Latest Patents
Ruddle's latest patents include innovative methods for producing seamless steel tubes that are suitable for use as grades of casing and line pipe. His first patent details a seamless steel tube alloy that achieves yield strengths in excess of 70,000 psi without the need for heat treatment. This alloy comprises specific percentages of carbon, manganese, vanadium, titanium, and nitrogen, with the balance being iron and incidental impurities. The process involves applying strains to the steel shell in a stretch reducing mill to provoke dynamic recrystallization.
The second patent outlines a method for manufacturing seamless steel tubes with similar strength characteristics. This method includes alloying the steel, forming it into a billet, and passing it through various mills to create the final product. The introduction of nitrogen and vanadium during the alloying process is emphasized, as they are predominantly present as vanadium nitride and titanium nitride.
