AI Technical Summary

Technical Problem

In the prior art, water-soluble paper and tape are used to seal both ends of the pipe during pipeline welding, which is complicated to operate and increases the operating cycle, and the sealing material cannot be reused, which increases the cost.

Method used

The inflatable fixing plate, connector, sealing assembly and fixing assembly are used to fill the pipe with argon gas through the inflatable fixing plate. The sealing assembly and the inflatable fixing plate are removably connected, and the sealing sponge and sealing ring are used for sealing and noise absorption.

Benefits of technology

The installation and disassembly of the inflatable device is simplified, argon leakage is avoided, sealing sponge noise absorption reduces noise pollution, and the plug can be reused, reducing waste and usage costs.
