Bronx/Taylor-Wilson awarded contract for pipe finishing equipment

particular design of straightening machine is an example of the design that BTW offers to the market. The Bronx/Taylor-Wilson 6.CR. 11 six-roll design is used to straighten the top quality API and GOST quality pipes in the most arduous of mill conditions. The machines offer features including a hydraulic lift for ease of tube entry and electronic pressure sensing load cells for an accurate indication of straightening loads. In addition, the machines are supplied with the patented Compass computer aided setting system. Bronx International Inc – USA Fax : +1 330 244 1961

Bronx/Taylor-Wilson, USA, a leading manufacturer of straightening and hydrostatic testing equipment, has recently won a number of contracts. The company’s state-of-the-art equipment can be used to process cold and hot pipes of over 600°C, thin or thick walled tubes of over 50mm, and low or high yield strength alloys of over 1000MPa. The latest contract won by Bronx is from a new joint venture between a SouthAmerican company and a Japanese company. As part of the decision process, stringent testing required pressures that have never been accomplished on such high yield equipment for API standard 5CT/5L product diameter ranging from 177.8mm to 406.4mm. The hydrotesters will be designed to withstand an end load of 8043KN for 406.4mm OD casing. This end load is the highest of any product that will be tested at such diameters. The hydrostatic pipe tester will include the main machine and auxiliaries and will incorporate the Bronx/Taylor-Wilson proven collapsing sealing between the tube and testing head which has a lifetime of 10,000 testing times per piece. The tester is enclosed in a safety protective hood that includes lifting devices for tool changing and equipment with the possibility to place the tools outside of the protective hood. The controls are equipped with a pressure recorder to store the entire procedure of the testing from water filling to

pressure build up, to pressure-to-pressure releasing and the time of pressure testing. The data can be stored digitally and on paper, and individually sorted according to the time, lot, shift, product standard, outer dia- meter, wall thickness, and steel grade (steel type). The fully automatic machine can also be manually operated by push button.

The hydrostatic pipe tester will be equipped with an automatic self-checking function, fully automatic control, communication with upstream and downstream equipment and interfaces for checking signals. The machine has functions to transfer the necessary information of production and process to an upper level computer. Bronx/Taylor-Wilson will also supply two 6.CR.11 pipe-straightening machines. These machines will process a diameter range of 177.8mm to 406.4mm diameter at yield strengths above 165,000psi. This  The hydro pipe hold testing screen, part of Bronx’s technology

Brushes for pipeline weld cleaning

Osborn International, Germany, is the manufacturer of brushes and abrasives for use in industrial applications. Steel wire brushes are an ideal solution for the cleaning of welded seams. Wire brushes are a cost effective and practical method for removing welding cinder and beads that prevent the next seam from being applied. The use of cellulose and alkaline electrodes are insignificant, as a brush will carefully remove all types of cinder. A rotating wire brush will provide a clean welded seam without having to remove up to 30 per cent of the welding material, as is inevitable with a grinding disc. Any defects in the weld seam also become immediately visible, enabling any rework to be carried out promptly. The use of steel wire brushes reduces the number of seams by a claimed 30-50 per cent, and additional time needed for resoldering work can be avoided. Osborn pipeline brushes can be used for weld cleaning, internal or external cleaning, bevel end cleaning, removal of insulation coats and rehabilitation work. They enable long life, optimal brushing results and safe work. Osborn International GmbH – Germany Fax : +49 64 5158 8206 Website : www.pipelinebrush.com

Leading pipe supplier to the Central Asia-China pipeline project PJSC Khartsyzsk Tube Works, founded in 1898, is involved in the manufacture of pipes for oil, gas and water pipelines. The company’s production range includes pipes from 406mm to 1,422mm in diameter with wall thickness from 7mm to 32mm. There is a capability for external anticorrosion polyethylene and internal flow and anticorrosion epoxy coating. Khartsyzsk operates a management system certified according to ISO 9001, OHSAS 18001 and ISO 14001. The main preoccupation of the company’s plant is the project for construction of the Central Asia-China gas pipeline. This project requires pipes with 1,067mm in diameter and wall thickness of 15.9mm and 19.1mm. In order to carry out this order, the company use high-quality process materials and advanced technologies both for pipe manufacture and the application of external and internal coating. A monitoring system for the technological parameters is installed in the shops to ensure optimum management of all production areas.
