Product Description
RDL-F30 slow tensile stress creeping testing machine corrosive
01 Overview
RDL-F series slow tensile (pre-crack) stress corrosion testing machine
It is mainly used to detect and study the mechanical performance test of metal materials under the dual effects of extremely slow tensile stress and corrosive medium environment. It can also be used to simulate the corrosion resistance of parts under constant tensile stresses in a corrosive environment, conduct a constant load pre-crack stress corrosion test, and detect and study the destructive performance of metal materials under the dual effects of constant tensile stress and corrosive medium environment.
The accelerated stress corrosion susceptibility accelerated test of ductile materials is carried out by applying dynamic strain to the sample, which solves the problem that the stress corrosion cracking cannot be stimulated even if the test period is fully extended under constant load and constant deformation conditions.
02 Advantages&Characteristics
Various combinations can be designed to meet various requirements such as different temperatures, pressures, corrosive media, and different corrosive media circulation rates.
It can realize the crack growth measurement under the corrosive medium environment.
It can be equipped with heating, temperature maintenance and automatic liquid supplement device.
Corrosion medium: NaCl, methanol, N2O4, NH3, H2 S, NaOH, NaNO3 and other aqueous solutions.
Corrosion-resistant material: 316 stainless steel for fixtures and organic glass for corrosion tanks.
The number of clamped samples can be expanded according to requirements.
Stress corrosion- displacement
Stress corrosion-temperaturer
| DoLI EDC Controller | High resolution of 24 bits (1 million yards), which can realize high precision measurement. The test parameters can be set through the manual control box to complete the test independently. It can communicate with the temperature controller and control it to ensure that the test process is not disturbed. The temperature will be raised automatically according to the test, and the test will be carried out automatically when the set ambient temperature is reached. It can automatically calibrate the load measurement system to prevent its temperature drift and ensure the measurement and control accuracy. It can automatically identify different inserted sensors. |
| TMC controller | High resolution of 19 bits (500000 yards), which can realize high precision measurement. The temperature drift of analog signal sampling is small. The external independent screen display manual control box can independently complete basic test functions without computer. Automatic identification plug technology. Verification of 10000 hour creep rupture test. The maximum transmission rate is 5000Hz. Four measuring channels of strain sensor (load cell extensometer) can be configured. Four AB signal measurement channels (encoder, grating ruler) can be configured. |
