The topic is in reference to any pipelines regulated under 49 CFR part 195, the full scope of this part can be seen here: (https://www.ecfr.gov/current/title-49/subtitle-B/chapter-I/subchapter-D/part-195/subpart-A/section-195.1).
In more layman's terms these pipelines transport hazardous liquids (most commonly oil or petroleum products) large distances. In practice these can range from hundreds of feet to thousands of miles with a wide variety of diameters. The most common diameters would be in the 4-12 inch range.

Good Morning,
Any process that can mitigate corrosion is acceptable including repair processes.
Processes may work with the pipeline full or drained.

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.

Good morning,
1. Pipelines may have internal coatings, but this is uncommon. Most internal pipe surfaces are bare steel.
2. Technologies may be targeted towards either new or existing pipelines.
Thanks!

Good Morning,
Yes, ideas only dealing with detection will be considered! Ideas may do any of prevention, detection, or mitigation, or any combination of the three.
1) Primarily yes. The topic refers to 49 CFR part 195 the full scope of which can be seen here (https://www.ecfr.gov/current/title-49/subtitle-B/chapter-I/subchapter-D/part-195/subpart-A/section-195.1). In practice hydrocarbons are by far the most common substances transported.
2) A variety of products are transported via these pipelines including crude products, so solutions for any environments will be accepted. In practice, pipelines transporting unrefined, more corrosive fluids experience more internal corrosion issues. However, other pipelines are not immune to internal corrosion so solutions for those services will be considered.
3) This is difficult to answer without knowing the exact nature of the proposal. Generally the Phase I project should act as a proof of concept for the technology at more than a theoretical level. If modeling/machine learning will be part of the final technology, then it would be a good inclusion in the phase I proposal.
4) Design requirements for pipelines can be found here (https://www.ecfr.gov/current/title-49/subtitle-B/chapter-I/subchapter-D/part-195/subpart-C). As long as the pipeline meets these minimum requirements it's allowable. The cost/benefit analysis of higher quality steel is up to the pipeline operator and may differ between operators.
