Problems solved by technology

In the preparation and installation process of the instrument pressure guiding pipe, the elevation and direction of the pressure guiding pipe must be determined according to the instrument piping installation diagram and the instrument layout plan. However, due to the complex environment of some process pipelines and control points on the equipment , construction collisions with other professions are often unavoidable, and the pressure guiding pipe may make way for process pipes and electrical piping and may change the elevation and direction, so it is unrealistic to prepare the instrument pressure

Abstract

The invention relates to a preparation method of an instrument pressure guide pipe, which belongs to the technical field of instrument pressure guide pipes and comprises the following steps of: 1, determining the elevation and the trend of the instrument pressure guide pipe according to the actual condition of an on-site process pipeline when the on-site instrument pressure guide pipe is prepared; step 2, using a preparation tool to simulate the length and the direction of the process pipeline along the trend of the process pipeline, so that the preparation tool forms a pipeline model; and step 3, performing bending one-time forming on the pressure guide pipe according to the size and shape of a pipeline model formed by the preparation tool, and completing preparation and installation of the instrument pressure guide pipe after forming. When the instrument pressure guide pipe is prepared and installed, the preparation tool is adopted to simulate the process pipeline to prepare the model, then the pressure guide pipe is bent according to the simulated and prepared model, the method is low in cost, the size of the instrument pressure guide pipe is convenient to measure, the pipe distribution direction is easy to determine, the instrument pressure guide pipe is rapidly prepared, and the instrument pressure guide pipe can be formed at a time in the bending process.

Description

technical field [0001] The invention belongs to the technical field of instrument pressure guide tubes, and in particular relates to a preparation method of instrument pressure guide tubes. Background technique [0002] The instrument pressure guiding pipe is inseparable from the process pipeline and equipment. The pressure guiding pipe is a kind of pipeline that is directly in contact with the process medium and has material inflow. It is the most used, most demanding and most complicated pipeline for instrument installation. . Since the pressure guiding tube is in direct contact with the process medium, the selection of the tube is related to the physical properties, chemical properties and operating conditions of the measured medium. The general requirement is that the pressure guiding tube must have a certain strength when working under pressure or normal pressure. And tightness, so this kind of pipeline should choose seamless steel pipe. In the preparation and install...
