TimkenSteel, a manufacturer of alloy steel, as well as carbon and micro-alloy steel, located in Canton, Ohio, recently reported that it has developed a new process to manufacture high-pressure tubing (HPT) used for the production of low-density polyethylene. Moreover, the company has recently received its first order from a major petrochemical producer. TimkenSteel’s process begins in Canton where its special bar quality (SBQ) steel is forge-rolled and heat treated. It is then sent to TimkenSteel Material Services in Houston where it is bored and honed.
TimkenSteel recently entered into a supply agreement with A&A Machine & Fabrication LLC, of La Marque, Texas, to further process, market and sell HPT for low-density polyethylene customers. A&A completed reliability testing to ASME code on prototype tubing and processed that material to industry fabrication requirements in order to illustrate material performance. A&A and TimkenSteel then met with end-users to gain market acceptance of the material.
