Pipe Wrap Around Guide — How to Mark a Square Cut on Pipe
C-Pi-D Pipe Wrap Guide: How to Mark a Square Cut on Pipe
A flexible wrap-around marking tool for scribing a dead-square cut line around pipe, tube and conduit, and for measuring the pipe's diameter or circumference from the printed metric and imperial scales.
Quick fixes: read this before returning
- "My line doesn't meet up when it goes around." The wrap isn't square to the pipe. Pull it tight and slide it until the edge meets itself exactly where it overlaps. When the edges line up all the way round, the line will be square.
- "It's too long for my pipe." That's normal. A bigger wrap works on any smaller pipe. Just let the extra overlap.
- "It won't reach around." Your pipe is bigger than the wrap's rated outside diameter. Check the size table below.
- "It curled or went soft." That's heat. Take it off before you cut, grind or weld.
Sizes: are these the right instructions for you?
Each wrap is sized by the largest outside diameter (OD) of pipe it fits. Working on bigger pipe, or need a spare for the van? Pick the size that covers the largest pipe you work on.
| Wrap | Fits pipe up to (OD) | Shop |
|---|---|---|
| 6" Pipe Wrap | ½" to 6" (152 mm) | View 6" wrap |
| 11" Pipe Wrap | 11" (279 mm) | View 11" wrap |
| 15" Pipe Wrap | 15" (381 mm) | View 15" wrap |
| 20" Pipe Wrap | 20" (508 mm) | View 20" wrap |
| 24" Pipe Wrap | 24" (610 mm) | View 24" wrap |

How to use it
Before you start
- You'll need a scribe, soapstone, a paint marker or a fine permanent marker.
- Clean off loose scale, grease and dust so the wrap sits flat.
Marking a square cut line
- Wrap the tool around the pipe at the cut position.
- Pull it snug and overlap the ends.
- Slide and twist until the edge meets itself exactly at the overlap. That's the only check you need: if the edges meet, the line is square.
- Hold it in place with a spring clamp or a hand on the overlap, and run your marker along the edge all the way round.
- Remove the wrap, then cut.
Measuring diameter or circumference
- Wrap the tool snugly around the pipe.
- Choose the scale you need: diameter or circumference.
- Choose your units: metric or imperial.
- Read that scale at the zero line. The zero line is the reference mark for both measurements. Where it lines up on the diameter scale gives the diameter, and where it lines up on the circumference scale gives the circumference.
Lining up the edges at the overlap is for marking a square cut line (above). For measuring, always read at the zero line.
Insulation and lagging
Use the same method on pipe insulation to mark a clean, square trim line.
Common mistakes
- Marking before the edges meet at the overlap, which makes the line spiral.
- Leaving the wrap on while cutting or welding.
- Buying a wrap smaller than the pipe. Always size to the largest OD you work on.
Heat
Mark, remove the wrap, then cut, grind or weld. A wrap left on hot pipe will soften and curl.
Looking after your wrap
Wipe it clean, then put it back in its convenient storage tube, or store it flat, out of the sun.
