Description

Hydrogen disbonding test is done to evaluate the disbonding of bimetallic stainless alloy-steel late for use in refinery high-pressure/temperature gaseous hydrogen service. This method provides as indication of the resistance or susceptibility or both to HID.

This practice is applicable over a broad range of pressures, temperatures, cooling rates and gaseous hydrogen envitonments where HID could be significant problem.

This test can be used to asses the effects of material composition, processing methods, fabrication techniques and heat treatment as well as the effect of hydrogen partial pressure, service temperature and cooling rate.

For the HID test, we are equipped with an autoclave with following details :
Capacity : 2 ltr
Working Temperature : 525 deg C
Working pressure : 200 bar
