Causes of water leakage for seamless steel pipe and its repair methods

Causes of water leakage of seamless steel pipe


1. Pipeline aging: When the seamless steel pipe is used for a long time, the pipeline will naturally age, which will lead to pipeline corrosion, deformation and wear, and eventually lead to water leakage.


2. External force damage: During installation of seamless steel pipe, improper operation may damage the pipe, resulting in pipe rupture, deformation and even water leakage.


3. Pipeline corrosion: Due to the chemical composition and movement state of water, long-term use will lead to pipeline rust and corrosion, which will lead to water leakage of seamless steel pipes.


According to the factors can be divided into


1 raw material factors: poor quality tube blank will appear internal and external warping, scarring, cracks and so on.


2. Temperature factor: The first important process of seamless steel pipe production is heating, and poor heating (uneven, insufficient temperature, etc.) will cause internal warping.


3. Equipment factor: Every equipment component will affect the quality of the pipe from the time it comes out of the furnace. For example, the collision and scraping of equipment parts will cause outward warping and pits; If the piercing machine is not smooth, it will cause the head of the tube blank to be caught in the water, or the head will become warped and the inner layer will break.


4. Technological factors: The technological problems are also quite complicated, including equipment adjustment, equipment failure, and internal cracks and scars of seamless steel pipes caused by the wear of technological components (plugs, guide plates, rollers, etc.).


Leakage repair method of seamless steel pipe leakage


1. Water stop: Water stop is a commonly used emergency treatment method for water leakage of seamless steel pipes, which is suitable for small and medium-sized water leakage. Before use, it is necessary to deal with the leakage point first, and then roll the water stop into a strip with a certain length, wrap it around the leakage point, and wrap the water stop once to make it tightly sealed.


2. Leak-trapping glue: Leak-trapping glue is a commonly used material for repairing water leakage of seamless steel pipes, and its use method is relatively simple and convenient. Before use, it is necessary to clean the surface of the leakage point, keep it dry and clean, and then apply the leakage-repairing glue to the leakage point and wait for it to dry.


3. Replace the pipeline: If the pipeline is seriously aged or leaks too much and needs a more thorough repair method, it is necessary to replace the seamless steel pipe at the leaking point. It is necessary to remove the original pipeline first, and then replace it with a new pipeline to ensure that the diameter and installation method of the new pipeline are the same as the original pipeline.


In a word, there are many reasons for the water leakage of seamless steel pipes, and the treatment methods need to be selected according to the specific situation. To ensure the safety and quality, it is suggested that care should be taken when repairing the leakage of seamless steel pipes.
