Orifice     
Tapping of differential pressure is done by this vener contractor tap Orifice. Since Orifice plate can be installed directly to flange of pipe, flow measurement by this Orifice plate can be performed more economically suited for large diameter pipes, As for large diameter pipes of 500mm or greater, these Orifice plates are used to measure the average value of pressure by making some differential pressure tapping holes around the pipe and connecting thereto a loop form pressure equalizing pipe.

 
Orifice Flange Plates

WOOIN TECH Paddle -Type Orifice Plates are used with Orifice Flange Unions. All outer diameters of the plates are machined, providing a uniformly circular disc. This results in a high degree of concentricity of the Orifice bore and the plate outer diameter. Next, handles are carefully welded on. the plates are then sanded in special machines to a prescribed finish. Bank plates and plates with popular bore size are stocked continuously. Each plate is stamped on its handle with line size, flange rating, Orifice bore and plate material, WOOIN TECH maintains a stock in Type 304 and 316 Stainless Steel in standard thickness. Other size and materials are available on request.

Diameters of holes in paddle Plate Handles are as flows:

Special Orifice Plate Bores

The bore and bevel is the standard of limiting the plate edge thickness. The bevel is machined on a 45°angle to the desired edge thickness. Unless otherwise specified, plates will be bevelled to 1/50 of the line I.D. or 1/8 of the Orifice bore, minimum governing.
ORIFICE PLATE

Eccentrically bored plates with the Orifice offcenter, or eccentric, as opposed to concentric. The bore of the eccentric Orifice normally in a circle with is 98% of the pipe diameter, so that solids or slurries may pass through, Eccentric Orifice plates are used in many industries including heavy and light chemicals, steel, paper, atomic and petrochemicals
ORIFICE PLATE

Segmentally bore Orifice plates are provided for measurements where solides are entrained in a gas or liquid flow stream. The circular portion of the bore is inscribed within a circle which is normally 98% of the pipe diameter.

The segmental opening may be placed either at the top or bottom of the pipe. Industries using these bores include sewage treatment, steel, chemical, water conditioning, paper, and petrochemical.

How WOOIN TECH Orifice Flanges Provide Better Measurement

 

Orifice flanges one of the most economical means of measuring flow, and WOOIN TECH Orifice Flanges are specially manufactured to be the most accurate. Automatic machine tools enable WOOIN TECH to meet the most stringent tolerances and recommendations for flanges, with careful attention given to tap location, bore smoothness, bolt and flange facings. WOOIN TECH Orifice Flanges are made of forged steel, A.S.T.M A-105. Other materials are available on special order and extended delivery.

1) FLANGE TAP

Both upstream and downstream are located at a distance of 25mm fron the Orifice plate.
This method is applicable to smaller pipes.

   

2) CONER TAP

Tapping for differential pressure is made at immediately up stream and downstream positions of the orifice. This system is used primarily for small pipes.(Smaller 2")

   

3) PIPE TAP

The differential pressure is small.
This Tapping system is not very popular.

 

 

4) VENA TAP

The tap for the upstream side is located at a distance of approximtely the pipe diameter and that for the down streem is located in a position of the lowest of pressure position.
