    FAQ

    description2

    • Q: Can APP plugging rods be used for high-temperature steam pipelines?

      A: Yes! The high-temperature version uses Inconel 625 alloy + flexible graphite seal, with a temperature resistance of 550°C. It has been successfully used for temporary plugging of steam main pipelines in thermal power plants, and the sealing stability has passed the ASME B31.1 test.
    • Q: Will the sealing performance of the plugging rod decrease after repeated use?

      A: The sealing unit adopts a quick-change design, and a single replacement takes only 2 minutes, reducing the spare parts cost by 80%; the main structure has passed 500,000 fatigue tests, and the performance always meets API standards.
