Viega 90730 – Frequently Asked Questions
1) What size pipe does the Viega MegaPress 90730 flange fit?
The Viega MegaPress 90730 flange is a 4 inch fitting, pressed onto 4 inch carbon or stainless pipe on the press end with the other end a flange face for bolted connections. If your line is a smaller diameter, this is the wrong size part.
2) Is the Viega 90730 a press fitting or does it thread or weld on?
Press on one end. The MegaPress 90730 uses a mechanical press connection, so no threading, no grooving, and no hot work on the pipe. That is the usual reason it gets chosen in occupied buildings where a welding permit is a problem. The flange end bolts to a mating flange, so you still need the gasket, bolts, and nuts for that side.
3) Is the Viega 90730 MegaPress flange stainless steel or carbon steel?
It is 316 stainless steel, the more corrosion resistant of the common stainless grades, which is why it gets specified for chilled water, compressed air, and industrial lines where plain carbon steel fittings would pit. Made in Germany.
4) What does Smart Connect technology do on a Viega MegaPress fitting?
Smart Connect is Viega's feature that deliberately leaks a small amount at an unpressed connection during test, so an installer can find the joint that was missed before the system goes into service. On a 4 inch flange in a plant room, that is the difference between catching one bad press at test and chasing it after startup.
5) What clearance do I need around the Viega 90730 flange in a tight mechanical room?
The fitting itself measures 4.835 x 9.055 x 9.055 inches. Add to that the swing and depth of the large-diameter press jaw or ring, plus bolt access on the flange face, when you are laying out against a wall or alongside another run.
6) Do I need anything besides the 90730 flange to make up the joint?
Two things are not part of the fitting. You need a press tool with the correct 4 inch MegaPress jaw or ring to make the press, and you need the flange gasket and bolt set for the bolted side. The fitting ships as the flange body only.
7) How much does the 4 inch Viega MegaPress 90730 flange weigh, and can one person handle it?
It weighs 13.881 lbs, so it is a two-hand lift and generally a two-person job once you add the press tool and jaw for a 4 inch press connection overhead. Plan rigging or temporary pipe support before pressing.
8) What is the Viega part number and UPC for the 4 inch MegaPress stainless flange?
Order it as Viega MegaPress 90730. The UPC on the carton is 691514907307. Quoting the model number is the safest way to avoid being sent a carbon steel MegaPress flange instead of the 316 stainless one.
