The maximum amount of compensation promised each wave: Full-△ α = ± 24mm Half-△ α = ± 12mm. Ash board: less dust on duct pipe can not use bellows compensator, for dusty flue gear gray board should adopt. To reduce the number of nodal bellows should be considered cold drawing 50 percent. Corrugated compensation for co-sectional area less than 4.6 square meters and a smoke duct shape and size, but there is more than one side is less than 1.5m 0.6mm occasions. Full-scale high bellows together for all of the smoke duct. In the weld flange joints smear foaming agent concentration of 10% or soapy water. 1% of ammonia gas in the test medium, corrugated compensation, etc. affixed wider than the outer seam weld 2Omm of paper, by observing the color changes to determine whether the leak. Submerged inspection. For the size of small bellows rotating compensator, usually checking it sank in the pool, according to the presence or absence of bubbles emerge, determine whether the tight bellows compensator.
