OCTG machining

OVER the past decade, Danobat has emerged as one of the major suppliers of individual machine tools and complete turnkey lines to equipment manufacturers in the OCTG (oil country tubular goods) segment of the oil and gas industry. Customers for Danobat’s products include some of the most important OCTG manufacturers. For anyone involved in the machining of difficult-to-machine materials such as high specification corrosion resistant alloys, the last thing they need is a problem with a finish machining operation that could result in damage to a high value component and delays in meeting delivery dates. The challenge that Danobat has addressed is the design and development of machine tools and systems capable of dealing with increasing pipe thicknesses; tougher, more corrosion-resistant materials; and the demand for greater types of threads for pipe ends and couplings, all prompted by the fact that drilling is reaching deeper and deeper beneath the earth’s surface. Danobat machine tool technology embraces the machining and threading of pipe ends and complete machining of the couplings that join pipe lengths together. One of Danobat’s specific areas of OCTG expertise is sawing technology

for drill pipes, a process that involves two Danobat CP sawing machines that move along a slide in order to adjust the pipe length as required. Powerful software optimises the machining process, integrating adaptive intelligent cutting and blade deflection control to automatically adjust blade speed and downfeed for optimum performance, straightness of cut and maximum blade life. Once cut to length, individual pipes can be thread to API, GOST or premium standards by rotating the pipe in Danobat TT and TT-B horizontal lathes. These machines are designed on a modular basis using finite element analysis, with the five models in the TT range covering pipe diameters up to 20". The main features of these lathes, which offer the choice of headstock on either the left or right side, are four-axis simultaneous thread cutting and spindle motor power up to 170kW, depending on the model.

New Otto Fuchs commission

LARIKKA Ltd. Koivuhaantie 7 B FI-01510Vantaa, Finland Tel. + 358 20 712 1444

HERTWICH Engineering GmbH, part of the SMS group, has successfully commissioned two two-chamber melting furnaces at Otto Fuchs in Meinerzhagen, Germany. The annual production is 50,000t, and the furnaces are equipped with regenerative heating systems that help to reduce energy consumption and emissions. The new Ecomelt melting

furnaces from Hertwich Engineering are charged from above. They operate with integrated scrap preheating and use the immersion melting process, which enables them to achieve high metal yield.
