technological breakthrough！Hunan Tianzhuo Pipe Industry's patent solves the problem of leak monitoring，Implementation of coated plastic pipes “active warning”
2025 year 1 moon，Developed by Hunan Tianzhuo Pipe Industry Co., Ltd “A corrosion-resistant coated spiral steel pipe structure” Formally obtained national patent authorization（Announcement No. CN 222229737 U），This technology has innovatively solved the industry pain point of small leaks that are difficult to detect at the connection parts of plastic coated pipes，To provide water supply、The safe operation of gas and other fields provides key technical support。
In traditional plastic coated pipe applications，Pipeline connection due to geological settlement、Small leaks are prone to occur due to factors such as temperature changes，The daily leakage rate of a single location is often lower than 1 cubic meter，Conventional manual inspections are difficult to detect，Over 10 million tons of water resources are wasted annually due to hidden leaks，Gas leakage poses significant safety hazards。Tianzhuo Pipe Industry's patented technology is achieved through innovative flange structure design，constructed “dual protection + Intelligent Monitoring” The security system：Open inner and outer double-layer annular grooves on the flange connection surface，The sealing ring of the inner groove achieves physical sealing，The outer groove is equipped with a monitoring module composed of a floating ball and a touch switch。When a small leak occurs，Water seepage or gas will enter the outer groove，Trigger the float to float up and touch the switch，The linkage alarm is 3 Sound and light warning within seconds，Simultaneously push the leakage location information to the operation and maintenance platform synchronously through the IoT module。
Industrial testing data shows，This technology is effective for 0.1 rise / The detection rate of small leaks in minutes reaches 100%，Shortened response time compared to traditional pressure monitoring 90%，And the cost of the entire device only increases the cost of a single tube 8%。currently，The patented product has been piloted and applied in the water supply network renovation project of Meixi Lake International New City in Changsha，Covering pipeline length up to 12 kilometer。During the pilot period，The operation and maintenance team proactively alerts and promptly handles the situation 3 Minor leakage at the location，Avoiding millions of maintenance losses caused by subsequent pipeline corrosion expansion。The Technical Director of Tianzhuo Pipe Industry stated that，2026 We will achieve comprehensive mass production of this technology in the coming year，Expected to drive a reduction in leakage rates in the water supply industry 15% above。
