Main Exhibits： The pipeline demagnetization machine, pipeline demagnetization and heating integrated machine, and demagnetization machine are mainly used to demagnetize pipelines during welding operations on oil and gas pipelines to ensure the integrity of the welding. The pipeline demagnetization and heating integrated machine is not only used for demagnetization but also for stripping pipeline anti-corrosion layers or heating pipelines. The pipe demagnetization machine can be used not only for online demagn
