AI Technical Summary
Existing pressure testing devices for circumferential welded pipes suffer from problems such as welding deformation, complex processes, high costs, low efficiency, poor adaptability, and poor stability.
A pressure testing device was designed, comprising a test platform, a welded pipe fixing device, a lateral drive device, and a pressure testing device. The device utilizes tie rods, guides, and seals to enter the welded pipe under lateral drive, forming a seal. Pressure testing is then conducted through a pressure medium supply device, achieving automated assembly and disassembly.
This technology enables mass pressure testing of welded pipes, reducing deformation and processing time, lowering costs, improving adaptability and stability, and simplifying the process.
