Non-magnetic flex drill collars
Non-magnetic flex drill collars are mainly used in horizontal directional drilling systems for tunnels in petroleum coal mines. Compared with Non-magnetic flex drill collars which is made of beryllium copper, the advantages of special alloy Non-magnetic flex drill collars are as follows: (1) Non-magnetic: It has the characteristics of non-magnetic. Under the condition of 20 Oersteds, its permeability is 1.00005-1.0001 H/m, and it will not be magnetized in a strong magnetic field; (2) Low den... -

Non-magnetic drill collars
Non-magnetic drill collars are one of tools for oil and gas exploration, drilling and well drilling. In the process of drilling, the drilling tool is often magnetic and has a magnetic field, which affects the magnetic measuring instrument, then we cannot get the correct measurement information of the wellbore. The use of non-magnetic drill collars can creat a non-magnetic environment and has the characteristics of drill collars in drilling. A considerable number of non-magnetic drill collar ... -
Non-magnetic pipes
Non-magnetic pipes are forged and processed from non-magnetic round bars, which can be further processed into drill pipes, drill collars, suspensions and other products. Our company have two grades of non-magnetic pipes,P530 and P550. Our materials meet all the performance indicators on the market and reach international standards. For forging, the 1800T precision forging machine is adopted, hot forging first and then warm forging, we strictly control the temperature and deformation of forgin... -
Non-magnetic round bar
Corrosion resistance requirements: all non-magnetic products can pass the corrosion test specified in practice e of American material test standard a 262. Non magnetic: relative Permeability: max. 1.005 Hot spot / field gradient: max. 0.05 μ T Special treatment inner diameter: roller polishing.(after grinding the roll, a compression layer is formed) The advantages are as follows: increase corrosion resistance; Increase the surface hardness of the hole to HB400 and the surface finish of the h... -
Non magnetic drill collar
Non-magnetic steel is made of low-carbon high chromium manganese alloy steel having a good low magnetic permeability, high strength mechanical properties, excellent crystal corrosion resistance and excellent wear resistance. The relative magnetic permeability μr ≤ 1.010 of the non-magnetic steel, the inner hole of 100 mm is ≤0.05 μt.
