Ground settling or environmental pressures cause bending at the connection points (Joints). The <strong>Leak Tightness Tester under Bending<\/strong> manufactured by <strong>Polymer Test<\/strong> simulates precisely these rigorous conditions to ensure that O-rings and mechanical joints maintain their seal even when curved\/bent.<\/p>\n<h3>Operating Mechanism: Combined Stress Simulation<\/h3>\n<p>This test is one of the most challenging evaluations for fittings as it applies two forces simultaneously:<\/p>\n<ol>\n<li><strong>Internal Pressure:<\/strong> Water is pumped into the pipe at a specific pressure (typically by connecting to our <a href=\"https:\/\/polymertest.com\/en\/product_en\/hydrostatic-pressure-burst-tester-1-to-10-stations\"><strong>Hydrostatic Pressure Tester<\/strong><\/a>).<\/li>\n<li><strong>Bending Force:<\/strong> Simultaneously, the machine&#8217;s powerful motor and gearbox system bend the pipe to a specified radius. If a single drop of water escapes from the joint in this state, the sample fails.<\/li>\n<\/ol>\n<h3>Engineering Features<\/h3>\n<ul>\n<li><strong>Motorized Bending System:<\/strong> Utilizes an electric motor and precision gearbox instead of manual jacks, allowing for the application of uniform and controlled force.<\/li>\n<li><strong>Adjustable Fixtures:<\/strong> Features movable supports that enable testing of a wide range of pipes with different diameters and lengths without the need to change main components.<\/li>\n<li><strong>Versatility:<\/strong> Suitable for testing Polyethylene (PE) pipes, PVC-U pipes, and mechanical compression fittings.<\/li>\n<\/ul>\n<h3>International Standards<\/h3>\n<p>This equipment is designed exactly based on the dimensional and force requirements of the following standards:<\/p>\n<ul>\n<li>International Standard <a href=\"https:\/\/www.iso.org\/standard\/61260.html\" target=\"_blank\" rel=\"nofollow noopener\"><strong>ISO 3503<\/strong><\/a> (Plastics piping systems \u2014 Mechanical joints between fittings and pressure pipes \u2014 Test method for leaktightness under internal pressure of assemblies subjected to bending).<\/li>\n<li>National Standard <strong>INSO 13502<\/strong>.<\/li>\n<\/ul>\n<p>For price inquiries and technical consultation regarding the machine&#8217;s capacity, please click the contact for purchase button or visit our <a href=\"https:\/\/polymertest.com\/en\/contact-us\/\"><strong>contact us<\/strong><\/a> page.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The PolymerTest Leak Tightness Tester simulates real-world stress on pipe joints caused by ground settling.
