Pipe Wall Thickness Monitoring for Early Corrosion Breach Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fire sprinkler systems, especially wet pipe systems, are prone to damage from freezing temperatures and accidental water discharge, and existing monitoring methods fail to effectively detect corrosion before it leads to system breaches and costly damage.
Innovation Solution
A corrosion monitoring system is implemented in fire sprinkler systems, featuring a pipe with varying wall thicknesses and a sealed chamber with sensors to detect pressure changes, allowing for early detection of breaches and preventive action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a wet pipe sprinkler system is used, then fire protection effectiveness is improved, but the system becomes vulnerable to freezing damage
Solution Approach 1:
The patent introduces a corrosion monitoring device as an intermediary component between the water supply and the sprinkler system. This device includes a sensor that detects corrosion products in the water, providing early warning before corrosion can compromise the system's integrity or create blockages that would interfere with fire suppression effectiveness.
2Device complexity
If corrosion monitoring is not implemented, then system simplicity is maintained, but early detection of corrosion breaches is lost
Solution Approach 1:
The corrosion monitoring device performs preliminary detection of corrosion products in the water supply before they can cause significant damage to the sprinkler system. By detecting corrosion early through sensor analysis of water samples, the system enables preventive maintenance actions before corrosion breaches occur, thereby maintaining system reliability without requiring complex real-time monitoring of the entire piping network.
