IPS STAINLESS STEEL PIPE PRODUCTS
Stainless Steel Flange Solutions
Victaulic offers a variety of stainless steel flange adapters designed for directly incorporating
stainless steel flanged components into Victaulic’s stainless steel grooved piping systems.
Style 441
2 – 6"/50 – 150mm
Available with a variety of gasket materials to meet most service applications, Style 441 is
available in 2 – 6"/50 – 150mm sizes. The Style 441 flange adapter has integral end tabs that
facilitate assembly. Constructed from corrosion resistant Grade CF8M (316 equivalent) stainless
steel, the flange adapter is ideal for externally corrosive environments.
No. 445F and No. 445R
1¼ – 12"/32 – 300mm
All stainless steel flange adapter nipples No. 445F and No. 445R are supplied with either
ANSI B16.5 Class 150 slip-on stainless steel flange or ISO EN-1092-1 PN 10 and PN 16
weld-neck stainless steel flange. Victaulic offers No. 445F and No. 445R stainless steel flange
adapter nipples in sizes from 1¼ – 12"/32 – 300mm in both raised face and flat faced configurations.
In order to achieve Victaulic specified product performance, the proper Victaulic roll grooving
tool and corresponding Victaulic roll set must be selected. When roll grooving ANSI Schedule
5S or 10S Type 304L or 316L stainless steel pipe, a Victaulic manufactured RX roll set is
required. Review document 24.01 for more details on pipe preparations.

Style 441
VIC-FLANGE ADAPTER NOTES
1.Working Pressure and End Load are total, from all internal and external loads, based on Schedule
10S stainless steel pipe, roll grooved with Victaulic “RX” stainless steel rolls in accordance with
Victaulic specifications. Contact Victaulic for performance on other pipe.
WARNING: FOR ONE TIME FIELD TEST ONLY, the maximum Joint Working Pressure may be
increased to 1½ times the figures shown.
2.The Style 441 does not rigidly attach to the grooved pipe. Some axial, angular and rotation
flexibility of the pipe is to be expected.
3.The Style 441 is designed for use with Class 150 raised-face flanges, in accordance with ANSI
B16.5. When a Style 441 is used with a flat-faced flange, the raised projections on the outside
edge and around the mating holes of the flange adapter must be ground flush to the body. Refer
to the Style 441 Installation Instructions.
4.The Style 441 cannot be used, unless it mounts flush to the mating flange; therefore, flange
washers, or anything else that prevents flush mounting, cannot be used. Please use the No. 445F
or No. 445R.
5.The Style 441 must not be used as anchor points for tie rods across non-restrained joints.
6.The Style 441 must not be used against rubber coated surfaces or with wafer or lug-type valves,
or when the flange adapter does not mount flush with the mating flange. For those types of
applications, use a groove by flange adapter nipple, such as the No. 445F or No. 445R.
7.Because of the outside flange dimension, the Style 441 must not be used 90° to one another
on a standard fitting.
8.Area A-B noted in the accompanying drawing (page 2) must be free from gouges, undulations or
deformitities of any type for effective sealing
9.Style 441 Flange adapter gaskets must always be assembled with the color coded lip on the pipe
and the other lip facing the mating flange. The markings on the outside of the gasket must face
the Style 441 flange adapter.
10. WARNING: Depressurize and drain the piping system before attempting to install, remove, or adjust any Victaulic piping products.
