The maximum amount of compensation promised each wave: Full-△ α = ± 24mm Half-△ α = ± 12mm. Ash board: less dust on duct pipe sleeve compensator can not use models of dusty gray board flue files should be used. To reduce the number of nodal sleeve compensation offer bellows should be considered cold drawing 50 percent.
