Orifice Plate Design Standards

The CRSI Design Handbook has been the reference book for cast-in-place reinforced concrete design since 1952. The 10th edition provides the necessary information needed for common reinforced concrete structural members such as columns, beams, footings, pile caps, retaining walls, and...

This standard is intended to cover only orifice plates designed for bolting between flanges, with flat or raised face, whose bolting dimensions are in accordance with one of the following ASA standards: B16b2 B16.1 B16b B16.5-1957 PURPOSE The purpose of this Standard is to...

This Standard covers pressure-temperature ratings, materials, dimensions, tolerances, testing, and making of flanges (similar to those covered in ASME B16.5) that have orifice pressure differential connections. Coverage is limited to the following: (a) welding neck flanges Classes 300, 400,...

This Practice provides fabrication details and describes the minimum requirements for fabricating concentric or eccentric square edge orifice plates and the orifice meter run.

SCOPE AND FIELD OF APPLICATION This Standard specifies the geometry and method of use (installation and flowing conditions) for orifice meters of 6 mm to 40 mm (¼ in. to 1½ in.) line size when they are inserted in a conduit running full. It also gives necessary information for calculating...

This Practice provides installation details and describes the minimum requirements for installing orifice plates in gas, liquid, steam, or condensing vapors service.

5.1 This test method provides design information for construction of an orifice weir. It also describes setup, operation, inspection, calculation of discharge, and reporting. The accuracy of a circular weir decreases at low flows. The use of a circular orifice weir requires a...

FOREWORD This report analyzes four flange tap equations and three corner tap equations for the discharge coefficient for orifice plates. All of the equations analyzed are functions of Beta Ratios, Reynolds Number, and Line Size, and all data points were evaluated against each of the...

INTRODUCTION Description As its name implies, an orifice meter utilizes an orifice for its basic component in the measurement of natural gas. The placing of an orifice in a pipe in which there is gas flow creates a pressure difference across the orifice. This pressure...

This specification covers the acceptable design details for the plenum chamber used in specified air performance measurement tests for vacuum cleaners. Plenum chambers conforming to this specification shall be fabricated in accordance with the dimensions, tolerances, and notes indicated for...
