"S" Max.
1a. SQUARE CUT THE PIPE ENDS: The
maximum allowable tolerance from square-
cut pipe ends ("S" dimension shown) is
1/16
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).

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.
