Production of steel sleeve repeated tensile and compressive testing machine

The microcomputer controlled steel sleeve grouting connection repeated tensile and compressive testing machine mainly performs tensile, compressive, bi-directional tensile and compressive, fatigue, low cycle fatigue, crack propagation, fracture mechanics, and various metric and imperial prestressed steel strands testing on steel mechanical connection joints based on the provisions of standards such as JGJ163-2015, JGJ107-2016, JGJ335-2015, and 2019 Technical Specification for Steel Mechanical Connection.
