This involves clamping the pipe flat until the flow stops. The <strong>Squeeze-off Tester<\/strong> (Crushing and Flattening Machine) is designed to verify that the pipe can withstand this extreme deformation without cracking, splitting, or suffering long-term structural damage.<\/p>\n<h3>Hydraulic Precision and Stability<\/h3>\n<p>Unlike simple manual clamps, this laboratory device provides controlled, measurable deformation:<\/p>\n<ul>\n<li><strong>Hydraulic Locking System:<\/strong> A key feature that stabilizes the force during the test. This allows the machine to hold the pipe in the &#8220;squeezed&#8221; position for long durations to check for stress cracking (Slow Crack Growth).<\/li>\n<li><strong>Chrome-Plated Guides:<\/strong> The moving plate glides on precision-machined rods, ensuring the compression is perfectly vertical and the pipe is not subjected to uneven shear forces.<\/li>\n<li><strong>Displacement Control:<\/strong> With an accuracy of <strong>0.1 mm<\/strong>, operators can stop the compression exactly at the standard-defined limit stops.<\/li>\n<\/ul>\n<h3>User-Friendly Digital Interface<\/h3>\n<p>The machine is equipped with a <strong>4.3-inch Color Touch Screen<\/strong> that allows operators to:<\/p>\n<ul>\n<li>Set the compression speed.<\/li>\n<li>Monitor real-time force and displacement data.<\/li>\n<li>Lock the hydraulic pressure for extended testing cycles.<\/li>\n<\/ul>\n<h3>Complementary Mechanical Testing<\/h3>\n<p>The squeeze-off test focuses on the pipe&#8217;s ability to deform and recover.
