Introduction
When it comes to oil exploration, borewell drilling, and geotechnical investigations, selecting the right drilling tube type is critical. The type you choose affects drilling depth, strength, and tool compatibility. In this guide, we’ll explore the different types of drilling tubes, their construction, and ideal applications.

What Are Drilling Tubes?
Drilling tubes—also referred to as drill rods or drill pipes—are tubular steel components used to connect surface equipment to the drill bit. They must withstand axial tension, internal pressure, and torque, making their material and type crucial to drilling performance.
Common Drilling Tube Types
1. Seamless Drilling Tubes
- Made via hot rolling without weld seams
- Excellent for high-pressure, high-stress drilling
- Typically conform to API 5DP, EN 10216-2, or IS 4270
- Used in: Oil & gas, geothermal, deep borewells
2. Welded Drilling Tubes
- Formed by welding a steel strip into a tube
- Suitable for shallow or low-stress drilling
- Economical compared to seamless types
3. Heavy Weight Drill Pipe (HWDP)
- Intermediate between drill collars and drill pipes
- Adds weight and stability to the drill string
- Reduces fatigue in the transition zone
4. Drill Collars
- Heaviest component in a drill string
- Used to apply weight on the drill bit
- Typically made of non-magnetic alloy or stainless steel
5. Double-Shoulder Drill Pipes
- Features dual shoulders for enhanced strength
- Ideal for high-torque and deep drilling conditions
Classification by Use
| Type | Application Area |
|---|---|
| Borewell Drilling Tubes | Domestic and agricultural use |
| Oil & Gas Drill Pipes | Deep onshore/offshore wells |
| Geothermal Drilling Tubes | Heat exchange & deep wells |
| Mining Drilling Rods | Rock coring & mineral testing |
Specifications to Look For
- Outer Diameter (OD): 2 ?” to 6 ?”
- Length: Ranges from 6 m to 13.5 m
- Wall Thickness: Light (6–8 mm) to heavy-duty (14+ mm)
- Material Grades: E75, X95, G105, S135
- End Connections: Pin & Box, NC, DSTJ, IF

How to Choose the Right Drilling Tube Type
- Project Depth: Use HWDP or collars for deeper wells
- Drilling Environment: Opt for seamless tubes in high-pressure, corrosive zones
- Budget: Welded tubes are cheaper but not suited for deep/high-torque operations
- Torque Requirement: Double-shoulder designs offer better torque resistance
