Plain End Pipes and Tool Joint Forgings are ordered to specific metallurgical chemistries and are matched for physical properties, welding compatibility, weld strength and product integrity.

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.
