Available size: 1.66” – 4” Completely flush OD & ID; Thread seal connection: Same thread form as SUPERMAX 2° load and 45° stabbing angle; Tension: 38-50% of pipe body yield. “W” series casing offers the extra strength of double butt joints and added ease in cleaning threads. Our casing is flush threaded inside and out and, because of its’ “W” series design, it does not require the use of a coupling. The outside diameter of each size casing will fit the hole drilled by the next larger size core bit. Steel Tubular Products USS-LIBERTY FJM ® is a flush joint connection with a true flush OD designed for clearance-critical applications. Applications include use as a repair liner where casing has been damaged by corrosion or wear. The proprietary thread form overcomes a typical weakness in flush joint connections – the compressive strength.
