Zwick’s ProLine and Allround testing machine ranges cover the entire force range for testing all common pipe diameters. The load frames can be equipped with two test areas; for example the upper test area can be used for tensile tests on shouldered bars and the lower test area for compression tests to determine stiffness or ring flexibility. Load frames with two test areas are efficient and highly operator-friendly as they eliminate tool changing.
 
Test-sequence control by testXpert^® Standard Test Programs makes testing simple and reliable. All the principal test results are pre-programmed and are calculated automatically.
 
Many types of pipe require deformation measurement on the inner diameter.  A special long-stroke extensometer is available from Zwick for this, together with a manual extensometer specifically developed for pipe testing.
