An object of the present invention is to achieve long-term anticorrosive effect for a wide range of articles such as iron castings, steel sheets, and galvanized steel sheets. As a means for achieving the object, the present invention provides a resin molded product structured in such a way that polyolefin resin layer 1 containing an ammonium salt of carboxylic acid, and polyolefin resin layer 2 containing a metal salt of aliphatic carboxylic acid, are stacked.

The invention relates to a composition for inhibiting corrosion of the upper part (or roof) of a pipeline for conveying wet hydrocarbons, i.e. hydrocarbons comprising a variable amount of water, said composition comprising at least one Amine 1 with vapor pressure greater than or equal to 10 mmHg, and at least one. Amine 2 with vapor pressure greater than or equal to 0.1 mmHg and strictly less than 10 mmHg. The invention also relates to the use of such a composition, and also to the method of inhibiting top-of-line corrosion employing said inhibitor composition.

A nuclear reactor plant including a reactor; a coolant in the reactor; a gas system connected to the reactor and adapted to provide a gas supply to and gas removal from a space above the coolant; and a device for injection of gas into the coolant. The device is installed partially in the coolant and partially in the space above the coolant, and is adapted to supply gas from the space above the coolant to the coolant. The gas system and device are configured to carry out steps including: supplying gas to be injected into the coolant from the gas system to the space above the coolant space; injecting gas into the coolant by maintaining the gas pressure higher than coolant pressure in the device; and injecting gas into the gas system from the space above the coolant.
