SUBSTANCE: invention relates to oil and gas industry, specifically to devices for sampling well products from pipelines. Disclosed is a sampler, comprising a housing connected to a pipeline, with a gland and a gland cover, sampling valve and a tube tightly inserted into the housing due to the gland and interconnected with a branch connected to the sampling vessel. Housing is installed horizontally and connected to pipeline through sampling valve. Housing is equipped with a hole from below and a protrusion on the inner wall. Tube is made with outer diameter, providing sliding fit inside housing to prevent ingress of sediment between them, and is equipped with a longitudinal groove for a projection of the housing to prevent rotation and a lower channel communicated with the opening of the housing. Tube is inserted into the housing with the possibility of tight interaction with the inner end face with the gland of the housing, and with the outer end face – with the gland cover; at that, the branch is rigidly connected to the housing and interconnected with the hole of the housing.

EFFECT: possibility to clean the housing from deposits without complete disconnection of the sampler from the pipeline or the well due to the quick-change internal tube.
