Mechanical stretch is a simple process by which the fabric is woven to a wider width and in the finishing, the fabric is shrunk creating a stretch when pulled. These are fabrics that utilize their memory and bounce back to their original state.

The invention relates to a method for performing an expansion test of combined loads on a solid expansion pipe, which comprises the following steps of: 1) preparing a sample and an expansion cone; 2) expanding an end part; 3) preparing an expansion test; 4) performing the expansion test, wherein the expansion test can be any one of the following tests: a, a mechanical stretching expansion test; b, a hydraulic expansion test; and c, a mechanical hydraulic combined expansion test; and 5) performing data acquisition and data analysis. In the method, the mechanical stretching expansion test or the hydraulic expansion test or the combined expansion test of mechanical stretching and hydraulic pressure is realized, and the displacement, speed, stretching loads and hydraulic pressure of the expansion cone and the radial deformation data of the solid expansion pipe in the process of the expansion test can be measured in real time by using axial controlled mechanical stretching loads and the hydraulic pressure and matching the corresponding expansion conical head. The invention provides a method for the expansion test for simulating actual working conditions in laboratories effectively for the detection of expansion performance and study evaluation of the solid expansion pipe and the study and improvement of a connecting structure of the expansion pipe.
