UHP Water(36,000 -40,000psi) does not affect the structure of steel substrate and does not create a new or modify an existing profile. With very thin steel piping, (less than 3/64 of an inch) there is the potential that it could slightly 'peen' the surface. In summary, there is really no minimum wall thickness requirement for UHP water on steel piping.

What is the minimum wall thickness on piping that UHP can be used with?

how much of an issue is flash rust, and can a water jetted surface be coated without a dry abrasive blast?
