Petrorio Drilling Tools

Petrorio Drilling Tools manufactures high-quality Safety Clamps, designed to secure tool strings and flush surface tubulars during assembly or disassembly. These clamps prevent accidental dropping of the tool string if slips or elevators lose grip, ensuring safe operations on the rig floor.

Our multipurpose Safety Clamps are made from high-grade alloy steel, duly hardened and tempered for exceptional strength and durability. Each clamp undergoes rigorous quality checks, including ultrasonic testing and magnetic particle testing, to guarantee reliability under demanding drilling conditions.

Designed for versatile applications, these clamps can be used for running large-diameter surface casing, handling drilling risers and casing heads, or lifting pre-packed gravel liners. The multi-link design distributes pressure uniformly around the pipe, minimizing the risk of damage or crushing.

Safety Clamps are available in a wide range of sizes, from 2.7/8” to 36”, accommodating various tubulars and operational requirements.
