Track Ring
Standard track rings come in two varieties. Two
segment tracks and four segment tracks. Two
segment tracks start at an 8 inch diameter and in-
crease in size by 2 inch increments up to 28 inches.
Four segment tracks start at 30 inches and increase
in size by 4 inch increments up to 64 inches. Spe-
cial sizes are available upon request.
Each segment will have 2 end caps; one threaded
one with bolts.
Track rings will have cross braces evenly distribut-
ed between the end caps. The number of cross
braces per segment is determined by the size of the
track ring:
x
8” track rings have 3 cross braces
6 per track ring
x
10” -3 2” track rings have 5 cross braces
10 per track ring
x
32” and above sizes will vary
Not all cross braces require shoes.
Track shoes come already installed on the track
ring (see Figure 2
– Shoe Placement). Figure 2 is
an example of a 2 segment track ring.
Pipe dimensions vary by size, type and application.
A 12” track rings is designed for a 12” outside d i-
ameter pipe.
Do not use different serial number track rings of the
same size.
Track rings are serialized by size and engi-
neered to fit together, Tracks of the same
serial number only join the correct way.
