| A METHOD OF AND DEVICE FOR PIPELINE WALL VACUUM TREATMENT |
| In the newly-developed method, vacuum chamber is installed on a pipeline section or a welded joint and the closed volume is depressed. After charge plasma have effected a pipeline section or a welded joint and adjacent area, a coating is applied to the pipeline wall or welded joint. The chamber is then de-vacuumed and, if required, protective coating is additionally applied under ambient pressure. Thereafter, arc electrodes, a protective coating application unit and a laid-on vacuum chamber are removed to the next pipeline section which is processed in a similar way. |
