HIC Test (API 5L 44th ED)
HIC Test (API 5L 44th ED)
(OP)
Hi,
Any know about this HIC test and SCC test for sour service?
Stated in latest API 5L, frequency of HIC test is "One test for each of the first three heats applied; thereafter, one test for each test unit of not more than ten heats of steel"
Does anyone know what it means by heat apply? Are they referring to per batch of the pipe or what.
Thanks. Appreciated.

Can you please elaborate more? Does it mean a certain batch of steel plate made or line pipe. As we know the plate is made first and then plate are used to round into pipe and welded.
So this 'heat' means the batch from the plate or pipe.
Thanks
RE: HIC Test (API 5L 44th ED)
With that understanding, I would interpret your quote to mean that the first three heats applied to a production run had to have the H2S tests performed. After those three heats, H2S tests are to be performed at the normal testing frequency, with the additional requirement that no more than 10 heats be processed in between routine production tests. I have not, however, read the specification you are referring to and would need to read it to be sure that this understanding is correct.
If I were you, and I could not understand the intent of the API specification, I think I'd either call
1) a line pipe manufacturer
2) a testing lab that performs the H2S test in question, or
3) API
One, or all, of these should be able to give you a clear answer.

Yes, you are correct.
The first 3 heats of steel must be tested and subsequently one heat out of 10.
