I.Pambuka

Corrosion coupons are vital instruments employed to identify and evaluate the extent of corrosion within pipeline systems. They provide an accurate assessment of the internal corrosion status, which is crucial for the pipeline’s maintenance and preservation. Currently, the corrosion coupons in use both domestically and internationally are generally successful in detecting pipeline corrosion. However, the majority of these devices necessitate pipeline depressurization and cessation of operations, which can lead to substantial economic losses. In response to this challenge, our company has developed a specialized tool that allows for the extraction of the corrosion coupon even while the pipeline is under pressure. This removes the need for pipeline depressurization and shutdown. The primary components of this tool are fabricated from stainless steel, conferring resistance to both acidic and alkaline conditions, as well as superior corrosion resistance. The retrieval tool operates through a mechanical contact mechanism, ensuring both sensitivity and reliability.

VI. Maintenance

The maintenance of the pressure retrieval tool, crucial for its longevity and functionality, involves several key steps to be undertaken after each use. Firstly, it is critical to ensure that the tool and each of its components are meticulously cleaned. This step involves wiping off any residual material or debris that may have accumulated during use.

The next step in the maintenance process is to thoroughly dry the tool. It’s important to prevent any moisture from remaining on the retrieval tool as this could potentially lead to rust or other forms of corrosion over time, especially if the tool is stored in a humid environment.

Finally, attention must be paid to all areas of the tool that house O-rings. These areas should be adequately greased after every use. The application of grease is a preventative measure that helps to ward off corrosion damage over time. It also maintains the flexibility and sealing ability of the O-rings, ensuring they perform effectively during each use.

In summary, regular and meticulous cleaning, drying, and greasing of the pressure removal tool and its components are vital steps in preserving its functionality and extending its lifespan.
