📉 Are Your Drill Pipes Costing You More Than They Should? 3 Tips to Extend Their Lifespan.
In high-pressure Down-The-Hole (DTH) drilling, your drill string takes a massive beating from abrasive rock walls and constant mechanical stress. If you are replacing pipes too frequently, your cost-per-meter is taking an unnecessary hit.
Did you know that a few proactive maintenance steps can significantly extend the operational life of your drill string? Here is how you do it effectively:
🔄 1. Replace Your Saver Sub Proactively
The saver sub takes the brunt of the make/break threading cycles. If you let a saver sub wear down too far, it will cross-thread and permanently damage the threads of every single new drill pipe it touches. Swapping out this low-cost component every 1 to 3 months is the cheapest insurance policy for your expensive drill string.
🛢️ 2. Never Skip Thread Lubrication
High-frequency impact friction is the enemy of steel. Always ensure generous application of high-quality thread grease during rod changes to prevent galling, metal-to-metal seizing, and premature thread wear.
⚙️ 3. Upgrade to Friction-Welded Pipes
The weakest point of any drill pipe is usually the joint. At Drill Rod Specialist (DRS), our DTH pipes are manufactured in Chamdor using advanced solid-state friction welding. Because we join the tool joints to the mid-body without filler metals, the result is a seamless bond with incredible bending resistance that outlasts standard welded pipes.
Maintaining your string doesn't just save money; it prevents catastrophic down-hole failures.
