Mining Drilling Tools Sub Adapters Connection Forging Processing Type
Application
Sub & adapters are used to connect two different types or sizes of threads.
Subs and Adaptors are manufactured from quality heat treated alloy steel for durability and strength.
Tube Technologies can manufacture any type of sub adapter. Made from 4142 heat treated alloy which is the hardened to 32 – 36 Rockwell provides maximum strength as subs are hardened to 32-36 Rockwell C substantially stronger then the traditional commercial bar stock. Breakout (custom flats or lugs) are available on request. Our extensive array of thread gages allows you to have complete customization of any sub adapter.
Available Adapter Configurations:
Often we come across undefined tool joints. The thread identification is normally stamped on the tool joint.
If that stamp is worn or is not present you need specific information to determine the tool joint identification.
The way to define the pin tool joint (The box tool joint is hard to measure and measurement has often lead to errors) is to measure:
A. The diameter of the base of the pin where it meets the sub body (shoulder).
B. The thread length. Measured from shoulder to the end of the tool joint.
C. The number of threads per inch - put the 0 mark of a ruler on the center
of the first thread, don't count that thread, then count the threads to the one inch mark
D. The thread form (taper, square, acme, special, etc.)
E. The material O.D. - this may differ within threads, but is a cross check.
