Abstract

The invention relates to the technical field of a production stoppage-free temperature measuring method for an oil pipeline, in particular to a pressed punching production stoppage-free temperature measuring method for a pipeline, comprising the following steps of: welding a sleeve installation seat on the pipeline and installing a valve at the upper part of the sleeve installation seat; then installing a puncher connecting shell on the valve, opening a valve and punching a temperature measuring hole on the pipeline by using a punching cutter; closing the valve, dismounting the puncher connecting shell, taking the punching cutter down and installing a thermometer sleeve on a punching shaft; then installing the puncher connecting shell on the valve, opening the valve to install the thermometer sleeve on the sleeve installation seat; and finally taking off the valve and the puncher connecting shell and installing a thermometer or a thermocouple in the thermometer sleeve to measure temperature. The invention has convenient use; by using the method, the temperature measuring hole can be punched on the pipeline under the condition of no production stoppage so that the purpose of rapidly, safely and reliably installing the thermometer sleeve without stopping production is achieved, and therefore, the invention greatly lowers production cost and simultaneously reduces the installation difficulty of a temperature measuring device.

Description

1. Technical field [0001] The invention relates to the technical field of a method for measuring temperature without stopping production of an oil pipeline, and relates to a method for measuring temperature without stopping production by punching holes under pressure in a pipeline. 2. Background technology [0002] At present, for the temperature measurement of the liquid in the oil pipeline in use, it is usually to shut down the pipeline first, empty the liquid in the pipeline, then punch holes or openings in the pipeline, and finally block the welding sleeve, and install a thermoelectric generator in the sleeve. Measure the temperature with a coupler or a thermometer. Therefore, the existing method for measuring the temperature of the liquid in the oil pipeline has the following disadvantages in actual use: not only does it cause interruption of transportation and production, but also the installation steps are cumbersome, the construction efficiency is low, and there are ...
