Orifice Plate Body: Temperature Range -20°C to 150°C

Component Specifications

Definition

A critical flow control component designed specifically for starch slurry applications, featuring a precisely calibrated orifice that creates a differential pressure for flow measurement and regulation. The body provides structural integrity and mounting interface for installation in pipelines, ensuring accurate flow restriction and pressure drop characteristics essential for consistent slurry processing.

Working Principle

Operates on the principle of differential pressure measurement: as starch slurry flows through the precisely sized orifice, it creates a pressure drop proportional to flow rate. This pressure differential is measured to determine flow velocity and volume, enabling precise control of slurry delivery to downstream processes.

Materials

316L stainless steel (food-grade), with optional electropolished finish for reduced slurry adhesion. Alternative materials: 304 stainless steel for general applications, Hastelloy C-276 for corrosive starch additives.

Frequently Asked Questions

Why use 316L stainless steel for starch slurry orifice plates?

316L stainless steel provides excellent corrosion resistance against starch slurry components, meets food-grade requirements, and maintains dimensional stability under thermal cycling common in starch processing.

How does orifice plate accuracy affect starch slurry processing?

Precise orifice dimensions ensure consistent differential pressure readings, which directly impacts slurry flow rate control. Inaccurate flow measurement can lead to improper starch concentration, affecting product quality and process efficiency.

What maintenance is required for orifice plate bodies in starch applications?

Regular inspection for slurry buildup, cleaning of orifice edges to maintain sharpness, and verification of dimensional tolerances. Electropolished surfaces reduce cleaning frequency by minimizing starch adhesion.
