Sell Non-Magnetic Drilling Collars

Description

Our products have been granted Certificate of Authority to use the Official API Monogram with license number *******2, ISO***1:***0 Certificate of Quality Management System and ISO****0 Certificate of Occupational Health and Safety Management System.

Strict control of chemical composition and low temperature forging guarantee the excellent mechanical properties of our non-magnetic products.
Tensile strength is ****0 percent higher than the requirement of API Spec **1.
Minimum Brinell Hardness is above **5 and minimum impact values is over **0 Joules.
Our non-magnetic products are highly corrosion-resistant, which greatly extends the service life of drilling tools in a corrosive atmosphere.
The maximum relative magnetic permeability of non-magnetic tools can be controlled to less than 1.**5 (API standard 1.*1), which increases the accuracy of measurements taken during directional drilling.
