Hydrogen Test Systems


Designed to allow Hydrogen Studies to be safely conducted inside laboratories. These enclosures are equipped with ATEX Certified Ventilation Fans and an Automated Valve Panel in order to declassify the area for use with Autoclave Systems, Load Frames, and DCPD Testing Equipment.


Load Frames

Designed for Slow Strain Rate Testing (SSRT), Constant Extension Rate Testing (CERT), Corrosion Fatigue Testing (CF), and other custom applications requiring mechanical loading. These systems use pull-through rod systems that allow them to use Autoclaves, Tempressure Vessels, or Ambient Condition Test Chambers to simulate corrosive field conditions in High Temperature High Pressure (HPHT) environments.


Proof Rings

The most widely used equipment for evaluating sulfide stress cracking and stress corrosion cracking behaviors of materials. The compact size, accuracy, and ease of use provides an economical means for testing multiple specimens simultaneously in a fume hood. Cortest Proof Rings were our original product in 1977 – they meet the testing requirements of NACE TM 0177 test method which is used to determine materials that meet the NACE material requirement of MR 0175.



DCPD & Fatigue Testing

Direct Current Potential Drop (DCPD) testing is a widely accepted method for measuring crack growth or conducting crack initiation testing by applying electrical current to a specimen and measuring electric potential across the crack plane.



HPHT Circulating Flow Loop Systems

High Temperature, High Pressure  (HPHT) Circulating Flow Loops are used to test materials in high purity water environments. These systems can create supercritical and multiphase conditions such as those seen in Pressurized Water Reactors (PWR) and Boiling Water Reactors (BWR). Our HPHT Circulating Flow Loops include a pumping system, heaters, heat exchangers, filters, thermocouples, and equipment for measuring water conditions including dissolved oxygen, dissolved hydrogen, pH, and conductivity.
