About this product

Drill stems transfer the water and torque from the rotary joint to the cutting tool. Flowserve threaded drill stems are extremely durable and have a side load strength four times greater than comparable welded drill stem designs.

The optional Flowserve Scorpion FLS 600 Decoking System drill stem installation tool improves safety and reduces disassembly and reassembly time compared to labor-intensive traditional methods.

Flowserve’s decoking system is fully integrated. Watch these videos to see our individual components.
