API 5D
DRILL PIPES
Steel pipes with upset ends and weld-on tool joints, designed for construction/repairs of oil and gas wells and of geological prospecting.
Pipes may be supplied with API monogram according to API 5D (License No.5D-0056).
The specifications of drill pipes' grades, upset types and range of size are given in Table 1. The requirements to chemical composition are given in Table 2. The mechanical properties are given in Table 3. The range groups are given in Table 4. The replacement possibility for lock threads' specifications according to API and GOST standards is given in Table 5. The replacement possibility for grade's specifications accoding to API and GOST standards is given in Table 6.
