In the oil and gas industry, extensive lengths of connected pipes extract and transport substances across long distances. Threaded together, this series of adjoined pipes forms a drill string. These threaded connections between drill strings and pipe sections must maintain exceptional strength and durability, especially given the harsh conditions of these applications. Using cold root rolling techniques, industry professionals can enhance these connections.

In high-pressure, high-saturation, and/or high-corrosion environments, the wear and tear of pipeline components is inevitable. By employing cold root rolling (CRR) after thread rolling operations on pipe thread connections, oil and gas industry professionals reduce the damaging and degrading effects of the environmental factors acting on them, increasing their durability and overall service life.

Your drill string is your lifeline. It's a critical component of your business and it needs to be in operation if you want to make money. The failure of offshore drilling connections is an expensive mistake, costing upwards of $250,000 per day. It's highly unlikely such a problem would be repaired in a single day, so if the drilling rig is down for the average of six days it will cost at least $1.5 million.

What is Cold Root Rolling?
Cold root rolling is the process of burnishing the root radius of a previously cut thread, in a Rotary Shouldered Connection or thread profile. A hardened roll, similar in profile to the thread being manufactured, is placed in contact with the root radius of the tapered thread, and pressure is applied to force the roller to penetrate into the cut surface of the root radius, displacing and cold-forming the thread material. This deformation cold-works the material, imparting an improved surface finish and compacts and displaces the grains of the root material.
