The problem of running, emitting, dripping and leaking is a headache in today's safety production environment. The equipment operates continuously for a long time, and the sealing elements of the pipeline are prone to failure and leakage due to vibration, pressure, stress, temperature difference, aging and other factors.

The continuous evolution of control technology for leakage

In the past, the repair method was to remove the parts and replace the sealing components with new ones. In this way, it is time-consuming and laborious. Improper assembly may lead to poor sealing or damage to other components, resulting in secondary damage, affecting the use effect and increasing maintenance costs.

At present, FusiBlue can be used ® Polymer composite material plugging technology solves this problem. This technology does not need hot work and avoids potential safety hazards in the repair process. After strengthening the protection of the leakage part, it is equivalent to thickening the thickness of the leakage part, which can prevent the leakage part from secondary leakage for a long time.

Field Case of Leakage Treatment with Polymer Materials

In 2022, a power plant has been cooperating well with our company (Fushilan Company) in leakage control for many years. During this maintenance, we were contacted to deal with several perennial oil leakage problems. This time, the main treatment part is the leakage of many hydraulic pipe fittings of the air preheater and the slag dryer. Polymer composite materials are used to treat the leakage on the site. After the repair of the equipment, the operation effect is very good, meeting the established requirements of the enterprise. The specific repair steps are as follows:

1. The leakage surface of the hydraulic pipeline shall be polished to ensure that the surface is rough;

2. Wipe the polished parts with anhydrous ethanol to ensure that the repaired parts are clean and dry;

3. Mix the Fushilan 2296 material in proportion and apply it to the repair site;

4. After the 2296 material is cured, apply Fushilan 3223 rubber material.
