HTC-30A High Temperature Stress Rupture and Creep Testing Machine,
Lever Arm Load System
- This type of machine is designed as low cost solutions for
long-term creep and stress-rupture testing applications of metallic
and alloy materials under high temperature in accordance with ASTM,
BS, EN, ISO and other similar international testing standards.
Features:
- The lever arm type machine has been specifically designed for
long-time Creep and Stress Rupture test applications that involve
maintaining constant loads for extended periods of
time.
- Through the mechanical advantage of the lever arm loading system,
constant loads may be maintained with a high degree of accuracy for
long durations, using dead weights, without the continuous
operation and dependency of a mechanically powered drive.
- The lever arm Creep and Stress Rupture machines are an economical
alternative to traditional electro-mechanical or hydraulically
loading universal testing machines which have higher initial
purchase prices and greater long term operating costs. This model
may be configured for either room temperature or elevated
temperature operation. A variety of temperature rated test fixtures
and extension measurement device for the measurement of elongation
on creep test applications are also available.
- Motorized draw-head assembly automatically compensates for specimen
elongation and keeps loading bar with excellent load accuracy of
+/- 0.5% guaranteed.
- Both room temperature and elevated temperature systems are
available
- Furnace and chambers available with temperature ranges from 200°C
to 1100°Cin common air environments
- Numerous high temperature pull rods, specimen holders, furnace
systems and extensometers available for creep and stress Relaxation
applications. Many of which are also adaptable to hot tensile
testing applications on universal testing machines.
- Control system owns the three closed control function as load
control, extension control, and velocity control. High precise
control and accurate load with load measurement resolution reach
1/300000; the loading testing curve can be plotted automatically.
- Additionally, manual operation also be offered, users can unload to
protect the apparatus by hand, especial the load cell, when
suddenly power cut off.
- Software owns powerful function offering specimens registration,
apparatus control, test data acquisition and store, test result
inquiring, data processing and test report export
- Remote communication control function saves your operators
invigilation during testing process; alarm message can be
transmitted to your mobile phone to inform you test situation by
equipping with special dial number device.
