The solenoid valve may include a coil, a stem core tube, and a core. The coil may include one or more electrical leads configured to provide the coil with an electric current. The coil may be configured to convert the electric current to a magnetic field. At least a portion of the stem core tube may be insertable within a coil channel. At least a portion of the core may be insertable within an end of the stem core tube and may be moveable within the stem core tube via the magnetic field. At least one of the stem core tube or the core may be fabricated from 434 stainless steel and treated with one or more corrosion prevention processes. The solenoid valve may be couplable to one or more components of the brewing apparatus. The brewing apparatus may be dimensioned to fit within a compartment of the aircraft galley.

A hydrocarbon tank system environment corrosion inhibitor includes use of inert gas, preferably Nitrogen, to blanket ullage and interstice through the tank system. Blanket gas is provided via controller into coupling to access ullage. Blanket gas is provided upon fueling events to stabilize the pressure in the system and prevent entry of atmospheric air and water (vapor). Blanket gas may be continuously run into the ullage and/or other spaces in tank system. A controlled system allows for monitoring of pressures in the tank, and thereby identifies pressure events and even leaks in system due to unusual events, or general loss of pressure.

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.

Provided is a pressure-sensitive adhesive (PSA) sheet including a PSA layer formed from a PSA composition including a base polymer, crosslinking agents of two or more species having mutually different types of crosslinkable functional groups, and an azole-based rust inhibitor. Here, one of the crosslinking agents of two or more species is an isocyanate-based crosslinking agent. Monomeric components constituting the base polymer include a carboxy group-containing monomer. The amount of the azole-based rust inhibitor in the PSA layer is less than 8 parts by weight with respect to 100 parts by weight of the base polymer.

A conformal coating composition for protecting a metal surface from sulfur related corrosion includes a polymer and metal nanoparticles blended with the polymer. In accordance with some embodiments of the present invention, an apparatus includes an electronic component mounted on a substrate, metal conductors electronically connecting the electronic component, and a polymer conformal coating containing metal nanoparticles overlying the metal conductors. Accordingly, the metal nanoparticle-containing conformal coating is able to protect the metal conductors from corrosion caused by sulfur components (e.g., elemental sulfur, hydrogen sulfide, and/or sulfur oxides) in the air. That is, the metal nanoparticles in the conformal coating react with any corrosion inducing sulfur component in the air and prevent the sulfur component from reacting with the underlying metal conductors.
