With one of the largest non-mill inventories in the U.S.A., stocked in six service centers, we have what your project requires. As an added service, all of our facilities maintain pro-cessing capabilities in-house. Whether you need material punched, flame cut, plasma. Hence if both chlorides and H2S are encountered in oil & gas production, oRen nickel base alloy like alloy must be used. Alloy 31 (UNS N) is a high alloyed stainless steel .
STANDARD MATERIAL SPECIFICATIONS Réf. Rév. Page IN 2 1/19 AC This document contains confidential proprietary material belonging to Axens which may only be made available. Introductions to the seven sections discuss the evolution of technology in each of these areas: wet H2S cracking in refinery service, wet H2S cracking in oil and gas production and pipelines, sulfide stress cracking/hydrogen embrittlement cracking in high-strength steels, environmental and metallurgical factors in hydrogen-induced cracking.
Carbon steel and stainless steel of the type 18% Cr–10% Ni () find place in electrochemical plants, as well as in other plants of the chemical and metallurgical industries, as major structural materials. As noted in Chapter 1, in neutral media, carbon steel has an active state and corrodes, with oxygen depolarization.

Many petrochemical refineries have Hydrogen Sulphide (H2S) present in the their process streams. Famous for it’s smell of rotten eggs H2S when mixed with liquid water in a refinery is known as Wet H2S.
In most refineries carbon steel boiler plates are used in this environment but they are subject to degradation depending on the a number of key factors. Wet Hydrogen Sulfide (H 2 S) Damage is a common problem in the oil & gas and petrochemical/chemical manufacturing industries. It can occur when carbon-steel equipment becomes exposed to wet H 2 S service environments, and it can come in several different forms.
Wet H 2 S corrosion can be a particularly dangerous form of corrosion because damage caused by it takes place on the interior of. Steel 1B was calcium treated (%), and had a very low carbon content (%).
Steel 1B was an X65 grade pipe, similar to the preceding pipe steels, with the exception that it did not contain a detectable level of Nb. It was calcium treated (%). The pipeline material, 1B was selected because of its high sulphur content (0.

The result shows that in the heavy wet H2S corrosion environment was formed by lots of sulfide accumulated in the equipment,the heavy corrosion of OCC, HB, HIC, SCC occurred in the carbon steel.
This document summarises existing knowledge and recommended practices for the specification, design, manufacture, inspection and repair of carbon steel equipment in wet H2S service. Most types of carbon steel equipment are within its scope, both new and used.
However, some of the damage mechanisms associated with wet H2S exposure are. Exposure of carbon-steel equipment to wet H 2 S service environments can lead to various forms of attack, e.g. hydrogen blistering and hydrogen induced cracking (HIC), stress oriented hydrogen induced cracking (SOHIC) and sulfide stress cracking (SSC).
Documenting equipment have been attributed oo these forms of corrosive damage. This large scale test program, sponsored by the. Now consider evaluation of carbon and low alloy steels for their resistance to HIC/SWC. The designers must evaluate the flat-rolled carbon steel products for sour service environments containing even trace amounts of H2S material for HIC/SWC.
The possibility of HIC/SWC is influenced by chemistry and manufacturing route of steel. Materials for sour gas H2S Sour gas at high pressure, temperature and in mixtures of other acids like formic acids found typically indown hole oil well stimulation environments is extremely corrosive.
In these environments few materials could survive. Tantalum surface alloys are immune to sour gas environments showing no measurable corrosion rate.
This far exceeds the performance of. hi several problems occur in CO2/H2S/H2O environments: generalized corrosion (loss of metal thickness) of carbon steel materials due to - pH lowered by dissolution of acid gas CO2 and H2S - and to scaling properties of the formed iron carbonate / sulfur scales.
it exists models that describe with more or less success the corrosion rates in CO2/H2S/H2O environments: Dewaard / Nesic /. The produced crude oil from reservoir contains water and also different undesirable by- products called "Acid Gases". Acid Gasses refer to H2S (Hydrogen Sulphide) and CO2 (Carbon.
Sour service, or wet hydrogen sulphide (H2S), environments are commonly encountered in the petrochemical industry. The corrosion of steel under these conditions generates hydrogen, which when absorbed by the steel can lead to crack development and eventual failure in pipelines, pressure vessels, and related plant equipment.

2 corrosion rates under wet conditions. Rates may vary from mm/yr to 18mm/yr depending on circumstances. Thus given that some parts of CCS processes, for example inlets to absorbers and coolers/knock out vessels in CO 2 compression systems are exposed to wet CO 2 conditions, it is clear that alternatives to carbon steel are needed in some.
Paper presented at Corrosion San Antonio, Texas, USA, March Abstract. To address the widely held concern that ISO/NACE MR limits for sour service cracking resistance of Type /L stainless steel in oil & gas production environments were excessively conservative, a program of laboratory studies was undertaken testing parent materials in compliance with the ballot.
13 Cr (Martensitic Stainless Steel) Figure 1 represents the generally acceptable regions of performance for 13 Cr stainless steel exposed to wet CO 2 containing NaCl. This figure is only applicable in the absence of oxygen and hydrogen sulphide (H 2S). Small amounts of oxygen can cause severe pitting of 13 Cr in the presence of chlorides.
CLEARANCE!. This publication brings together a broad range of published papers specifically addressing cracking of steels and weldments resulting from absorbed hydrogen when exposed to wet H2S environments. It includes 72 classic papers from NACE and other sources covering published literature from to Other non-NACE sources include books published by the American Petroleum.

I've been unable to find material discussing the performance of low-alloy steels in wet H2S service with respect to blistering, HIC/SOHIC, etc.
