MOBILE CHAMBER FOR LAUNCHING AND RECEIVING IN-PIPE DEVICES AND CLEANING AND DIAGNOSTICS TOOLS Russian patent published in 2023 - IPC B08B9/04 

FIELD: oil and gas industry.

SUBSTANCE: mobile chamber for launching and receiving in-line devices and cleaning and diagnostic tools, containing a housing, one end of which is made in the form of an end valve, and the other end is made in the form of an eccentric transition, to which one end of the line pipe is connected. In this case, the lower part of the housing is located on the same level as the lower part of the line pipe. Piping, made in the form of a bypass line, which is connected to the main outlet pipe, which connects the bypass line to the body and which is connected to the body closer to the eccentric transition. An additional outlet pipe that connects the bypass line and the camera body. One end of the bypass line is configured to connect, at the installation site of the mobile chamber, with a gas sampling pipe located opposite the end valve and connected to the main pipeline, and the second end of the bypass line is configured to connect, at the installation site of the mobile chamber, with the outlet pipe gas connected to the main pipeline. The first pressure relief unit, which is located on the body, the second pressure relief unit, which is located on the line pipe. A pressure equalization line, the ends of which are connected to the bypass line and to the housing. The line pipe in the upper part is equipped with an indicator for passage of a slug. A winch for the cable, which is installed on the body and a pipe for entering the cable, which is connected to the body. Adjustable single-column supports, which are connected to the frame at one end and to the bypass line at the other end and are made with the ability to adjust the location of the bypass line in height relative to the body, line pipe, gas sampling pipe, and gas outlet pipe. Two-column supports, which are connected to the frame at one end and to the housing at the other end, line pipe, gas sampling pipe, and gas outlet pipe and are made with the ability to adjust their height position relative to the main pipeline.

EFFECT: simplified on-site installation of a mobile chamber for launching and receiving in-line devices and cleaning and diagnostic tools.
