See Section 6 for additional safety information. Already Subscribed to this document. The test cell is then automatically vented, purged and cooled further so that the test samples can be safely retrieved.

Most of the information developed using this practice has been obtained for such materials. The test temperature and hydrogen gas pressure are selected to simulate those conditions found in refinery hydrogen-containing environments. These tests can be used to assess the effects of material composition, processing methods, fabrication techniques, and heat treatment as well as the effects of hydrogen partial pressure, service temperature, and cooling rate.

We’ll help you configure a system that meets all of your research needs. Land Use and Development. Historical Version s – view previous versions of standard. This practice is applicable over a broad range of pressures, temperatures, cooling rates, and gaseous hydrogen environments where HID could be a significant problem.

Additionally, this practice does not address the evaluation of high-temperature hydrogen attack in the steel substrate.

Gg146, 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. No other units of measurement are included in this standard.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The control system for the apparatus automatically purges the vessel with argon, performs a high pressure leak test with nitrogen and then sequences the main portion of the test.

E3 Guide for Preparation of Metallographic Specimens. However, due to the broad range astmm 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 apparatus developed by Parr consists of a high pressure, high temperature test cell made from Inconel Additionally, this practice does not address the evaluation of high-temperature hydrogen attack in the steel substrate. The test cell is then automatically vented, purged and cooled further so that the test samples can be safely retrieved. Standards Subsctiption may be the perfect solution. 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.

As the voice of the U.

Two gas booster pumps, one for nitrogen and the other for hydrogen, are used for g1146 the test cell. This system can be used over a broad range of pressures, temperatures, cooling rates, and gaseous hydrogen environments where HID could be a significant problem.

The test temperature and hydrogen gas pressure are selected to simulate those conditions found in refinery hydrogencontaining environments. These tests can be used to assess the effects of material composition, processing methods, asmt techniques, and heat treatment as well as the effects of hydrogen partial pressure, service temperature, and cooling rate.

However, it should be noted that this y146 may not be appropriate for forms of bimetallic construction or service conditions which have not been observed to cause HID in service. Two gas booster pumps, one for nitrogen and the other for hydrogen, are used for pressurizing the test cell. However, y146 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.
