In the images we show, for example, we can see a plant built by PTC for an Italian company that supplied the entire production system to a pipe manufacturer, in two twin units destined for a plant in Thailand, and another industrial site in China.<\/p>\n<\/div><div class=\"fusion-text fusion-text-6\"><p>But how do you extract the spindle?<\/p>\n<p>When the construction is complete, the pipe is connected to clamps and the pumps of the water blasting unit are activated to push the <strong>pressurized water inside the pipe<\/strong>. Initially, the flow of water struggles to get out because the mandrel acts as a plug, but in a few moments and without effort it manages to <strong>create a cushion<\/strong> between the mandrel inside the pipe and the internal surface of the pipe itself, thus making its way throughout the length of the tube, until it comes out of the end of the coil.<\/p>\n<p>Once out, the thrust of the water produces a <strong>mechanical force<\/strong> that causes the spindle to come out of the terminal end.<\/p>\n<\/div><style type=\"text\/css\"><\/style><div class=\"fusion-title title

flushed with the pumped water, the pressure drops and a <strong>pressure test<\/strong> is carried out to check that the pipe complies with the required specifications.<\/p>\n<\/div><div class=\"fusion-text fusion-text-9\"><p>Once the spindle is set aside, the pipe is connected in a <strong>closed circuit<\/strong>, the pumps are set up to pressurize the pipe up to the established
