PTC Liberty Tubulars is a market leader in the processing and finishing of Seamless (SMLS) pipe. SMLS pipe is made by heating a solid steel billet, piercing it with a mandrel to form a tube, and then stretching or rolling it to the desired length, diameter and wall thickness. We finish SMLS up to 7.625” outside diameter (OD), and provide threading up to 13.375” OD, with API and semi-premium connections available in our 300,000 square foot Houston, Texas pipe processing center.
