acid corrosion inhibitor. Slows the acid attack on metal.

n: 1. a specific quantity of material that is processed, treated. or used in one operation. 2. in corrosion control, a quantity of chemical corrosion inhibitors injected into the lines of a production system. 3. in oilwell cementing, a part of the total quantity of cement to be used in a well. 4. in pipelining, a quantity of one weight or type of crude or liquid product pumped next to one of different weight or type.

slugging a chemical such as a biocide or a corrosion inhibitor in high concentration to accomplish either placement or super concentrated treating.

n: in corrosion control, the injection of a quantity of chemical corrosion inhibitors into the lines of a production

n: a compound in which chromium has a valence of 6, e.g., sodium bichromate. Chromate may be added to drilling fluids eimer directly or as a constituent of chrome lignites or chrome lignosulfonates. In certain areas, chromate is widely used as a corrosion inhibitor, often in conjunction with lime.

corrosion inhibitor treatment.

n: in corrosion control, the constant injection of small quantities of chemical corrosion inhibitors into the lines of a production system.

n: a metal strip inserted into a system to monitor corrosion rate and to indicate corrosion inhibitor effectiveness. corrosion fatigue n: metal fatigue concentrated in corrosion pits. See fatigue.

a representative piece of metal cut to a specific size and shape that is immersed in a test bath of placed in the flow stream to enable an estimation of the active corrosion occurring in a given set of conditions.

n: a chemical substance that minimises or prevents corrosion in metal equipment.

a chemical substance or combination of substances that, when present in the environment, prevents or reduces corrosion (NACE).

n: The material that can repress or stop corrosive media eroding the metal.
