Sour service pipelines, which transport fluids containing hydrogen sulfide (H₂S), typically use materials that are resistant to corrosion and stress corrosion cracking. Common materials include carbon steel with specific corrosion-resistant alloys, such as those containing nickel or chromium, as well as stainless steel grades like 316 or 904L. In some cases, alloyed materials like duplex stainless steel or special coatings are employed to enhance durability and safety in corrosive environments. Proper material selection is crucial to ensure the integrity and longevity of the pipeline system in sour service conditions.

What is difference between non sour service sour servce pipeline?
Type your answer here... H2S content. Sour service environments are defined by NACE International specification MR0175 as "fluids containing water and hydrogen sulphide (H2S) that is at a total pressure of 0.4MPa (65psia) or greater, and if the partial pressure of hydrogen sulphide in the gas is greater than 0.0003MPa (0.05psia)".
What is sweet service in pipeline engineering?
Sweet service in pipeline engineering refers to the transportation of hydrocarbons, particularly natural gas and crude oil, that contains little to no hydrogen sulfide (H2S) or other corrosive compounds. This type of service is generally less corrosive and requires less stringent materials and maintenance standards compared to "sour service," which involves fluids that contain significant levels of hydrogen sulfide. Consequently, sweet service pipelines can often be constructed using standard carbon steel materials, making them more cost-effective and easier to manage. Proper classification between sweet and sour service is crucial for ensuring the safety and longevity of pipeline systems.
When was Alyeska Pipeline Service Company created?
Alyeska Pipeline Service Company was created in 1970.
What is sour service?
Sour service will contain higher H2S content (more hydrogen sulfide).
Pipe material used in construction of cross country pipeline?
concrete
Who is the food service on Alaska pipeline?
NMS Food Services is one the major food suppliers on the Trans Alaska Pipeline. They have been in that position since about 1971.
What is the alskan pipeline and where does it begin and where does it end?
The Trans-Alaska Oil Pipeline, which is owned by the Alyeska Pipeline Service Company, was built to bring crude oil from the North Slope at Prudhoe Bay to Valdez, the most ice-free port in Alaska.
Can aluminum be used in sour gas service?
No, aluminum is not recommended for use in sour gas service due to its susceptibility to corrosion by hydrogen sulfide (H2S) present in sour gas environments. Materials with higher corrosion resistance, such as stainless steel or nickel-based alloys, are preferred for sour gas applications.
Identify three pieces of information that should always be printed on a pipeline warning?
A pipeline warning should always include the type of hazardous material being transported, clear instructions for emergency response, and contact information for the pipeline operator or relevant authorities. Additionally, it should indicate the potential dangers associated with the material and any necessary safety precautions for nearby individuals.
What is fullform of TLP in pipeline material?
The only reference to pipes found is Tight In Pipe as a pipe reinforcement technique.
Is the crude sour or wet service?
Crude oil can be classified as sour or sweet based on its sulfur content; sour crude contains higher levels of sulfur, while sweet crude has less. Wet service typically refers to environments where water is present, which can occur with both types of crude, especially during extraction and transportation. Therefore, crude oil can be either sour or sweet, and it can be involved in wet service conditions depending on the specifics of the operation.
