Plain end pipe is up settled and heat-treated full length by the Quench and Temper process to achieve uniform mechanical properties. The upset profile is designed to blend with the inside diameter of the pipe body with a generous radius giving a smooth transition from the thicker cross section of the upset to the pipe body. The smooth transition minimizes the stress concentrations.
