Style 809N High-Pressure Coupling for Ring Systems
IMPORTANT INFORMATION
WARNING
• Depressurize and drain the piping system before attempting to install, remove, adjust, or maintain any Victaulic piping products.
• Wear required personal protective equipment during the welding process, and follow all jobsite regulations regarding welding safety.
• Wear safety glasses, hardhat, and foot protection during the coupling installation process.
• DO NOT attempt to install this product on pipe that is grooved (roll or cut) or that contains a weld bevel. Pipe ends shall be square cut.
• DO NOT attempt to install this product with rings supplied by other manufacturers.
Failure to follow these instructions could result in death or serious personal injury and property damage.
The Style 809N High-Pressure Coupling for Ring Systems is designed for installation on pipe that is prepared with rings supplied by Victaulic. Refer to Victaulic publication 15.03 for allowable pipe materials and joint performance.
PIPE PREPARATION/RING ATTACHMENT
"S" Max.
1a. SQUARE CUT THE PIPE ENDS: The maximum allowable tolerance from square­cut pipe ends (“S” dimension shown) is
⁄ inch/1.6 mm. This is measured from
the true square line.
1b. INSPECT PIPE ENDS PRIOR TO RING ATTACHMENT: The outside
surface of the pipe ends (approximately 2 inches/51 mm back from the ends) shall be smooth and free from indentations and projections. All oil, grease, loose paint, dirt, and cutting particles shall be removed.
2a. INSTALL RING ON PIPE: Spread the ring apart using appropriate tooling at the ring opening (refer to the ring detail on page 2). Slide the ring over the pipe end.
2b. POSITION RING: Remove the tooling and position the ring at the required distance (refer to page 2 for the “B” dimension, which is the required distance from the edge of the ring to the pipe end).
NOTICE
• Use Victaulic ring clamps to hold the rings at the appropriate location on the pipe during tack welding.
Ring Clamp for
4-inch/114.3-mm Pipe
Ring Clamp for 6-inch/168.3-mm and 8-inch/219.1-mm Pipe
Ring Clamp for
10-inch/273.0-mm Pipe
2c. CLAMP RING IN POSITION: Hold the ring in position by applying a ring clamp at three locations around the pipe circumference. DO NOT cover the butt ends of the ring with a ring clamp.
2d. TACK WELD THE RING: Tack weld the ring to the pipe in enough locations so that the ring does not shift out of position when the ring clamps are removed.
2e. REMOVE RING CLAMPS AND COMPLETE WELD PROCEDURE:
Remove ring clamps. Weld around the entire circumference on both sides of the ring. Refer to page 2 for complete weld requirements.
3a. INSPECT RING: The ring shall not contain any weld splatter or arc strikes.
3b. INSPECT WELDS: Weld size and geometry shall meet the requirements on page 2.

NOTES:
1. Victaulic ring to be supplied unpainted with a rust-inhibiting coating applied. Check rings to verify that all oil, grease, and dirt is removed prior to welding.
2. Victaulic ring material: ASTM A108 Grade 1018, cold-rolled carbon steel
3. Weld metal: E70XX or greater
4. This area shall be free from indentations, projections, and weld splatter to ensure a leak-tight seal for the gasket. All oil, grease, and dirt shall be removed.
5. Pipe material: Refer to Victaulic publication 15.03, which can be downloaded at victaulic.com
6. Pipe thickness: Refer to Victaulic publication 15.03, which can be downloaded at victaulic.com
7. Weld procedure by others
8. Take precautions during welding to keep heat buildup low. Excessive heat buildup can result in ring diameter shrinkage after cooling to ambient temperature.
9. Final weld shall not extend past the edge of the ring. Excess weld material will compromise the joint.
