Integral Spiral Centralizer Caliber: 125mm

These Integral spiral centralizer downhole and drill string, the wear-resisting material on the surface of the work (i.e., taking positive) are commonly used surface carbide Mosaic column, set with a diamond surface complexes, wear-resistant surfacing electrode, and a variety of forms such as low temperature brazing carbide bar.
Integral spiral centralizer is made of high quality AISI 4145 h steel production and processing, and strict enforcement of SY/T5051-91 standard, material through the overall heat treatment, obtain excellent mechanical properties, can be to cold rolling thread, plating copper or phosphorus treatment. Mainly have the effect of stability of drilling tools in the process of drilling.
