Роторные буровые штанги

Роторные буровые трубы North Star изготавливаются с использованием соединительных элементов из высококачественной легированной стали 4145 HT и закаленной легированной стали, а также предлагаются варианты с использованием горячекатаных бесшовных углеродистых труб.
Варианты труб средней части корпуса: 4140
Сплав: Данная труба из легированной стали применяется в условиях жестких абразивных пластов в качестве решения, позволяющего замедлить износ средней части трубы, характерный для подобных геологических формаций. Физические характеристики, предел текучести, предел прочности при растяжении и твердость по шкале HRC данной легированной трубы обеспечивают более долговечную и износостойкую трубу в средней части по сравнению со стандартной бесшовной углеродистой трубой горячей прокатки.
ST52: Эта труба средней части корпуса обычно применяется в пластах с низкой абразивностью. Это горячекатаная бесшовная углеродистая труба.

WHY NORTH STAR

The Right Tube for the Right Formation

North Star Rotary Drill Rods are built around the drilling conditions that matter most. Alloy tube is available for hard, abrasive formations where mid-body wear is a key concern, while hot-rolled seamless carbon tube provides a practical option for less abrasive formations.
Tube selection is matched to formation abrasiveness, while welding and inspection processes are controlled to support consistent drill pipe performance.
01

Alloy Tube for Abrasive Formations

The alloy tube option is applied in hard, abrasive formations to help slow mid-body wear and provide greater durability and wear resistance.
02

Hot-Rolled Seamless Carbon Tube

This tube option is typically applied in less abrasive formations where a standard hot-rolled seamless carbon tube is a practical choice.
03

Friction & Submerged-Arc Welding

North Star offers both friction welding and submerged-arc welding processes for rotary drill pipe configurations.
04

In-House Ultrasonic Testing

Welds are inspected using in-house pipe ultrasonic testing as part of the manufacturing and quality control process.
MANUFACTURING & QC

Controlled from Tube Selection to Final Inspection

North Star controls the key processes that influence rotary drill pipe performance, from tube selection and welding to inspection. The result is a controlled manufacturing process for rotary drilling applications.
01 Tube Selection
Alloy or seamless carbon tube selected for the formation.
02 Tube Processing
Controlled manufacturing of the drill pipe body.
03 Welding
Friction or submerged-arc welding process.
04 Inspection
In-house pipe ultrasonic testing of welds.
05 Specification Control
Dimensions and thread requirements checked.
06 Custom Configuration
Rig, thread and wrenching requirements matched to the order.

Часто задаваемые вопросы

Rotary Drill Pipe: Common Questions

Clear answers about rotary drill pipe, sizes, specifications, tube selection and configuration.

What is rotary drill pipe?

Rotary drill pipe, also called rotary drill rods in some markets, connects the drilling rig to the drill string and transmits drilling loads. Selection depends on the rig, dimensions, threads and formation conditions.

What are the main rotary drill pipe types?

Common configurations include drill pipe made with alloy tube for hard, abrasive formations and hot-rolled seamless carbon tube for less abrasive formations. Welding can use friction or submerged-arc processes.

What are rotary drill pipe sizes and specifications?

Key specifications include drill pipe diameter, wall thickness, length, recommended thread and tube steel grade. North Star also offers additional diameters, wall thicknesses and thread types upon request.

How do I choose the right rotary drill pipe?

Start with the drilling rig make and model, drill pipe OD, length, wall thickness, pin and box thread configuration, wrenching requirements and formation conditions.

Can you supply rotary drill pipe for air rotary drilling rigs?

For specialized applications such as air rotary drilling, provide the rig model and required pipe configuration so North Star can review the appropriate specification and availability.

Can North Star manufacture custom rotary drill pipe?

Yes. Additional diameters, wall thicknesses and thread types are available upon request. Custom requirements can be reviewed based on the drilling rig and application.
