FIELD: pipeline engineering.
SUBSTANCE: sampling device comprises housing with sealing gland, sampling tube, and stop vale arranged at the end of the sampling tube. The sampling tube is connected with the housing by means of a threaded pair interposed between the pipeline and gasket unit. The length of the thread on the sampling tube exceeds that on the housing by the value of inner diameter of the pipeline.
EFFECT: enhanced pressure tightness and prolonged service life.
