The sour service definitions proposed by EFC document 16 were developed for oil country tubular goods, and are strictly only applicable to such materials, as indeed stated in Section 7.2.1 of that document. Nevertheless, it is also applied to welded steels in Table 8.1.
A515GR.70 HIC Steel Working conditions where wet H2S prevails are often described as sour service conditions and the term sour gas can be also be used in this context. As more fields rich in H2S are exploited, and this is increasingly the case, the problem is increasingly significant for equipment fabricated in potentially sensitive carbon-manganese (C-Mn) steels.
Sour Service Steel Grades offered by U. S. Steel Tubular Products:API L80 is manufactured to API specification 5CT. This is a controlled yield strength material with a hardness testing requirement. L80 is often used in wells with sour (H2S) environments. API C90 is an API controlled yield strength grade generally for use in sour condensate wells. Extensive hardness testing is required along with Sulfide
Definition of Sour Service - EngStackSour service can be described as follows:Gas phase where the H2S partial pressure exceeds 0.05 psia (0.34 kPa). Single phase liquids that are in equilibrium with a gas phase, where the gas phase H2S partial pressure exceeds 0.05 psia (0.34 kPa).
Requirements for steel plates in sour serviceApr 30, 2016 · 6Requirements for steel plates in sour service Verfasser/Dokument 6 The view of the steel plate manufacturer Steel plate requisitions reflect an increasing demand for plates with improved properties for sour service Large variety of customer requests:- many specifications based on published recommendations or test methods (e.g. NACE MR 0175
Feb 18, 2004 · Sour service refers specifically to the effects of H2S - if you do not have any, then sour service is not an issue. CO2 corrosion is a different issue and many companies, like Shell for example, have developed assessment procedures for CO2 service. odle1128 (Mining) 29 Dec 03 14:32
Sour Service - VallourecSour Service materials are carbon low alloyed steels with microstructure developed to resist hydrogen embrittlement caused by H2S which is commonly present in oil and gas wells.
Sour Service Steel U.S. Steel Tubular ProductsU. S. Steel Tubular Products produces a wide offering of proprietary steel grades ideal for sour service environments. U.S. Steel Tubular Products Proprietary Sour Service Steel Grades:USS GT80S is a proprietary controlled yield strength U. S. Steel grade generally for use in severe sour service wells. Inspection, testing and dimensions are in accordance with API L80.
A proprietary product developed for sour service applications that has a NACE tested tube and a reduced yield strength tool joint. The drill pipe body is produced from a proprietary grade material and each heat of material is SSC tested to 70% SMYS in accord with NACE TM-01-77, Method A, Test Solution A.
Vallourec:Deep expertise in sour serviceSour service is one of the toughest challenges in hydrocarbon production, and due to a recent dip in oil prices, well operators are now looking for even more cost-effective solutions that combine high-strength steels and resistance to sulfide stress cracking.
Valves and Instrumentation in sour service? - EngStackValve parts that are not subject to sour service dont need to comply. Valve springs should be made of material resistant to corrosion cracking in the presence of H 2 S. Inconel 718, Alloy 925, or MP35N materials should be used for springs in moderate and severe sour service. Inconel X 750 is acceptable in mild sour services. Valve Packing:
Oct 24, 2020 · Sour service is referred to exploration and production environments in oil and gas that have enough H2S that could cause CRACKING of metallic materials. The oil and gas industry recognize sour service as one of the toughest challenges in hydrocarbon production. H 2 S cracking is a risk to the integrity of assets and operations.
sour service - Traduzione in italiano Dizionario LingueeListed in NACE MR 01 75 for sour service and having gained ASME Approval for Pressure Vessel applications, Ferralium  255-SD50 is tested to the highest degree using tests designed to guarantee that the trade-marked product possesses high integrity, a correct phase balance and the absence of sigma and other deleterious phases.What is a Sour Service? - Definition from CorrosionpediaJul 23, 2018 · Sour service describes a type of pipeline or storage vessel that is filled with substances that contain hydrogen sulfide (H 2 S) or sulfuric acid (H 2 SO 4). In order for the service to be considered a sour service, the hydrogen sulfide levels must be above a certain threshold. Sour service can subject the vessel material to corrosion.
