AI Technical Summary

Technical Problem

In the existing technology, there is a lack of specific experimental research and evaluation methods for the corrosion behavior of bent pipes in indirect cooling systems. Traditional corrosion control methods are difficult to adapt to dynamic water quality changes, and existing monitoring methods are difficult to capture the dynamic response relationship between instantaneous changes in water quality parameters and corrosion processes. As a result, bends become high-risk areas for corrosion and leakage, affecting the safe and stable operation of the system.

Method used

A corrosion-resistant material testing device for SCAL type intercooling systems was designed, comprising a water tank, a corrosion water sample preparation unit, an online sampling unit, and a water purification unit. By simulating the corrosion conditions of bent pipe fittings, the device monitors water quality changes in real time, realizes water sample recycling, and provides a test platform that comprehensively simulates actual operating conditions.

Benefits of technology

This device can accurately assess the corrosion resistance of pipes, reduce testing costs, improve testing efficiency and accuracy, provide more accurate corrosion warnings and protection solutions, and ensure the safe and stable operation of the system.
