Product Description

Special low-carbon stainless steel, developed by PDM independently, is adopted to manufacture the non-magnetic products. The raw material has the features of low magnetic conductivity, high intensity of mechanical character and excellent resistance of inter-granular stress corrosion cracking. PDM can manufacture all kinds of non-magnetic drill collars, non-magnetic HWDPs and non-magnetic high pressure resistance drill pipes according to API specifications or other standards. The specifications of non-magnetic drill collars are the same as the slick ones.
