David Siverling is one of three founding partners of OCTG, L.L.P. Siverling, originally from the Pittsburgh, PA area, was hired into the industry in 1984 by Unaspect, Inc., as an Ultrasonic Inspections Manager. While at Unapect he developed one of the first portable Ultrasonic Full-Body Tube Testing Systems (FLUT).
He subsequently opened his own company, Tubular Ultrasound, Inc.(TU), in 1985. TU provided simple, 4-channel ultrasonic testing of the weld seam on welded oilfield tubulars to domestic tube mills.
To improve its level of FLUT services, TU designed and assembled an improved Full-Body Test System, funded in part by a US Department of Energy grant under the Energy Related Inventions Program (ERIP), a federal government grant program in which only seven-tenths of one percent of all ERIP applications receive funding. The first improved TU system was then immediately contracted by the US Steel seamless tube mill in Fairfield, AL to replace the mill’s $4 Million Mitsubishi Test System, which at the time had failed to certify for most major oil companies. As a result, TU received an annual open purchase order from US Steel for FLUT inspection services, which continued for the following 10 years. As a testament to its technological innovation and proficiency,the original TU UTFL system is still in service and remains the primary Off-line UTFL system inspecting Fairfield mill production, now 26 years later.
In 2004 OCTG acquired its first threading equipment from RMSM: One high-speed PMC casing line, and one Mori Seiki CNC thread line. To date, no threading firm in the U.S. uses mill-speed threaders, owing to the significant equipment and maintenance costs. This equipment is manufactured by one firm, PMC (Pipe Machinery Corporation), oneline costs approximately $12 million, delivery is approximately two years, and replacement parts and post-sales service are difficult to obtain. PMC threaders have two significant advantages, however: they are very robust, and their cycle time is 17 secondsper length, compared to three minutes for a CNC type threader. All other U.S. third-party threading services companies in the oilfield tubular industry employ CNC threaders,which are lightly-built, cheaper ($1M/pair), immediately available, and substantially slower.
Within several years after the initial step, the RMSM PMC high-speed line (Range III) was renovated and installed at the OCTG Houston facility, and has since then been operated and maintained by OCTG. An additional Range III PMC thread line was addedto the facility in 2007, and installation of a third PMC line (Range II tubing) has recently been completed at the facility. With these additions, the OCTG Houston facility currently(2009) boasts substantial middle-level threading capacity: two double-ended PMC casing threading lines (4 1/2 “ – 13 3/8” OD), one double ended PMC tubing threading line (2 3/8” – 5 1/2” OD), and one double-ended Mori Seki CNC casing thread line (4 1/2” –13 5/8” OD)
