Detailed Introduction

Description

Restriction orifice plates are widely used for many applications within the industry. Although the design is very similar to an orifice plate, the function is different. Restriction plates are used to suit a number of different purposes including.

● Reduction in line pressure

● Control flow rates by restricting flow, regardless of downstream conditions

Design considerations	● Prevent critical flow ● Removal of cavitation ● Reduce noise levels We offer a number of different restriction designs to suit the needs of your application
Configuration	● Restriction plates (Standard applications) ● Multi-hole restriction plates (Used to reduce noise) ● Multi-stage restriction units (Flanged / Butt-weld) ● Conical shaped restriction orifice (Eliminated damage caused by cavitation)
Benefits	● Proven design technology ● Products designed in accordance with R.W.Miller - Flow engineering handbook ● Plate thickness calculations designed in accordance with ASME B31.3 ● Designs available to accommodate site restrictions and noise limitations ● Prevent critical flow or cavitation issues
Applications	● Hydrocarbon gas and liquids ● Controlled pressure reduction ● Blow-down service ● Pressure vessels ● Noise reduction
Key parameters	● Proven technology ● Prevent critical flow or cavitation issues ● Reduce site restrictions and noise levels
Standards	● R.W. Miller ● ASME B31.3 ● ISA standard design
