No, this camera does not have any chemical resistance rating, it was designed for use on plumbing and sewer applications. No, this camera will not have enough light to illuminate 12" or 40" pipes. You may look at a different option - we have an Anaconda Sewer camera with a Pan-and-tilt head, Magnum and Trogloprobe camera systems as well as a few pipe crawler models.
