TBSU (ТБСУ) universal steel boring pipes with welded-in locks
TBSU (ТБСУ) are applied at surveys and exploration on solid mineral deposits and water for well drilling by core barrel and full hole drilling with the use of hard-alloy and diamond crown bits, bore bits of all types, including with the use of hydraulic and pneumatic downhole hammers; at engineering-geologic surveys; in construction.
Boring depth: up to 2000 m.
