Orifice Plate Gaskets

Orifice plates, which is a thin metal plate with a hole bored in the center, are the simplest and the most commonly used type of components used for the measurement and control of fluid flow. Available in a wide range of sizes, they are inserted into the pipe carrying the flowing fluid for measuring flow rate, reducing pressure or restricting flow. Assuring good accuracy in many applications, these primary flow elements guarantee easy installation, effective and reliable service over many years. At SSP Manufacturing, we own decades of experience in designing, sizing, and manufacturing orifice equipment to the exact requirements of the customers. Being a leading manufacturer of orifice plates in the USA, we ensure producing these plates to the stringent guidelines and tolerance level.

Types of Orifice Plates Offered at SSP Manufacturing

Widely established as a cost-effective and competitive solution for flow rate measurement, orifice plates are offered at SSP Seals in the following types.

  • Square Edged Concentric Orifice Plates: Featuring simple structures, high accuracy, and ease of installation and replacement, these types of orifice plates are largely chosen for general applications with clean liquids and gases.
  • Eccentric Orifice Plates: Ideal for flow measurement of contaminated fluids with suspended solids or entrained gas, eccentric orifice plates are suitable for both horizontal and vertical piping. They are widely chosen amongst the customers in the chemicals, steel, paper, nuclear and petrochemicals industries.
  • Segmental Orifice Plates: They are chosen when there is entrained water or air or suspension in the fluids. These segmentally bored orifice plates are the most suitable option for sewage treatment, steel, chemical, water conditioning, paper and petrochemical industries.
  • Quadrant Edge Orifice Plates: Designed with rounded- or conical-entrance holes, quadrant edge orifice plates are used for the flow measurement of viscous fluids such as heavy crudes, syrups, and slurries with Reynolds.
