non-magnetic drill collar

We are supplier of high-quality Non-magnetic drill collars used in oil and gas drilling operations worldwide. We will present to you

 the standards, material selection, and the types we can offer in the field of petroleum equipment. you can obtain drilling and casing solutions.

Our products are designed and constructed according to API Spec 7-1 and comply with relevant international standards such as 5DP and NS-1, whose body 

design provides thick, premium drill collar wall construction for durability and resistance to cracking or twisting. The rods feature high-strength threaded box 

and pin connections to reliably transmit torque and axial loads without failure.

We utilize high-strength non-magnetic alloys including P530, P550, and P650 to withstand high pressures and temperatures in hatsh downhole environments.

 Our non-magnetic material properties prevent interference with MWD tools for accurate wellbore positioning and surveying, and size from 3 1/8" up to 11", 

it is refined with strict chemical composition control, specially forged to achieve high strength mechanical properties and low magnetic permeability, excellent

 intergranular corrosion cracking resistance, and wear resistance.

We provide multiple API7-1 Non-Magnetic Drill Collar types including spiral, and slick collars. Spiral collars reduce sticking tendencies in horizontal and highly

 deviated wells. Slick collars allow for higher rotation speeds. Custom options and proprietary alloys are available. Technical parameters are available.
