DESIGN CONFIGURATIONS

rocketplate-home-1A

1-PIECE ORIFICE PLATE

Our 1-piece RocketPlates can be fabricated with or without a hard coating on the orifice ID. Bare metal plates are ideal for non-abrasive fluids, while hard coatings are applied to plates going into abrasive slurries with larger orifice diameters.

RocketPlates can be coated with any welded hard overlay, such as Stellite 6, Tungsten Carbide (applied via ‘PTA’), Chrome Carbide, Eutectic Coatings, Etc. These materials are applied to the orifice ID and onto the upstream and downstream faces.

3-PIECE ORIFICE PLATE W/ CARBIDE INSERT

RocketPlates with sintered carbide wear inserts are designed for abrasive slurries. The carbide inserts are extremely hard, providing unparalleled wear resistance. Once the inserts do wear out, they can be replaced within minutes.

Our most common carbide materials are ‘Sintered Tungsten Carbide’ and ‘Sintered Silicon Carbide’ (aka: Ceramic). These materials can be manufactured into any shape, allowing RocketPlate engineers to provide the best possible design.

ORIFICE PLATE W/ RUBBERIZED INLET

Rubber inlays are typically specified when slurry applications contain large particles (such as rocks). A thick rubber layer protects the inlet side of the RocketPlate; while the downstream side houses a sintered carbide insert or welded hard coating.

These orifice plates have wider face-to-face dimensions, and are the most heavy-duty RocketPlates we manufacture. We only recommend these designs for the most severe slurry applications.
