PE112 is a polypipe material which is meant to be one step after PE100, due to its higher MPa (how the minimum required strength is measured), yet despite this, it is not always the better choice to PE100 as its maximum allowable operating pressure (MAOP) cannot be increased nor can the walls be made thinner like with PE100. This blog post explores this in more detail.
