Solder joints on boiler pipes leak during initial heat-up due to thermal expansion, requiring rework.

Pressure testing with nitrogen works for brazed joints but not for low-temperature solder joints; instructor says leaks are expected, implying no reliable way to prevent them.

accepts leaks as normal during heat-up

Implied Software Gaps

Predictive joint integrity testing software that simulates thermal expansion before system is live

App Concept

PipeJoint Pro

PipeJoint Pro is a training and diagnostic tool that simulates thermal expansion stresses on solder joints before installation. It uses controlled heating to identify weak joints, reducing rework and leaks. Trainees can practice and get real-time feedback on joint quality.

Key Features

Simulated thermal expansion stress testing
Real-time joint temperature monitoring
Pass/fail grading with leak detection
Practice mode for trainees

Target Users: Plumbing apprentices and trade school instructors in the plumbing industry

Revenue Model: $199 one-time purchase per unit, with $49 annual software subscription for updates and analytics
