The increased growth in the development and use of plastic pipes for oil pipelines, gas and water distribution, and ducting for telephone and electrical cables, etc. has created a need for a vast range of mechanical testing to make sure that the product employed is most suitable for its particular function and at the same time can survive all the stresses caused by extreme temperature fluctuations and underground land shifts.
Testometric provides a complete test system for carrying out the specialized tests necessary for assessing such products.

Grips
Testometric offers an extensive range of grips for performing compression tests on pipes up to 1600 mm diameter, tensile tests on thick wall and thin wall pipes, hook tensile tests, peel on multi layer pipe and so on.
Extensometry
Various custom built extensometers are available that can function on thick- or thin–walled pipe sections.
Software
Testometric also provides an extensive pipe test software with pre-defined calculations to international standards. They include tensile strength, tensile ring strength, ring stiffness, hook strength, creep/crack detection, peel strength, and long term prediction values.
