Our IPSCO Koppel operation offers an extensive line of seamless tubular products. These products are manufactured at IPSCO Koppel's plant located in Ambridge, Pennsylvania (near Pittsburgh). IPSCO Koppel is a premier producer of seamless oil country tubular goods, drill pipe, coupling stock and line pipe used in the exploration, production and transmission of oil and natural gas. 

Seamless products are manufactured from cast round billets produced in an electric arc furnace and ladle refining facilities located in Koppel, Pennsylvania. In Ambridge, solid cast round billets are heated in a rotary hearth furnace to temperatures over 2000 degrees Fahrenheit. Billets exit the rotary furnace to the piercer for conversion to tube hollows. Hollows move through our mandrel mill where wall thickness is generated through an 8-stand floating mandrel mill process. Tubes exit the mandrel mill to the stretch reduction mill where they are rolled to diameter. After the stretch mill process, tubes are cut to length for finishing. Finishing and further processing operations include Premium and API production tube upsetting, normalizing, quench and temper, straightening, threading, EMI Inspection, hydrotesting and coating.
