Typically, longer exposure times at the test conditions must be utilized to allow for the resistance to decarburization, internal blistering or cracking, or both, to be evaluated.

However, it should be noted that this practice may not be appropriate for forms of bimetallic construction or service conditions which have not been observed to cause HID in service. However, due to the broad range of possible materials, test conditions, and variations in test procedures, it is up to the user of this practice to determine the suitability and applicability of these procedures for evaluation of such materials.

The system incorporates an automated back pressure regulator and a variety of automated valves for pressure control. G1466 may delete a document from your Alert Profile at any time.

Link to Active This link will always route to the current Active version of the standard. No other units of measurement are included in this standard. Link to Active This link will always route to the current Active version of the standard. This system can be used over a broad range of pressures, temperatures, cooling rates, and gaseous hydrogen gg146 where HID could be a significant problem. The test cell is then automatically vented, purged and cooled further so that the test samples can be safely retrieved.

The procedures described herein, may also be appropriate for evaluation of hot roll bonded, explosive bonded, or other suitable processes for applying stainless alloys on steel substrates.

Most of the information developed using this practice has been obtained for such materials. However, it should be noted that this practice may not be appropriate for forms of bimetallic construction or service conditions which have not been observed to cause HID in service. The test temperature and hydrogen gas pressure are selected to simulate those conditions found in refinery hydrogen-containing environments.

This practice is applicable over a broad range of pressures, temperatures, cooling rates, and gaseous hydrogen environments where HID could be a wstm problem. This standard is also available to be included in Standards Subscriptions. However, it should be noted that this practice may h146 be appropriate for forms of bimetallic construction or service conditions which have not been observed to cause HID in service.

Standards Subsctiption may be the perfect solution. These tests can be used to assess the effects of material composition, processing methods, fabrication techniques, and heat treatment as well as v146 effects of hydrogen partial pressure, service temperature, and cooling rate.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

The main test consists of filling the test cell with hydrogen, heating the vessel at a user defined temperature set point for a period of typically 48 hours.
