Paul Horn supplies tooling for machining pipes and sleeves used in oil and gas production, creating cost-effective OCTG (oil country tubular goods) solutions for use in API- and GOST-compliant applications. The tools are designed to deliver a productive edge over other tools in the areas of handling and service life.
The tool systems are available with standard machine interfaces including VDI, polygonal and round shank holders as well as flange-mounted on turrets. Both the screw clamp and the ground geometries of Horn’s S117 and 315 systems, together with carefully matched tool holders, enable effective chip management.
There are no expensive parts such as chip breakers or shims to install, allowing customers to make significant savings. The precise interchangeability provided by the precision insert seats reduces the number of tool adjustments needed.
During thread cutting in API- and GOST-compliant applications, the S117’s numerous teeth enable the number of cuts to be minimised. The 315 system has three cutting edges, making it ideal for premium joints that permit no more than three teeth per cutting edge. The tool carrier is designed to work with the insert, increasing the stability of the system.
In applications involving pipes with profiles that comply with ANSI/API-5L, Horn offers tool solutions for pipe end finishing. The milling heads can be used on pipe ends with a wall thickness up to 50mm. Integrated rollers compensate for any roundness errors.
Horn has expertise in machining a range of materials, from the easy-to-machine options of J55-K55, L80 and P110 to Q125 and on to high alloyed materials like 13Cr or 28Cr. Increasing drilling depths and more aggressive operational environments mean that these corrosion-resistant alloys have become a focus in pipe manufacture, especially in HPHT (high pressure high temperature) fields.
Horn’s HiPIMS coatings IG3 and HS3 exhibit smooth cutting properties, high heat resistance and minimal built-up edge. Tool geometry, substrate and coating are adapted to meet the requirements of each application.
