LOW RESIDUAL STRESS U-BEND TUBING FOR SCC ENVIRONMENTS
This unique direct-to-bend manufacturing approach from RathGibson controls the residual stress controlled to 5000 psi or less in U-Bend tubing used in the chemical and power generation industries.
Posted: May 1, 2010
RathGibson (Lincolnshire, IL), a leading manufacturer of welded, welded and drawn, and seamless stainless steel, nickel, and titanium tubing, now has the capability to control the residual stress levels in U-Bend tubing for Stress Corrosion Cracking (SCC) alloys used in SCC environments. Contractors operating in SCC critical settings realize the necessity to reduce the stress to the lowest possible levels.
The company produces U-Bend tubing with the residual stress controlled to 5000 psi or less for SCC susceptible alloys. The effectiveness is verified by actual SCC testing. The tubing is fabricated at a state-of-the-art integrated in-line U-Bend Manufacturing Center, located in the Janesville, WI facility. ?The opening of in-line U-Bend Manufacturing was just the beginning,? said Dave O?Donnell, director of process and product development. ?As a company, we believe that meeting the diverse needs of our customers is essential. This controlled residual stress tubing is just our next step in our commitment to advancing the quality of U-Bend tubing.?
Low residual stress U-Bend tubing is extremely valuable in the chemical and power generation industries, including both fossil fuel and solar applications. With a unique direct-to-bend manufacturing approach, the process offers fast delivery with increased efficiencies and minimal in-process material handling. Using stainless steel, duplex stainless steel, super austenitic, and super ferritic/ferritic, U-Bend tubing is
offered across a wide range of tube ODs and wall thicknesses. All tubing complies with ASTM/ASME
A688/SA688 and/or A803/SA803 specifications are applicable.
RathGibson?s corporate headquarters are located close to Chicago in Lincolnshire, IL. Manufacturing
locations include Janesville; North Branch, NJ; Clarksville, AK (Greenville Tube); and Marrero, LA (Mid-South Control Line). In addition to the sales offices in Janesville, North Branch and Marrero, the company has also placed strategic sales offices in Atlanta, GA; Houston, TX; Shanghai, China; Manama, Bahrain; Melbourne, Australia; Seoul, Republic of Korea; Mumbai, India; Singapore; Vienna, Austria; and Buenos Aires, Argentina.
