Safe-Lock · optional

The weld-free
connection.

A mechanical coupling that replaces welding at critical drill-string connection points — reversible, modular and strong.

How it fits

Locked in seconds.
Never welded.

Clamp halves lock the top and bottom subs to the absorber — no welding to the rotary head bull shaft or the top adapter.

  • No heat-affected zones in the steel
  • Quick, reversible assembly and inspection
  • Lighter and safer on site — no hot work

Why no-weld matters

Stronger steel.
Safer sites.

Welding a shock absorber to the bull shaft weakens the steel and turns every service into hot work. The Safe-Lock removes both problems.

01Weld-free integration

No welding between bull shaft, shock absorber and top sub.

02Structural integrity

No heat-affected zones, so the steel keeps its original strength.

03Modular maintenance

Rapid inspection and replacement without destructive cutting.

04Operational safety

Removes fire risk and hazards of welding on site.

05Universal fit

Optional on all Samavich rotary and DTH shock absorbers.
