Energy Method in Stretch Reducing Process of Steel Tube

2008-11-1 According to the theories for stretch reducing process and steel tube plastic deformation, the energy meth od was used to mesh the rolled deformation zone of the steel tube into the upper limit elements, and an admissible velocity field was constructed to deduce a series of formulas of the inner virtual power consumption of deformed bodies.

Electrical Resistance Welded Tubing (ERW)

Hot Stretch Reducing. Hot Stretch Reducing is an additional process for ERW products. This process involves taking the ERW tube, heating and passing the product through a series of rollers that reduce the size of the tube in one relatively fast operation. This is advantageous for customers, improving size ranges that PTC Alliance can offer.

Energy Balance in the Rolling of OCTG on a Stretch

2016-5-17 Most modern tube-production units (TPUs) include mills designed for rolling without a mandrel. This class of mills includes stretch-reducing mills (SRMs) and extracting-sizing mills (ESMs). The use of an SRM makes it possible to expand the range of tubes that can be made on a TPU thanks to an additional reduction of outside diameter up to 70%.

Numerical Simulation of Seamless Tube’s Stretch Reducing

The stretch reducing process is the last hot deformation process of the hot-rolled seamless steel tube’s production. Its role is to decrease the tube’s diameter under the large tension and expand the range of product specifications. But the stretch reducing process often results in wall thickness tolerance at the head and end of the tube.

TUBE AND PIPE MILLS Casey USA

The seamless pipe and tube making process begins with a steel plug, steel slug or billet that is heated to molten temperature and pierced on a piercing mill to initiate the elongated and hollow nature of pipe. The pipe then passes through a stretch reducing mill to further re-size and work the metal. Tube and pipe mills

Minimizing wall thickness variation in seamless tubing

2003-8-28 Five main types of elongator mills are used in the tube producing industry: the mandrel pipe mill, the push bench, the plug mill, the stretch reducing mill, and the cross-rolling elongator mill. Fifty years of industrywide use have shown that, of these elongator mills, the cross-rolling elongator provides the most significant improvement in
