Constant-Load Creep Testing System
Reliable Long-Term Creep and Stress-Rupture Testing Under Elevated Temperatures
Creep is the time-dependent deformation of materials subjected to sustained loading at elevated temperatures. Understanding creep behavior is critical for components operating in power generation, petrochemical, aerospace, process industries, and other high-temperature applications where long-term dimensional stability and structural integrity are required.
The ITC Series Constant-Load Creep Testing Systems are designed to perform creep and stress-rupture testing under precisely controlled loading and temperature conditions. Developed based on proven dead-weight lever-arm principles, the ITC platform combines mechanical simplicity, long-term stability, and low operational cost with modern instrumentation and monitoring capabilities.
Why Constant-Load Dead-Weight Systems?
Unlike electromechanical or servo-controlled testing machines, dead-weight lever-arm systems apply load through gravity rather than active control algorithms.
This approach offers several advantages for long-duration creep testing:
-
True constant-load application without control-loop induced load fluctuations.
-
Exceptional long-term stability during tests lasting thousands of hours.
-
Reduced maintenance requirements due to the predominantly mechanical architecture.
-
Lower operational costs compared to continuously controlled electromechanical systems.
-
Simplified operation and high reliability in research and industrial laboratories.
Because the applied load originates from calibrated dead weights and lever geometry, the loading condition remains inherently stable and independent of controller tuning parameters.
ITC Platform Overview
The ITC platform has been developed for elevated-temperature creep and stress-rupture testing of metallic materials and welded joints.
The platform is designed around a constant-load lever-arm architecture with a nominal capacity of 35 kN and a lever ratio of 1:15.
High-temperature capability is typically provided through resistance furnaces operating up to 1200°C, with optional configurations available up to 1400°C.
Load-train components are manufactured from carefully selected high-performance alloys suitable for the temperature and stress levels encountered during long-term testing.
ITC-A
The ITC-A configuration represents the standard laboratory platform.
Load is applied through the dead-weight lever system and monitored through calibrated loading arrangements. Temperature is measured using thermocouples and external temperature indicators. Lever-arm position adjustment and temperature control are performed manually by the operator.
The ITC-A platform provides a robust, reliable, and cost-effective solution for routine creep and stress-rupture testing.
ITC-B
The ITC-B configuration introduces integrated digital monitoring capabilities.
In addition to the standard ITC-A architecture, the system incorporates load-cell-based load monitoring and unified operator interfaces allowing simultaneous observation of load and temperature data.
Temperature setting and lever-arm position adjustments remain operator-controlled while monitoring and data visibility are significantly enhanced.
ITC-C
The ITC-C configuration represents the most advanced version of the platform.
A continuous lever-position sensing system monitors the arm angle in real time. Position data are processed by an onboard controller which automatically actuates a motorized compensation mechanism connected to the specimen load train.
This arrangement continuously maintains the desired lever position throughout the test, eliminating routine manual adjustment requirements and improving long-term operational autonomy.
The ITC-C platform is particularly suited for extended-duration tests requiring minimal operator intervention.
Modular Architecture
The ITC platform is designed as a modular system and can be configured according to laboratory requirements.
Available options include:
-
Multi-station configurations for simultaneous testing of multiple specimens
-
Extended temperature capability up to 1400°C
-
Integrated data acquisition systems
-
Advanced displacement measurement systems
-
Custom specimen geometries
-
Specialized high-temperature load-train designs
-
Laboratory information system integration
Whether deployed as a single-station research unit or a multi-station industrial creep laboratory, the ITC platform provides a reliable and scalable solution for long-term elevated-temperature testing applications.
