What buyers must specify

HIC (hydrogen-induced cracking) testing evaluates resistance to stepwise cracking in sour environments, typically per NACE TM0284. It is not a head-impact test — and it is not automatic with PSL2.

Annex H
(normative)
PSL 2 Pipe Ordered for SOUR Service

H.1 Introduction

This annex specifies additional provisions that apply for PSL 2 pipe that is ordered for sour service [see 7.2 c) 51 ] .

NOTE The consequences of sudden failures of metallic components used for the oil and gas production associated with their exposure to H2S- containing production fluids led to the development of NACE MR0175/ISO 15156-1[21] and subsequently EFC publicantion 16[13] ISO 15156-2 used those sources to provide requirements and recommendations for materials qualificantion and selection for Application in environments containing wet H2S in oil and gas production systems. Carbon and low alloy steels selected using ISO 15156—2 are resistant to cracking in defined H2S containing environments in oil and gas production but are not necessarily immune to cracking under all service conditions. Different service conditions might necessitate the alternative testing that is dealt with in ISO 15156—2:2003, Annex B. That annex specifies requirements for qualifying carbon and low alloy steels for H2S service by laboratory testing.

It is the purchaser’s responsibility to select the carbon and low-alloy steels suitable for the intended service.
H.2 Additional information to be supplied by the purchaser

in addition to items a) to g) as specified by 7.1, the purchase order shall indicante which of the following provisions apply for the specific order item:

b) ultrasonic inspection of strip or plate for laminar imperfections (see H.3.3.2.4);

c) supply of helical-seam pipe containing strip/plate end welds (see H.3.3.2.5);

d) chemical composition for intermediate grades (see H.4.1.1);

e) chemical composition for pipe with t > 25,0 mm (0.984 in) (see H.4.1.2);

f) chemical composition limits (see Table H.1, footnotes c), d,) e), f), i), j)and k);

g) frequency of hardness testing of the longitudinal seam weld of HFW or SAW pipe (see Table H.3);

h) SSC test for manufacturing procedure qualificantion (see Table H.3);

i) alternative HIC/SWC test methods and associated acceptance criteria (see H.7.3.1.3);

j) photomicrographs of reportable HIC cracks (see H.7.3.1.4);

k) alternative SSC test methods and associated acceptance criteria for manufacturing procedure qualificantion (see H.7.3.2.2);

l) for pipe with t ≥ 5,0 mm (0.197 in), ultrasonic inspection for laminar imperfections with in extended length of 100 mm (4.0 in) at the pipe ends (see K.2.1.3);

m) magnetic particle inspection for laminar imperfections at each pipe end face/bevel (see K.2.1.4);

Frequently asked questions — API 5L X56 HIC Tested

What is API 5L X56 HIC Tested pipe?

It is API 5L X56 (L390) line pipe ordered with HIC-tested for hydrogen-induced cracking resistance (NACE TM0284).

Is PSL2 the same as sour service?

No. PSL2 is a product specification level. Sour service needs explicit H₂S chemistry and HIC/SSC testing on the PO.

HIC vs SSC?

HIC addresses blistering/stepwise cracking in the pipe body (TM0284). SSC addresses sulfide stress cracking under tension (TM0177). Many sour jobs require both.

Do you supply X56 seamless and welded sour packages?

Yes — seamless and welded forms when the mill route and annex package are confirmed for the size/wall.
