• Orifice size is permanently stamped on body for ease of identification. • Can eliminate or minimize costly flow control valves. • A line of orifice adapters that will replace a traditional port adapter is also available upon request. • Available in steel in sizes 1/4”, 3/8” and ½” with working pressures up to 12,000 psi

An orifice only works well when supplied with a fully developed flow profile. This is achieved by a long upstream length (20 to 40 pipe diameters, depending on Reynolds number) or the use of a flow conditioner. Orifice plates are small and inexpensive but do not recover the pressure drop as well as a venturi, nozzle, or

The diameter of an orifice is much smaller than the inner diameter of the connected piping. For example, the orifice diameters available for the J3X Free Float® steam trap are only approx. 2-3 mm [⅛ inch] or less. Its purpose is to limit the injection flow rate to the seal and to control pressure in the seal chamber. A minimum bore diameter or 3 mm (1/8") is normally specified (to minimize potential of blockage) and the orifice can either be installed between flanges or in an orifice nipple. In a small orifice, the size of the orifice is so small compared with the head over it, the velocity at the level of the centre of the orifice may be taken as the mean velocity through the orifice.

When this occurs, the next larger orifice size is chosen resulting in the valve being oversized with just an API orifice; The certified ASME discharge coefficient is derated by a factor of 0.9 resulting in another potential source of over design; Spray pressure and nozzle orifice size influences the droplet size and the spray rate.

Thicknesses E and e The thickness e of the orifice shall be between 0,005D and 0,02D. The difference between the values of e measured at any point on the orifice shall not be greater than 0,001D. The thickness E of the plate shall be between e and 0,05D. However, when 50 mm ≤ D ≤64 mm, a thickness E up to 3,2 mm is acceptable

Utilizing the concept of an equivalent orifice, as the bearings in the system wear, the orifice diameter becomes larger, therefore the flow required to the critical equipment will be greater.

The manufacturer of the orifice flange set drills the taps so that the centrelines are 1 in. (25 mm) from the orifice plate surface. Flange taps are not recommended below 2 in. (50 mm) pipe size and cannot be used below 1.5 in. (37.5 mm) pipe size, since the vena contracta may be closer than 1 in. (25 mm) from the orifice plate.

A. According to size: Small orifice Large orifice B. According to shape: Circular orifice Rectangular orifice Triangular orifice C. According to shape of edge: Sharp-edged Bell-mouthed D. 2012-08-08 In a small orifice, the size of the orifice is so small compared with the head over it, the velocity at the level of the centre of the orifice may be taken as the mean velocity through the orifice. In a large orifice however, this is not correct. An orifice may be circular, rectangular or square though often, circular orifices are adopted. This easy-to-use calculator will help you calculate the orifice size of your valve By manufacturing an orifice plate in such a way that the hole exhibits “venturi-like” properties (i.e. a dull edge where the fast-moving fluid stream has more contact with the plate), these two effects tend to cancel each other, resulting in an orifice plate that maintains consistent accuracy at lower flow rates and/or higher viscosities than the simple square-edged orifice. 2011-09-19 and thus, the final equation for the non-choked (i.e., sub-sonic) flow of ideal gases through an orifice for values of β less than 0.25: Using the ideal gas law and the compressibility factor (which corrects for non-ideal gases), a practical equation is obtained for the non-choked flow of real gases through an orifice for values of β less than 0.25: [ 3 ] [ 4 ] [ 5 ] 2019-04-02 The high pressure outlet (H) is located 1 inch (25.4 mm) before the plate and the low pressure (L) 1 inch (25.4 mm) after the plate.
