Pipeline material question
Is there a typical type/grade of steel (more specific than bare steel) that is used in most pipelines?

All the regulations on this can be found in 49 CFR part 195. 49 CFR 195.112 (which describes the requirements for pipeline steel) does not prescribe a specific type of steel and only requires the following:
(a) The pipe must be made of steel of the carbon, low alloy-high strength, or alloy type that is able to withstand the internal pressures and external loads and pressures anticipated for the pipeline system.
(b)The pipe must be made in accordance with a written pipe specification that sets forth the chemical requirements for the pipe steel and mechanical tests for the pipe to provide pipe suitable for the use intended.
49 CFR 195.3 lists standards which have been incorporated into code by reference, and includes many of the most commonly used industry standards for pipe steel and steel for other pipeline components such as fittings and tanks.
