Inquiry (采购产品): Pressure Cleaning Service We are a chemical mfg. company and have some evaporator tubes that have a build up of calcium silicate. We have used a high pressure with water to clean the tubes, however, this only clears a hole doesn't remove the build up. Do you or can yo0u recommend anyone that does pressure cleaning with a chemical such as hcl? Thanks for your assistance. **** Hidden Message ***** Phyllis King 28016 Company: FMC E-mail: phyllis_king@fmc.com **** Hidden Message ***** phyllis_king@fmc.com
