Duplex stainless steel 316L concentric eccentric orifice plate
1. Definition of Duplex stainless steel 316L concentric eccentric orifice plate
An orifice plate is a thin plate with a hole in it, which is usually placed in a pipe. Orifice plates are one of the most popular devices for the measurement and control of fluid flow. The shape and manufacturing tolerances of plates used in measurement applications are defined in the international standardization publications of ISO, AGA, ASME and others. From the formulas and data within these publications, the relationships and values of flow, differential pressure, and plate bore are determined.
RTJ type orifice plates may be machined in one piece, or alternatively from two pieces, with an orifice plate screwed onto a carrier ring/gasket.
Standard material grades for orifice plates include 316 Stainless Steel, 304 Stainless Steel, 310 Stainless Steel, Hastelloy® C276, Hastelloy® B3, Duplex Stainless Steel, Super Duplex Stainless Steel, Monel® 400, Carbon Steel, Titanium, Incoloy® 800, Incoloy® 825, Inconel® 600 and Inconel® 625.
| Element | Type 316 (%) | Type 316L (%) |
| Carbon | 0.08 max. | 0.03 max. |
| Manganese | 2.00 max. | 2.00 max. |
| Phosphorus | 0.045 max. | 0.045 max. |
| Sulfur | 0.03 max. | 0.03 max. |
| Silicon | 0.75 max. | 0.75 max. |
| Chromium | 16.00-18.00 | 16.00-18.00 |
| Nickel | 10.00-14.00 | 10.00-14.00 |
| Molybdenum | 2.00-3.00 | 2.00-3.00 |
| Nitrogen | 0.10 max. | 0.10 max. |
| Iron | Balance | Balance |
Common carrier ring/gasket materials include Stainless Steel and soft iron. To ensure correct sealing when installed between flanges, the hardness of the carrier ring/gasket material is limited to a maximum value, typically 120 for soft iron rings and 160 for Stainless Steel Rings.
