Low-pressure pipeline pressurized leakage removing method

Abstract

The invention aims at providing a low-pressure pipeline pressurized leakage removing method. According to the method, pressurized leakage removing can be carried out on a technology pipeline with micro leakage, much inconvenience, caused by water supply and gas supply stop during overhauling, to technology pipeline conveying is avoided, and under most conditions, water supply and gas supply stop for overhauling is not allowed in a pipeline system. By the adoption of the method, the micro leakage appearing in the low-pressure technology pipeline can be subject to pressurized leakage removing under the condition without water supply and gas supply stop; the method is easy and convenient to operate and good in leakage removing effect; according to the method, a quick-setting type leaking stoppage agent is used firstly for leakage stoppage on the leakage position of the low-pressure technology pressurized pipeline, after curing, the pipeline leakage position is subject to leakage stoppage through a winding method, the technology pipeline with the micro leakage can be subject to pressurized leakage removing through the method, and much inconvenience, caused by water supply and gas supply stop during overhauling, to technology pipeline conveying is avoided.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of pressure leakage elimination of general low-pressure process pipelines, in particular to a pressure leakage elimination method of low-pressure pipelines. [0003] 【Background technique】 [0004] In the daily production process of the factory, small leaks often occur in the pressurized pipeline. The general treatment method is to stop the water and gas operation of the faulty pipeline and then carry out maintenance, and repair it by using conventional methods such as electric welding, gas welding, and plastic welding. Welding to eliminate leaks, or adopt conventional leak-elimination methods with pressure to eliminate leaks. Conventional leak-elimination methods under pressure mainly include adjustment leak-elimination method, mechanical plugging method, plug-hole plugging method, sticky plugging method, glue plugging and sealing method Wait. However, the general pressurized leakage elimination method suffe...

Problems solved by technology

[0026] The pipe material is made of various materials such as metal and PVC, and the medium conveyed by the pipe is liquid or gas, such as water, steam, etc. In most cases, the pipe system is not allowed to stop water and gas for maintenance. When there is a small leak in the pressurized pipeline, and at this time the pipeline system is not suitable for maintenance without water or gas, it is also not suitable to use conventional methods such as electric welding, gas welding, plastic welding, etc. to repair and eliminate leaks. The effect of the method is not ideal or the implementation is difficult
