Mitigating corrosion and surface scale formation in a sour gas well includes providing an oil-based liquid to a sour gas well having carbon steel tubing with iron sulfide on a surface of the carbon steel tubing, contacting the carbon steel tubing with the oil-based liquid, and adsorbing a first portion of the oil-based liquid onto the iron sulfide, thereby yielding a hydrophobic coating on the carbon steel tubing.

Processes and systems for preparing sections of pipeline pipe for machine processing to form pin and box ends for assembly into pipelines using mechanical press-fit pipe joints. The prepared pipe sections are prepared to be fully measured and documented during both manufacturing and assembly. Installed pipelines include pipeline data monitoring systems coupled to a pipeline data management center for receiving, archiving, and analysis of the data records to aid in administration, operation and management, and troubleshooting of pipelines.

Anti-corrosion nanoparticle compositions include a carrier and a plurality of nonionic metal nanoparticles. The metal nanoparticles can be spherical-shaped and/or coral-shaped metal nanoparticles. The nanoparticles are selected so as to locate at the grain boundaries of a metal or metal alloy when the anti-corrosion composition is applied to the metal or alloy, thereby reducing or preventing intergranular corrosion of the metal or alloy.

A tube fitting is provided with a resin coating layer over a coated region surfaces of a threaded portion and a contact portion. The resin coating layer includes a polyethylene based substance, a lubricant, and solid particles. When mass per unit area w (g/m.sup.2) is defined as a value obtained by dividing the mass difference between a state with the resin coating layer and a state without the resin coating layer by the surface area of the coated region, the mass per unit area w satisfies a relation 0.79<w<10.07.
