AI Technical Summary

Technical Problem

Existing pressure testing equipment cannot effectively test the pressure resistance of the half-section of the coupling, resulting in a risk of pipe bursting during use.

Method used

A pressure testing machine was designed. By setting a semi-circular pipe and a supporting plane on the pressure testing platform, pressure is applied to the connecting flange edge of the half-section using a pressure strip plate to form a sealed cavity. Pressure resistance tests are then conducted using a pressurized water source, making it suitable for half-sections of different specifications.

Benefits of technology

It enables stable and accurate pressure resistance testing of half-section couplings, is simple to operate, and is applicable to tee and four-way half-section couplings, reducing the risk of pipe bursts.
