n: 1. a vessel or tank that receives and temporarily stores a liquid used in a continuous process in a gas plant. See drip accumulator. 2. on a drilling rig, the storage device for nitrogen-pressurised hydraulic fluid, which is used in operating the blow out preventers. See blowout preventer control unit.

n: Used to store nitrogen that provide the hydraulic oil energy for BOP operation.

n: one of usually two, three, or more mud tanks that holds drilling mud that is being circulated into a borehole during drilling. They are called active tanks because they hold mud that is currently being circulated.

n: (RSPA) a DOT agency that oversees the Office of Pipeline Safety, intermodal containers, highway portable tanks, railroad cars, and anything used in interstate or international commerce not regulated by the coast guard. Under OPA, RSPA has authority over onshore oil and hazardous materials pipelines that are used in interstate commerce. Address: 400 7th Street SW;Washington, DC 20590;(202) 366-4433.

n: The gas-holder tank connected with discharge line of reciprocal pump. It is a air cushion aerated by compressive air, used to absorb or decrease fluctuation of pressure and delivery capacity disproportion when reciprocal pump works.

n: in tank sampling, a sample that is obtained by submerging a stoppered beaker or bottle to a poinias near as possible to the draw-off level, then opening the sampler and raising it at a rate that makes it about three-quarters full (maxi- mum 85%) as it emerges from the liquid.

n: a weight installed in a tank to which the guide wires or cables for an automatic tank gauge float are attached to hold them taut and plumb.

n: a type of thermometer used on oil tanks. The graduated part of the thermometer is angled at least 90ﾰ from the temperature-sensitive portion. The angle conforms to the shell of the tank and permits easy reading of the instrument.

n: a measuring device installed on the outside of a tank to permit observation of the depth of the liquid inside.

n: the flexible measuring or connecting element that is used to measure the liquid level in tanks by the automatic gauge method.
