The increased diameter to 4" allows you to increase the volume of liquid supply.
The bimetallic cylinder is used on the installation of HDD Vermeer 50x100, 80x100, Vermeer 100x120. 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:
- They are 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.
Best value for money!
