The bimetallic liner is used on installations of HDD Vermeer 36x50s2, Vermeer 50x100a, Vermeer 80x100, Universal. It has an internal steel sleeve with a high chromium content, which significantly increases the service life due to a denser crystal lattice of the internal working surface.
Minimal porosity-reduces friction, increases the service life of the piston compared to other metals.
Advantages
- Manufactured using the latest advanced technologies by centrifugal casting
- Extended service life due to increased resistance to abrasive and corrosion wear
- Special multi-hour quenching and high content of alloying components on the working layer (molybdenum, nickel, chromium)
- High hardness 65-67 HRC (stainless steel hardness 35-40HRC) that when using highly abrasive drilling mud, it is especially important
- to reduce the downtime of equipment due to the extended service interval
- and the extended service life of pistons
In comparison with analogues made of stainless steel and other alloys, the service life of the bimetallic sleeve is increased up to 2, 3 times at the same product cost.
