Introduction for SSRT and SCC test machine

This slow strain rate (SSRT) cortest corrosion (SCC) testing machine is mainly used for inspection, research of metal material static lasting tensile, creep, stress corrosion and the mechanical property test,etc can be used in NaOH, NO3, H2S, CL solution, methanol, N2O4, NH3, wet air and water, and other media environment of metal stress corrosion damage characteristic test.

This tester is a research of new microcomputer control slow strain rate cortest corrosion test machine by Shanghai Bairoe test instrument co., ltd. The machine uses high precision load sensors, high resolution several mining system in data collection, can make the load, deformation and displacement quantity, time and data processing and display, as well as  load, deformation and displacement automatic high speed closed-loop PID controlled. AEC-1000 measurement and control system chooses SMT components,produced by automatic mounted system production, quality is stable, long-term reliable operation. Test software running on windows platform, the domestic initiative of the test control routing design, high grade 3 operation test data processing model, automatic save test data,  can also be tested after suspend of sudden power off, the test conditions and the test results can be automatic inventory, dynamic display the test data and the test curve, can be printed.

Loading unit is the independent modular servo drive unit, reasonable structure compact, powerful function,flexible installation and configuration, can satisfy various kinds of models for different loading unit to install location demand.

This tester is necessary equipment for steel, aviation, aerospace, petrochemical industry, scientific research institutes, universities and slow strain stress corrosion test for material

1)  Testing standard:

l ASTM G129 - 00(2006) Standard Practice for Slow Strain Rate Testing to Evaluate the Susceptibility of Metallic Materials to Environmentally Assisted Cracking

l ASTM E399 Standard Test Method for Linear-Elastic Plane-Strain Fracture Toughness KIC of Metallic Materials

l HB 7235-1995 Slow Strain Rate Cortest Corrosion Test Standard

l ISO 7539-7-2005 Corrosion of Metals and Alloys – Stress Corrosion Testing Part7: Method for Slow Strain Rate Testing

System Composition: it is composed of stress corrosion loading system, high-temperature autoclave system, water treatment system, crack detection system, test fixture, measurement and control system, test software, computer, printer and other parts.

    2)  Stress corrosion loading system:

Mainly used for slow strain rate stress corrosion testing machine loading, control and data processing, mechanical drive unit, electrical control and drive unit of measurement and control software unit. Mechanical drive unit selection on Taiwan silver precision ball screw, Taiwan and Liyi planet wheel reducer and Japan Yaskawa servo drive unit as a basic drive loading unit, the quality is stable and reliable. Measurement and control unit choose the United States CELTRON load sensor, Shanghai Chunyuan grating displacement sensor and our company developed its own AEC - 1000 control system composition, this system after long-term use of proven, measurement and control high precision, stable performance

Feature:

Event data can be saved, test can continue to be interrupted when the power supply test.The machine Supports more than 20 days of continuous testing.Four specimen can be tensile test at one time.Support for multi-language user-interface extendibility, pre-installed with American English and Simplified Chinese.Dynamic display of load, displacement, deformation and real-time testing curve on the screen.Closed loop control of channels such as load, displacement, deformation, etc. Smooth switching in between.Domestically pioneered open-testing-method settings. Engineers may set up testing projects then operators may employ the projects for testing, greatly reduced the difficulty of the operations and the requirement in the skills and trainings of the operator.Domestically pioneered process-oriented design of testing control. Provides users with intuitive testing control procedures and a wide range of instruction types. Also supports dynamic instruction parameter assignment.Domestically pioneered highly efficient three-level operation model of testing data processing. Supports open testing data processing, appending custom testing data items and re-inspection of processed testing data.Rounding off of numerical testing data complies with GB 8170-87 (UDC511.1/2) Rules of Rounding Off for Numerical Values, supports rounding off in sections and custom rounding off.Characteristic testing data can be marked on testing graphs.Capable of statistical operations on testing data (average, standard deviation, coefficient of variance).Automatic requesting for testing result data, also capable of launching an advanced analysis to inspect the data.As many as 20 layers of sensor linear compensation, elevates the precision of the instruments to the next level.Support saving, instant retrieving and inspection of testing results.Capable of re-analyzing test data and curves, and partial zooming of testing curves at will.Open testing report, support custom testing template, automatic generation of testing report, which can be printed, previewed or saved as files.Integrated with software limit protection, hardware travel limit protection and full scale overload protection.
