Suggest you examine the failures to see what the HIC damage is associated, i.e. is it sulphide inclusions, or microstructural variation, these will influence the test result.
The level of residual stress you have imparted into the item in forming plate to pipe will also have a detrimental effect on the HIC resistance of the material.
