Any program that does normalisation will increase the volume without adding any problems, however it works on the complete file, so if the disturbances you mention were recorded along with the pipe sound then these will be increased as well.
If it is the latter your having problems with, then you will need more advanced knowledge to be able to use an editor to remove them, so I am afraid you will need to get studying sampling and mastering to clean it up. (There is no software that will do it by a click of a button)
