Bend Radius
JT
JT30 drill pipes have a tested minimum bend radius of
155’ (44.2 m). This means that a 90-degree bend in
the bore path:
•
has a radius (A) of 155’ (44.2 m)
•
requires approximately 243’ (74 m) of drill pipe
(B).
AT
JT30 All Terrain drill pipes have a tested minimum
bend radius of 145’ (47.2 m). This means that a 90-
degree bend in the bore path:
•
has a radius (A) of 145’ (47.2 m)
•
requires approximately 228’ (69.5 m) of drill pipe (B).
AT Cobble
JT30 All Terrain cobble drill pipes have a tested minimum bend radius of 210’ (64 m). This means that a
90-degree bend in the bore path:
•
has a radius (A) of 145’ (47.2 m)
•
requires approximately 330’ (100.5 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.
