RathGibson, USA, a manufacturer of stainless steel, nickel, and titanium welded, welded and drawn, and seamless tubing and pipe, uses its experience and technical expertise to guide customers in the selection of tubing or pipe. The company educates its customers to think in terms of requirements, such as corrosive environment, dimensional limits and strength. “Too often, customers choose tubing based upon the tubing’s production process, such as welded, welded and drawn, or seamless,” explained RathGibson’s Dave O’Donnell, director, process and product development. “There are times when each of these options

is appropriate; however, the requirements that will be placed on the tubing product itself should always be the crucial determining factor in selection.”
