Technical Review Scope
Configuration and Quotation Guidance
76 mm DTH drill-pipe configuration inquiry. This page records an API 2-3/8 REG connection reference and 1,000, 1,500, 2,000 and 3,000 mm length references. Those references do not by themselves define a complete drill-string configuration.
Compatibility notice: a pipe described as API 2-3/8 REG must not be treated as a direct mate to a top sub described as T48×10. CIR90 naming and 76 mm pipe outside diameter do not prove compatibility. A match may be stated only when a controlled same-thread, alternate-top-sub or crossover drawing identifies both interfaces and its revision is included in the quotation.
Configuration identity
PFM-DTH76-238-1000, PFM-DTH76-238-1500, PFM-DTH76-238-2000 and PFM-DTH76-238-3000 are length inquiry references, not complete orderable SKUs. They do not lock wall, bore, joint geometry, material, weight, operating condition or drawing revision.
Buyer inputs
- Pipe outside diameter and requested length.
- Current thread reference and photos or drawings of both threaded ends and shoulders.
- Rig rotary-head or saver-sub interface and hammer top-sub interface.
- Hole and depth requirement, compressor or air requirement, rig torque, pullback and operating condition.
- Quantity, destination and any inspection or packing requirement.
Engineering and quotation outputs
Before technical approval, the quotation drawing must return wall, bore, joint geometry, make-up and overall length, wrench flats, thread and shoulder details, material and heat-treatment basis, mass, allowed operating conditions and drawing revision. A buyer may submit “not sure”; the engineering outputs must not be guessed by the buyer.
Construction boundary
Joint construction, pipe-body material, heat-treatment basis and weld process are controlled quotation and drawing items; they are not defined by this inquiry page.
Inspection and records boundary
Any weld inspection or NDT method, sample or batch scope, acceptance criteria and report requirement must be expressly accepted in the quotation or purchase order; none is included by default.

Compatibility and Required Interfaces
DTH hammer top sub
API 2-3/8 REG
Mating thread, shoulder and airflow path
Provide hammer make/model or top-sub drawing.
DTH Drill-Pipe Configuration
Threaded Torque and Airflow Path
The box × pin joints transmit rotary torque while the internal bore carries compressed air to the DTH hammer.
Buyer value
A correctly matched connection and bore support joint life, airflow and stable make-up across the drill string.
Selection condition
Confirm thread gauge, shoulder dimensions, wall, bore, make-up practice and mating components.
Application Scenarios
- DTH production drilling
- Quarry and mining blast holes
- Water-well and foundation drilling

Frequently Asked Questions
Is 76 mm outside diameter enough to confirm compatibility?
No. Also confirm API 2-3/8 REG box/pin orientation, joint and shoulder dimensions, wall, bore, length, rotary-head or saver-sub connection, and hammer top sub.
Can you quote a length outside 1–3 m?
Yes, as a drawing-controlled configuration. Provide the required finished length, rig/hammer interface, handling limits, quantity and delivery country.
Matched Hammer and Rotary Interfaces
A complete 76 mm DTH string combines the rotary head or saver sub, API 2-3/8 REG drill pipe, matched hammer top sub and bit.
