Drill Stem for Decoking Systems

Drill Stems

Saptora drill stems transmit water and torque from the rotary joint to the cutting tool. Their threaded design offers exceptional durability, with side-load strength four times greater than comparable welded stems.

The optional Scorpion FLS 600 drill stem installation tool enhances safety and reduces installation time, simplifying disassembly and reassembly compared to traditional labor-intensive methods.
