HARDENING

SMS group has supplied and successfully commissioned a heat treatment facility and pipe threading line, which includes two 4-axis CNC threading machines, at Axis Pipe and Tube, based in Houston, Texas, U.S.A.

The two new plants for the Bryan, TX, works enable the company to produce OCTG tubes (Oil Country Tubular Goods) used in natural gas and crude oil production. With the new state-of-the-art equipment, Axis Pipe and Tube will extend its product range opening up new customer segments.

SMS group supplied a heat treatment line, including a natural gas-fired walking-beam hardening and tempering furnace, a water quenching unit and a 10-roll hot straightener, to produce tube grades of up to HCP110. The supplied pipe threading line features two 4-axis CNC threading machines, which operate on the principle of stationary tool and rotating tube. A hydrostatic pipe tester with a maximum test pressure of 15,000 psi, a finishing section and all pipe handling equipment for the threading line were also part of SMS group’s scope of supply. The pipe handling equipment is designed to prevent pipe-to-pipe contact after threading. The tubes and pipes processed on the threading machines will conform to manufacturing standards as per API 5CT.

Thanks to this project, Axis Pipe and Tube is now even better prepared to fulfill the ever more exacting quality and productivity demands of the market at present and in the future.
