Both types of pipe material are getting fairly expensive, so many water pipes these days are made of polypropylene plastic. In fact, iron is only used for large size pipes . . . usually underground, but not always. Most modern underground pipes are made of PVC, or polyvinyl-chloride. ABS or acrylo-nitrile-butadiene-styrene is often used for non-pressure pipes like drainage pipes, for instance.
MANY things. Duct tape can seal cracks in ducting - it's original purpose. It can join different pipes and seal them. It can be used to attach a number of things together.
