Notes
Pipe sizes are nominal. The weight of the assembled pipes is calculated on the basis of the nominal sizes.
The above data are given for reference. The parameters are calculated on the basis of the minimal yield strength of the aluminum alloy for the main section of the pipe body. Upon customer request, the pipes can be manufactured:
- with the modified geometrical parameters and threads;
- with 18-degree taper at the coupling with drill collar recess;
- with the extended tool-joint able to be re-threaded.
