PRODUCT SELECTION

How to Choose Drill Pipe & Drilling Tools

Choosing a drill pipe supplier starts with a clear technical specification. Use these checkpoints to narrow the product range and prepare a useful enquiry.

Drilling Method & Application

Identify HDD, rotary, DTH, reverse circulation or water well drilling. Describe the intended work and ground conditions so the product family can be selected first.

Rig & Operating Requirements

Provide the rig make and model, required pipe length and operating requirements. For HDD projects, include the bore profile and the applicable bend-radius requirements.

Dimensions & Connections

Specify outside diameter, wall thickness, length, and pin and box thread details. For RC drill pipe, include inner and outer tube dimensions and sealing interfaces.

CONFIGURATION & QUOTATIONS

From Product Search to a Defined Specification

Whether you need HDD drill rods, mining drill pipe or water well drilling tools, a complete enquiry helps identify the right configuration and avoid connection mismatches.

Drawings & Part Details

Send drawings, existing part numbers or sample details. Define the mating connections and any wrenching or interface requirements, especially for adaptor subs and replacement components.

Quantity & Delivery Requirements

State the required quantity, delivery destination and target date. Request current pricing and availability against the exact specification, rather than a general product name.

Custom Requirements

For custom drill pipe or drilling tools, describe the required dimensions, connections and inspection requirements. Additional diameters and lengths can be reviewed on request.

FAQ · DRILL PIPE & DRILLING TOOLS

Product Range, Selection & Purchasing Questions

What drill pipe and drilling tools does North Star supply?

The product range covers three series: HDD trenchless drilling, mining and construction, and water well drilling. Products include forged and welded HDD pipe, HDD downhole tooling, rotary drill pipe, DTH drill rods, reverse circulation drill pipe, API water well drill rods and adaptors.

How do I choose between HDD, mining and water well products?

Start with the drilling method and application. HDD products support horizontal directional drilling; the mining range includes rotary, DTH and RC products; the water well range includes API drill rods and adaptor subs. Confirm the exact pipe, tooling and connections against your rig and drilling system.

Are drill rods and drill pipe the same?

Terminology varies between drilling methods and suppliers. A product name alone does not establish compatibility. Use the dimensions, construction, thread details and part specification to identify the required component.

Do you supply both forged and welded HDD drill pipe?

Yes. The HDD series includes forged HDD drill pipe and welded HDD pipe, together with downhole tooling. Compare the detailed product specifications with your rig requirements and bore design before selecting a configuration.

Does the mining range include reverse circulation drill pipe?

Yes. Reverse circulation drill pipe is listed alongside rotary and DTH products in the mining and construction range. For an RC enquiry, provide the inner and outer tube dimensions, connection details and required sealing interfaces.

What information is needed for water well adaptors?

Specify the adaptor diameter, box thread, pin thread and required length. Include wrench-flat requirements and drawings or mating-part details. Lengths and wrench flats can be requested with your enquiry.

Can I request custom drill pipe sizes or connections?

Send the required dimensions, thread details, drawings or sample information for review. The team can assess the requested configuration and confirm manufacturing scope, availability and quotation details.

How can I request drill pipe prices or a quotation?

Provide the product series, rig make and model, pipe dimensions, thread connections, quantity and delivery destination. Include drawings and special requirements where applicable so pricing can be prepared for the specified product.
