H₂S, CO₂ medium slow strain rate stress corrosion testing machine

Equipment brief description:
This equipment is used in the petrochemical industry to test the corrosion resistance of materials in H2S and CO2 medium environments.
The equipment consists of a load-bearing frame, a loading unit, a control system, an experimental kettle, a heating system, a gas loop system, a DCPD crack growth measurement system, test software, a gas detector, etc.
The experimental kettle and high-temperature furnace can be lifted and lowered electrically to facilitate the installation of specimens.The gas loop system realizes the injection and pressurization of H2S, CO2, and Ar, as well as the addition and recovery of solutions, etc.The pressure balance device eliminates the additional attachment force exerted on the specimen by the pressure in the kettle.The experimental kettle lid has reserved mounting holes, which can be connected to interfaces such as gas injection, solution injection, solution discharge, temperature measurement, and DCPD measurement.
H2S and CO2 gas detectors are used for leak detection, and their output action ports can be connected to the sewage system.For H2S media, safety facilities such as recovery pools, sprays, and exhaust must be considered.
The DCPD system realizes crack preset, fatigue crack measurement, corrosion crack measurement, constant K test, rising K test, falling K test, and crack expansion rate measurement of CT specimens in corrosive medium environment.
Experimental features:
Ordinary tensile test.
Constant load creep/stress corrosion testing.
Slow strain rate tensile testing.
Low cycle fatigue/corrosion fatigue testing.
Test for measuring crack initiation and crack propagation rate of specimens.
Constant K control, rising K control, and falling K control tests.
Features:
Dynamic display: Load, displacement, deformation, time and test curves are dynamically displayed on the screen in real time.
Record and output stress-strain, force-time, force-displacement and other test data and curves.
Supports long-term continuous testing.
The test control is streamlined and the test process conditions can be compiled by oneself.
Automatic protection: Automatic protection and memory when force value reaches, time limit, breakage, etc. occur.
Automatic data processing: The test software automatically processes data according to corresponding standards.
Data is saved at any time and retained when power is turned off.
The test results can be stored and can be read and consulted at any time.
Test data and curves can be reanalyzed, and curves can be enlarged arbitrarily.
The open test report supports customized report templates, automatically generates test reports, can be printed or previewed, and can be saved as a file.
It has software limit protection, stroke limit protection, and full-scale overload protection functions.
Equipment features:
High rigidity heavy load frame.
High-performance fully digital servo loading control system with high speed control accuracy.
Using grating displacement sensor, the sample deformation measurement accuracy is high.
Integrated measurement and control system facilitates expansion and use.
Realize crack growth measurement in corrosive media environment.
