Product Description Products Details:Non-magnetic drill collar is a low-carbon high-chromium manganese alloy steel drill collar. It is made through strict chemical composition ratio and refinement. It has excellent low magnetic permeability and high mechanical strength. The non-magnetic drill collar is made of a low-carbon high-chromium manganese alloy steel. It achieves its mechanical properties through strict chemical composition ratio, refinement, and forging. It has excellent low magnetic permeability, high mechanical strength, excellent intergranular corrosion resistance cracking performance, and excellent wear resistance. When the magnetic field strength is 1×105/4π A/m, the relative magnetic permeability μr of the non-magnetic drill collar is ≤1.010. The magnetic intensity gradient along the inner hole of the non-magnetic drill collar at any distance of 100mm is ≤0.05 μT.Specification: ConnectionOD ID Overall LengthNC23-313 1/8"1 1/4"31ftNC31-414 1/8"1 1/2"31ftNC44-606 1/4"2 13/16"31ftNC42-626 3/4"2 1/4"31ftNC50-728"2 13/16"31ft6 5/8REG8 1/4"2 13/16"31ft7 5/8REG9 1/2"3"31ftFactory:Certificates:After-Services: 7/24 hours
