Problems solved by technology

[0004] In view of the above, when targeting large-diameter pipelines, commonly used fluid equipment generally cannot meet the flow requirements of the fluid medium required to complete the purge. In this case, not only the time required for pipeline purge is prolonged, the power consumption of the fluid equipment is large, and There is often the problem of incomplete purging. The present invention provides a method that can reduce the requirements for auxiliary equipment used in pipeline purging

Embodiment 1

[0018] A method that may reduce the requirement for auxiliary equipment for pipe purging includes the following steps performed in sequence:

[0019] 1) Connect the inlet end of the pipeline to be purged with the compressed air source;

[0020] 2) Set a burst disc at the end of the pipeline to be purged to seal the end of the pipeline;

[0021] 3) Put a compressed air source into the pipeline, when the internal pressure in the pipeline reaches or exceeds the bursting pressure of the bursting disc, the bursting disc ruptures, the gas in the pipeline overflows from the end of the pipeline, and the purge of the pipeline to be purged is completed ; and the weakened portion of the above rupture disc is located at the bottom of the sealed end face obtained through it.

[0022] In this embodiment, the set compressed gas source is used to feed compressed gas into the pipeline to be purged, and the set bursting disc is used to seal the end of the pipeline. The internal pressure of th...

Embodiment 2

[0024] This embodiment is further limited on the basis of Embodiment 1. In order to facilitate the purge effect and facilitate the implementation of segmented purge on long-distance pipelines, the compressed air source used in step 1) is mobile air compressor.

[0025] In order to predict the rupture time of the bursting disc and improve the safety of the method, in step 1) or step 2), a process of installing a pressure gauge on the pipeline is also included.

[0026] As a material widely used in mechanical engineering, it can be used as a bursting disc, and at the same time it is convenient for blasting pressure regulation. The bursting disc used in step 2) is single-layer multi-layer bakelite paper or highland barley paper.

Abstract

The invention discloses a method capable of reducing requirements for auxiliary equipment for pipeline purging. The method comprises sequential steps as follows: 1) the inlet end of a to-be-purged pipeline is connected with a compressed gas source; 2) a bursting disk is arranged at the tail end of the to-be-purged pipeline so as to seal the tail end of the pipeline; 3) the compressed gas source is introduced into the pipeline, when the internal pressure inside the pipeline reaches or exceeds the bursting pressure of the bursting disk, the bursting disk bursts, gas inside the pipeline overflows from the tail end of the pipeline, and purging of the to-be-purged pipeline is completed; and the weak part of the bursting disk is located at the bottom of a sealed end surface obtained through the bursting disk. The method is convenient to implement, and meanwhile, the purging effect is good.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering pipeline erection, in particular to a method capable of reducing the requirement for auxiliary equipment used for pipeline purging. Background technique [0002] After the installation of equipment or process pipelines, before leak testing and pressure testing, the pipelines should be purged to remove iron filings, rust, welding slag and other sundries left in the equipment and pipelines, so as to prevent the above sundries from being trapped in the pipeline. During use, the pipeline will be blocked by the fluid, and the valves and instruments will be damaged to ensure the safe operation of special equipment, instruments, regulating valves, pumps, filters and other equipment, and it is also beneficial to the quality of the product. [0003] In the prior art, the means of purging the pipeline are generally water washing, air purging, steam purging and ball cleaning. The above methods...
