For the purposes of this document, corrosion includes general andlocalized corrosion mechanisms, as well as environmental cracking mechanismsincluding, but not limited to, stress corrosion cracking (SCC), sulfide stress cracking(SSC), hydrogen induced cracking (HIC) and stress-oriented hydrogen induced cracking(SOHIC).Corrosion-critical: piping systems whose failure could present a hazard to humans orto the environment, or where such failure cannot be repaired without disruptingoperation. Piping systems in hydrocarbon, hydrocarbon processing, flare, and firewaterservice are considered corrosion-critical. Piping systems in other services may bedefined as corrosion-critical by the operating organization with the concurrence ofCSD/ME&CCD.Corrosion Loop: A term to define equipment and piping grouped together that aresimilar in their process environment, made of like material and are susceptible to thesame damage mechanisms.Environmental Cracking: brittle fracture of a normally ductile material in which thecorrosive effect of the environment is a causative factor.EPC: Engineering, Procurement and Construction contractor.Erosion-corrosion: conjoint action of erosion and corrosion in a flowing single ormultiphase corrosive fluid leading to the accelerated loss of material. This phenomenonPage 8 of 46

Also called Intelligent or Instrument Scraping.In-Line Inspection Tool: device or vehicle that is designed to travel through a pipelineand survey the condition of the pipeline wall using nondestructive examination (NDE)techniques. Also known as Intelligent or Instrument Scraper.Microbiologically Influenced Corrosion (MIC): refers to corrosion mechanismsattributed to microorganisms and their by-products.Pipelines: include cross-country and offshore transportation lines, flowlines,trunklines, tie-lines, water supply and injection lines and pipeline branches such asjump-overs. SAES-L-100 defines some of these types of pipelines.Piping: includes pipelines, plant piping, and wellhead piping.Plant piping: includes above and below-ground piping inside a plant area, as definedin SAES-L-100.Plant: includes, but is not limited to, gas oil separation plants (GOSPs), water injectionplants (WIPs), water treatment plants, gas processing plants, fractionation plants,refinery, marine or aviation terminals, bulk plants, power plants, tank farms, andpipeline pump stations.Polythionic Acid Stress Corrosion Cracking (PASCC): a form of stress corrosioncracking normally occurring due to sulfur acids forming from sulfide scale, air andmoisture acting on sensitized austenitic stainless steels.RSA: Responsible Standardization Agent.Sensitization: refers to the composition-time-temperature dependent formation ofchromium carbide in the grain boundaries of austenitic stainless steels and some Nialloys; occurs in the 750 F to 1500 F (400 C to 815 C) temperature range.Stress Corrosion Cracking (SCC): cracking of a metal produced by the combinedaction of corrosion and tensile stress (residual or applied).Stress-Oriented Hydrogen Induced Cracking (SOHIC): is a rare through-thickness typeof environmental cracking where a staggered array of small cracks forms, with the arrayPage 9 of 46

Document Responsibility: Materials and Corrosion Control Standards CommitteeSAES-L-133Issue Date: 23 January 2012Corrosion Protection RequirementsNext Planned Update: 18 July 2014for Pipelines, Piping and Process Equipmentapproximately perpendicular to the principal stress. SOHIC occurs in severe wet, sourservice and can occur in carbon steel pipe and plate that is resistant to HIC and SSC.Sulfide Stress Cracking (SSC): brittle failure by cracking under the combined action ofsusceptible microstructure, tensile stress and corrosion in the presence of water andhydrogen sulfide.Wellhead Piping: is the piping between the wellhead wing valve and the plot limitvalve of a single or multiple well drilling site or offshore production platform.See SAES-L-410.5Minimum Mandatory Requirements5.1Use the corrosion-control measures mandated by this standard for all piping andpressure-retaining equipment exposed either internally or externally to one ormore of the conditions described in Sections 6.1, 6.2, or 6.3 of this standard. Inaddition to this standard, consult SAES-L-132 for environment-specificmaterials selection and SAES-L-136 for carbon steel pipe-type selections andrestrictions.5.2For piping systems that are not corrosion-critical, follow the requirements in thepertinent standards and codes.Commentary Note:Some piping systems, not defined as corrosion-critical in this standard, must still bebuilt with corrosion-resistant materials as specified in other standards or codes.Examples are sewer lines, wastewater disposal lines, and potable water lines.5.3Normal, Foreseeable and Contingent Conditions5.3.1Select appropriate corrosion control methods and materials (see Section 7)for all of the following conditions. Always take measures, as described inSection 7.2, to prevent sulfide stress cracking (SSC), stress corrosioncracking (SCC) such as caustic cracking, SOHIC, and other rapidenvironmental cracking mechanisms: Maximum normal operating conditions, projected over the design lifeof the system which is specified as a minimum of 20 years,Commentary Note:The design life is specified as a minimum of 20 years. There maywell be circumstances where a longer design life is appropriate, if theequipment is located in a hard-to-repair location. One example is theuse of 50-year sub-sea valves on pipelines because sub-seamaintenance of valves is extremely challenging.Page 10 of 46

Document Responsibility: Materials and Corrosion Control Standards CommitteeSAES-L-133Issue Date: 23 January 2012Corrosion Protection RequirementsNext Planned Update: 18 July 2014for Pipelines, Piping and Process Equipment5.3.2 Process start up, End of run variations and Foreseeable intermittent or occasional operations, such as hydrostatictest, steam cleaning or carryover of contaminants from an upstreamprocess (e.g., caustic from a stripper).Select corrosion control and materials for contingent conditions, such asthose that may be encountered during construction, start-up, shutdown,process upset operations, or the failure of a single component. Alwaystake measures, as described in Section 7.2, to prevent sulfide stresscracking (SSC), stress corrosion cracking (SCC) such as caustic cracking,SOHIC, and other rapid environmental cracking mechanisms.Contingency failure requirements may not require provision for generalcorrosion, localized corrosion, or hydrogen induced cracking, if the timeexposure is very limited. However, additional corrosion control measuresshall be required if the contingent conditions exist for an extended period.Consult the Corrosion Technology Unit, ME&CCD, CSD.Commentary Note:Consideration must be given to potential corrosion of valve trim/seatsduring hydrotest. The type of hydrotest medium must be consideredtogether with likely exposure time and ambient temperature. Companyexperience has shown that certain materials (such as 304 SS) used invalve internals suffer from pitting (and in some cases severe pitting) priorto pipelines entering service. Consequently, consideration of hydrotestmedium, exposure time and temperature may require an upgrade in valvetrim and seat materials. See SAES-A-007 for specific recommendationsfor hydrotest fluids and treatment of hydrotest fluids.5.46For situations not adequately addressed by codes and standards, use theoptimum corrosion and materials engineering practices commonly accepted inthe oil and gas and refining industry, with the concurrence of the Supervisor,Corrosion Technology Unit, CSD/ME&CCD.Determining Corrosive and Crack-Inducing Environments6.1Corrosive EnvironmentsFor design purposes, an environment that meets any one of the conditions listedbelow is corrosive enough to require specific corrosion control measures(see Section 7). A piping system or process equipment predicted to be exposedto such an environment during its design life requires measures to control metalloss corrosion:Page 11 of 46

Document Responsibility: Materials and Corrosion Control Standards CommitteeSAES-L-133Issue Date: 23 January 2012Corrosion Protection RequirementsNext Planned Update: 18 July 2014for Pipelines, Piping and Process Equipment6.1.1Acidic or near neutral pH water phase with an oxygen concentration inexcess of 20 micrograms per liter (20 ppb).Commentary Note:Acidic or near-neutral pH water that has access to atmosphere willcontain up to 8 mg/L dissolved oxygen and is corrosive. Water with a pHof 10 to 12 is considered non-corrosive to steel in many environments.6.1.2A water phase with a pH below 5.5 calculated from available data ormeasured either in situ or at atmospheric pressure immediately after thesample is collected in the field.6.1.3A water-containing multiphase fluid with a carbon dioxide partialpressure 206 kPa (30 psi).Commentary Notes:6.2(1)Systems with CO2 partial pressures between 20.6 kPa to 206 kPa (3 psiand 30 psi) will require corrosion control measures if the expectedcorrosion rate is high (see 6.1.4). Systems with partial pressures below20.6 kPa (3 psi) are usually non-corrosive.(2)Mixed corrosive systems containing both carbon dioxide and hydrogensulfide shall be considered to be dominated by the carbon dioxidecorrosion mechanism when the ratio H2S/ CO2 0.6. Such corrosionsystems are generally called “sweet” when considering general thinning,pitting, and erosion-corrosion. However, note that the systems maycontain sufficient hydrogen sulfide to also meet the requirements of soursystems presented in Paragraphs 6.2.1 and 6.2.2.6.1.4A service condition that would cause a metal penetration rate of76 μm/yr (3.0 mpy) or more. The penetration rate may be from uniformcorrosion, localized corrosion, or pitting. Determine this servicecondition jointly by consulting corrosion engineers from the responsibleoperating organizations and CSD/ME&CCD.6.1.5All soils and waters in which piping systems are buried or immersed.6.1.6A water-containing fluid stream with flowing solids such as scale orsand, which may settle and initiate corrosion damage.6.1.7A water-containing fluid stream carrying bacteria that can cause MIC.6.1.8Insulated and fireproofed systems.Crack-Inducing EnvironmentsThe environments listed below require control measures if the condition isPage 12 of 46

For a detailed explanation of this subject, seeNACE MR0103 paragraph 1.3.5.In the case of uncertainty in requirements between ISO 15156and NACE MR0103, CSD/ME&CCD shall be the final arbiter.6.2.2Piping systems and process equipment exposed to an environment with 50 ppmw total sulfide content in the aqueous phase require the use ofHIC resistant steel that meets 01-SAMSS-035 and 01-SAMSS-043 forpipes and 01-SAMSS-016 for tanks, heat exchangers, and pressurevessels.6.2.2.1Rich diglycolamine (DGA) systems are not required to meetthis requirement. However, the amine stripper, its overhead(exit) gas piping, cooler, and overhead receiver shall befabricated from HIC-resistant materials.6.2.2.2All other rich amine systems shall meet this requirement.Page 13 of 46

Document Responsibility: Materials and Corrosion Control Standards CommitteeSAES-L-133Issue Date: 23 January 2012Corrosion Protection RequirementsNext Planned Update: 18 July 2014for Pipelines, Piping and Process Equipment6.2.2.3Lean amine systems are not required to meet this requirement.Commentary Note:In new plant build the use of HIC resistant material for some ofthe piping and non-HIC resistant material for the remainder willrequire segregation, control, and tracking of the two materialtypes and an effective method to differentiate between the twotypes of material at the construction site. The use of HICresistant pipe throughout a system may reduce costs due tosimplified inventory and tracking.6.2.2.4Caustic systems are not required to meet this requirement.6.2.3Aluminum heat exchangers must not be used in gas stream cryogenicservice where the mercury content is greater than 10 ng/Nm³ (nanogramsper normal cubic meter) in order to avoid liquid Metal Embrittlement(LME). For control measures see Section 7.2.6.6.2.4Environments recognized by other standards or by good engineeringpractice as potential environments for stress corrosion cracking (SCC)require control measures. CSD/ME&CCD shall be the final arbiter inthe resolution of such design questions.Commentary Note:Some SCC environments are listed in SAES-W-010 Paragraph 13.3 andSAES-W-011 Paragraph 13.3. Other amine SCC environments are listedin API RP 945. The conditions cited in the above standards include, butare not limited to, those listed below:1.All caustic soda (NaOH) solutions, including conditions wherecaustic carryover may occur (e.g., downstream of caustic injectionpoints).2.All monoethanolamine (MEA) solutions (all temperatures).3.All diglycol amine (DGA) solutions above 138 C design temperature.4.All rich amino diisopropanol (ADIP) solutions above 90 C designtemperature.5.All lean ADIP solutions above 60 C design temperature.6.Boiler deaerator service (i.e., ambient temperature vacuumdeaerators are exempt).7.Hydrogen service for P-No. 3, 4, and 5A/B/C base materials.8.All diethanolamine (DEA) solutions.9.All MDEA / aMDEA solutions.Page 14 of 46

For carbon steel and alloy steel systems, always use aminimum corrosion allowance of at least 1.6 mm. The standard corrosionallowance is 3.2 mm. If a higher corrosion allowance is required, the partneeds to be highlighted for additional on-stream, inspection coverage.The maximum corrosion allowance is 6.4 mm which may only be appliedwith specific approval of Saudi Aramco. If the calculated requiredcorrosion allowance exceeds 6.4 mm, evaluate alternative measures.Commentary Note:Corrosion allowance will not reduce the corrosion rate of the pipingmaterial. However, the extra wall thickness of the pipe may provide alonger service life if the mode of attack is uniform general corrosion.Corrosion allowances are often not effective against localized corrosion,such as pitting. However, if pitting rates are well defined from historicaldata, adequate corrosion allowance can be viable.7.1.2Acceptable corrosion control measures include, but are not limited to, thefollowing: Corrosion-resistant alloys. Procure austentic and duplex stainlesssteel pipes for on-plot piping in accordance with 01-SAMSS-046.Page 15 of 46
