Pipe tension and compression testing machine

Shandong Huayan's microcomputer controlled pipe tensile and compression testing machine has the characteristics of compact structure, simple and easy to use, etc. It can be used for force measurement tests such as tension, compression, bending, shearing, peeling, and tearing with a maximum load of 300 kN, and meets the room temperature tensile method for pipe specimens in GBT228.1-2021.

The main machine adopts high-precision ball screw loading, which has high rigidity and good linear motion characteristics.Optional load sensors with different ranges can provide accurate measurement data for samples as small as micron-level fibers and as large as fully loaded structural parts.In addition, a wide range of fixtures, deformation measurement and other accessories enable mechanical testing of different materials and samples.

The control method adopts microcomputer control and uses special Test software. This measurement and control software can be used for electronic universal testing machines to conduct various metal and non-metal tests, and complete various functions such as real-time measurement and display, data processing, and result output according to corresponding standards.It can display various indicators such as force value, displacement, deformation, speed, etc. at the same time, and realize real-time screen display of various test curves such as force-deformation, force-displacement, etc. It can switch observation at any time and zoom in and out of the curve. It is very convenient and can display dynamic curves in real time.
