Piston sampler procedure

WebbAlternatively, sampling can be performed by using of floating piston cylinder: A hydrocarbon fluid sample is transferred under pressure from a source to a moving piston cylinder. The piston-type cylinder is designed to collect fluid samples by displacing a pressurizing fluid (usually an inert gas) at sampling pressure. WebbThe sampling quantity is between 0.5 and 3 ml each piston stroke. The sampler type KS-P™ is a cost-effective solution to take constant samples from a production process. A …

The cylinder is first evacuated and filled with a pressurizing fluid (for example, glycol or a synthetic oil) on one side of the floating piston. The top of the cylinder (evacuated side) is then connected to the sampling location from which the sample is to be taken.

WebbAn outer circle, 5 mm in diameter, surrounding the 3 -mm circle, means that sampling has been carried out. In -filling of the upper or the lower half of the circle indicates that samples can be considered as disturbed respectively undisturbed, e.g. taken by means of an earth auger or a piston sampler. The 3-mm circle refers to soil investigation. Webb1 jan. 2016 · The piston sampler (Practice D6519) uses a thin-walled tube. However, the piston samplers are designed to recover soft soils and low-plasticity soils and the thin-walled tubes used must be of lower C r of 0.0 to 0.5 %. Other piston samplers, such as the Japanese and Norwegian samplers, use thin-walled tubes with 0 % C r (see Appendix X1 ).
