Does pressure sealant for pipeline leaks cause corrosion?

The pressure sealant itself does not cause corrosion to pipelines. Pressure sealant is a high polymer material, primarily composed of synthetic rubber and fillers, which include curing agents, accelerators, toughening agents, and more. Under normal usage conditions, pressure sealant does not react chemically with pipeline materials and does not cause corrosion. However, if the pipeline already has corrosion or damage, using pressure sealant may affect the pipeline's lifespan. This is because cleaning the pipeline surface of rust and dirt during application can accelerate the corrosion process. Additionally, improper use of pressure sealant can also impact the pipeline's lifespan. Therefore, when using pressure sealant, attention should be given to the following points: first, ensure the pipeline surface is clean and dry to avoid contact with impurities on the surface; second, during the operation, try to avoid damaging the pipeline surface; lastly, use the pressure sealant according to the product manual's instructions, avoiding over-heating, over-curing, and excessive exposure to air. If issues arise during use, it is recommended to contact professionals for maintenance and replacement.
