Viega 84870 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 84870 flange fit?
The 84870 MegaPress flange is a 2 inch fitting, sized for 2 inch carbon steel pipe. Overall it measures 6.142 x 4.197 x 6.142 inches and weighs 5.907 lbs, which is worth knowing if you're working in a tight chase or hanging it off existing supports.
2) Is the Viega 84870 MegaPress fitting copper or steel?
Carbon steel. The 84870 is built for black iron / carbon steel pipe systems, not copper. If your line is copper you want a ProPress fitting instead, and stainless lines need a stainless press fitting. Mixing fitting material to pipe material is how you end up with a galvanic problem at the joint.
3) Does the Viega 84870 need to be threaded or welded on?
Neither. It is a press connection, so the 2 inch carbon steel pipe goes into the fitting and you crimp it with a press tool and the matching MegaPress jaw or ring. No threading, no torch, no hot work permit.
4) Can I use the Viega 84870 to tie pressed steel pipe into a flanged pump or valve?
That's exactly what it's for. One end presses onto 2 inch carbon steel pipe, the other is a flange face you bolt to a flanged pump, valve, strainer or piece of equipment. It's the transition point between a pressed run and bolted equipment, so you don't have to thread or weld a companion flange.
5) What is Smart Connect on the Viega MegaPress 84870, and why does it matter on a pressure test?
Smart Connect is the feature that makes an unpressed joint leak on purpose during test, so you find the fitting you missed instead of finding it after the walls close. On a large riser or a long run of 2 inch steel it's the reason crews press first and test second with confidence.
6) Do I need anything besides the 84870 flange to make the joint?
Yes. The flange itself is the fitting only. You supply the press tool and the 2 inch MegaPress jaw or ring, plus the gasket, bolts and nuts for the flange face when you bolt up to the mating flange, pump, or valve. Budget those separately.
7) What part number should I put on the submittal for the 2 inch MegaPress carbon steel flange?
Specify Viega part number 84870, described as MegaPress flange, carbon steel, 2 inch, with Smart Connect. That MPN is what your supplier and the engineer's submittal reviewer will both be matching against. It is made in Germany.
