Plan Bore Path
JT60 Power Pipe drill pipes have a tested minimum
bend radius of 170’ (57.8 m). This means that a 90-
degree bend in the bore path:
•
has a radius (A) of 170’ (57.8 m)
•
requires approximately 267’ (81.4 m) of drill pipe (B).
JT60 Power Pipe Forged drill pipes have a tested
minimum bend radius of 168.7’ (51.4 m). This means that
a 90-degree bend in the bore path:
•
has a radius (A) of 168.7’ (51.4 m)
•
requires approximately 265’ (80.8 m) of drill pipe (B).
NOTICE: Bending drill pipe more sharply than recommended will damage the pipe and cause failure
over time.
•
If bend radius is reduced, drill pipe life is reduced.
•
If bend radius is increased, drill pipe life is increased.
IMPORTANT: Use the charts on the next page to keep bends within safe limits.
