By Edward B. Clark, W.E. Amend

This advisor describes an entire technique for accomplishing box hardness trying out to estimate the yield energy of pipeline steels. the method is non-destructive so it really is compatible for in-situ checking out on working pipelines, at pipe garage amenities, or a variety of different destinations. It additionally permits technique diversifications which are compatible for software in numerous occasions and prerequisites that could be encountered on a pipeline right-of-way and in other places. box hardness checking out isn't a 'one measurement matches all' technique the place a unmarried hardness checking out technique is acceptable for software in all events that may be encountered

65. 5 Additional Considerations In addition to determining the sample size estimates and determining the minimum estimated hardness for the population being sampled, additional sampling-related criteria exist that must be considered. The sample size determined applies to each homogeneous lot (uniform attributes) of pipe in the population identified by the pre-assessment process. In the event a small lot of pipe is identified that is less than the required sample size, then each pipe length must be subjected to testing.

The unit would then be mounted on the bare pipe surface. If the hardness tester result was within the specified test block range when the device was attached to the pipe, it would indicate that the proposed tester was not being adversely affected by the existing external conditions. 5 Coupling paste provided with Leeb rebound hardness testers or heavy grease are suitable. org/about-asme/terms-of-use Figure 4. Hardness Test Evaluation Block (not to scale) One other consideration with respect to Leeb rebound testers has been the affect of internal pressure.

All hardness testing standards do not provide such limits. Therefore, it is recommended that other types of testers, particularly those including essential electronic components, should comply with the 4 gauss maximum limit. Others, such as the direct Rockwell testers, would not likely be affected unless significant remnant magnetic fields exist. It is recommended that the pipe remnant magnetism should be checked with a gauss meter prior to conducting hardness testing. org/about-asme/terms-of-use If high remnant magnetic fields are found, then the area should be sufficiently degaussed prior to field testing.
