Complete cold finishing equipment MAIR Research has been awarded an order for the supply of the complete cold finishing floor equipment for a tube producer for a facility in the USA. The scope consists of several lines, suitable to process 300,000 tons per year of seamless tubing. besides boiler and mechanical tubes. The layout of the equipment was studied together with the customer to ensure an optimised production flow, minimising off- line and manual handling. elements toensure rigidityandsturdiness. The structure has no columns, to ensure easy accessibility to the work area for roller replacement and maintenance, and control of operation during the work cycle. Other features include custom- designed rollers according to the actual production range, and automatic setting of work parameters (angle of the rollers, work speed, etc). The production is mainly for tube according to various specifications of OCTG pipes for the energy industry, Each line includes a ten-roll straightening machine suitable to guarantee a finished tube of better than 0.5mm/m straightness. The main machine structure is composed of welded

The lines also include an NDT test bench and repair area; end cutting, including sample cutting and length optimisation; chamfering according to API norms (precise outer, inner angle and root face); visual inspection and rejects that fall into a cradle; and a high- pressure hydrotester with two heads, suitable for testing two tubes at a time up to 900 bar.

The equipment will be added to the customer’s existing tube sizing mill for the purpose of positioning the weld seam prior to reshaping the tube into squares and rectangles. The SOU is adjusted electrically and can be controlled remotely from a downstream position if desired. The customer chose the Rafter equipment over other competitive units because of the simple roll tool movement and design. In addition, the company was able to offer positive feedback from a previous customer. Competitive designs articulate the roll tools in a manner similar to that of a 2-roll, cross- roll straightener. However, the cross-roll method requires a more careful setup and special attention to the roll tooling design to be successful.  Rafter Equipment Corp – USA Fax: +1 440 572 3703 Website: www.rafterequipment.com
