in water tube bent tube boilers tubes take from 2 to 4 bends. hence it become impossible to check the entire tube lenth for scle because of bends. then what methods can be used for this purpose? moreover , will it be save to make the ACID CLEANING of a bent tube w/t boiler each year?
thanx..........
