Introduction of API 5L X56 HIC Tested Pipe

The HIC test actually evaluates steel in terms of its susceptibility to hydrogen embrittlement. The test procedure involves evaluating the resistance of pressure vessel steel plates and pipeline steels to hydrogen reduction cracking caused by hydrogen uptake by sulfide water corrosion.

American Petroleum Institute 5L specification Covers Seamless and Welded Steel Line Pipe. It includes standard-weight and Extra-Strong threaded Line Pipe. It includes standard-weight and extra-strong threaded line pipe; and standard-weight plain-end, regular-weight plain-end, special plain-end, extra-strong plain-end, special plain-end, extra-strong plain-end pipe; as as well as bell and spigot and through-the-flow line(TFL) pipe. API 5L Line Pipe is dimensionally equivalent to A106 and A53 pipe, conforming to industry standard sizes, however it performs to different mechanical properties. One key defining characteristic of this pipe is its yield strength, where the two digit number following the pipe’s "X" grade indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade Hastelloy C276(i.e. X52 Pipe)

API 5L X56 HIC Tested Pipe for sour oil and gas containing Hydrogen Sulfide (H2S) generally suffer from either Hydrogen Induced Cracking (HIC) or sulfide stress corrosion cracking (SSC). Oil and gas containing high H2S are noxious to pipeline steels because of the hydrogen-induced corrosion [1]. In recent years, driven by energy considerations, oil and gas reserves have been discovered under in deep waters, where the environment is more aggressive [2]. This gives rise to a demand for high-quality, special, microalloyed steels to make pipes having a good resistance to the environment at the stages of exploitation and transport of these products. Therefore, it is necessary to develop new steels in order to meet the rigorous corrosion requirements such as H2S corrosion. It is well known that high-strengthgrade steel pipelines have to offer at least three benefits, including safety, economy and efficiency, during supplying their products to market. In addition, higher-strength-grade steels can avoid large wall thickness under in deep waters, which facilitates the pipe making process. So it is essential to develop high-strength pipeline steels with better H2S resistance. However, it is very difficult to enhance the strength level of the pipeline steel but with no decrease in the H2S resistance. This is a great challenge in the current research of pipeline steel. In the last two decades, much work concerning the effects of composition, microstructure and inclusions on H2S resistance has been done

The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries Grades covered by this specification are A25 ,A ,B (and the following "X" Grades) X42, X46, X52, X60, X65, & X70 The two digit number following the "X" indicates the Minimum Yield Strength (in 000's psi) of pipe produced to this grade.

Hydrogen-Induced Cracking

HIC testing was performed according to NACE standard TM 0284-2003. The sample was 100 mm long, 20 mm wide, and had the same thickness as the plate. Figure 1 shows the sample orientation And the face that will be examined after the test. The HIC test was performed in a solution of 5.0 wt% NaCl, 0.50 wt% CH3COOH and 94.5 wt% distilled water at ambient temperature and normal pressure, and the duration was set at 96 and 288 h. Pure nitrogen gas (N2)

Specimen Size

  • To conduct the HIC test, requires the following sample sizes:
  • Pipe - upto 2" OD - 200mm long
  • If the pipe is more than 2" OD pipe - 100mm long sample size is required
  • Number of pieces to be tested upto 88mm thick/dia - set of 3 pieces to be tested
  • Number of pieces to be tested more than 88mm thick/dia - 5 pieces to be tested

NACE TM0284 Test Solution

NACE TM0284 specifies either Solution A or Solution B. Solution A is acidified brine. Solution B is simulated seawater prepared in accordance with ASTM D1141.52. In either case, H2S is bubbled through the solution constantly throughout the test period. NACE TM0284 specifies test duration of 96 hours.

Detailed Report

A detailed written report upon completion of each test. Each report includes a description of the test sample that was received, the test procedure that was used, and the pH values of the test solution before exposure and after the exposure. The test bars are cut into sections and examined under a microscope for hydrogen-induced cracks. The dimensions of any such cracks are recorded and used to compute the values in percentage for Crack Length Ratio (CLR), Crack Thickness Ratio (CTR) and Crack Sensitivity Ratio (CSR).

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 publication 16[13] ISO 15156-2 used those sources to provide requirements and recommendations for materials qualification 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

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.4.4 Hardness test

For test pieces subjected to a hardness test (see H.7.3), the hardness in the pipe body, the weld and HAZ shall be ≤ 250 HV10 or 22 HRC (70,6 HR 15N).

The maximum acceptabie hareness of an unexposed weld cap and external surface HAZ and base metal may be 275 HV10 or 26 HRC (73,0 HR 15N) where the equipment user agrees to the alternative weld cap hardness limit, the parent pipe wall thickness is greater than 9 mm, the weld cap is not exposed directly to the sour environment and the escape of hydrogen is not impeded, e.g by cathodic protection.
