsite vulcanizing of the dog-bone expansion joint with a newly designed & engineered portable system that minimizes the space that conventional vulcanizing systems require.
Our full-time engineering team can provide detailed designs for a replacement expansion joint, while our in-house machine shop can fabricate the necessary hardware. Installation is performed by our expansion joint specialists with oversight by the engineering and project management team.

Rubber Expansion Joints- Especific Purposes
One of the main functions of the Dog Bone Expansion Joint is to absorb the differential thermal expansion between the steam turbine and the condenser while imparting minimal forces and moments on the turbine exhaust flange. Steam turbines come in a variety of exhaust configurations such as down exhaust, axial exhaust and top exhaust. Each configuration has unique design and performance requirements for the expansion joint. The expansion joint must perform satisfactory under a wide range of operating conditions to ensure reliable operation of the turbine condenser system.
