One-Rig Class Aligner: Where Three Oilfield Hose Circuits Line Up, and Where They Do Not
A rig specified at one pressure class does not take that class on all three flexible circuits. Pick the class you are working to and this aligner shows what each circuit can actually be supplied at, where the package breaks, and what that means for a combined enquiry.
