FUNCTIONING AND STRUCTURE
1. Type “K” Standard 2000 Edition Seal Assembly
This is the standard seal assembly supplied with all orifice fittings from sizes 2” through 8”. This unit is used with a 0.562” seal gap for fitting sizes 2” thru 6” and with a 0.688” seal gap for 8” fittings. The single downstream seal function offers superior sealing capability while reducing seal damage during insertion. Plate Seal bypass tested down to 1” water column. It is comprised of an elastomer seal and one stainless steel retainer ring. Exacting and repeatable concentricity is maintained with the metal-to-metal contact throughout the entire circumference of the orifice plate to the plate carrier mechanism.
2. Dual Ring Orifice Plate Seal Assembly
Canalta Dual Ring Orifice Place Seal Assembly offers you (The Customer) an alternative sealing device for those specific or unorthodox situations. This assembly is primarily used to upgrade the .688” seal gap (1985 Edition) orifice fitting bodies to comply with the latest editions of AGA-3 and ISO-5167 but is also available for 0.562” gap fittings (2000 Edition) per customer request. The seal assembly simply mounts into place in the existing plate carrier. It is comprised of a stainless steel plate holder, retainer ring and standard sized O-Ring seals which are available in a variety of compositions. A positive seal is established with the orifice plate and the seal surfaces of the orifice fitting body utilizing the “inner and outer O-Ring” design. Plate seal bypass tested down to 1” water column. When ordering the Dual Ring Orifice Plate Seal Assembly please specify 0.688” seal gap (1985 Edition) or 0.562” plate seal gap (1991 / 2000 Edition).
3. Teflon Snap Seal
The Teflon Snap Seal Provides Positive Plate Sealing in the harshest of process environments. The two piece design snaps over the orifice plate without the use of metal clips or retainers. A specially designed recess absorbs the insertion pressures minimizing permanent compression and distortion. The raised section adjacent to the recess creates a positive seal against the orifice plate preventing bypass leakage. These two unique design features enhance seal performance while extending the life expectancy of the seal assembly.
Soft Seat Details
This unique soft seat design is available at no extra charge. It enables a maintenance free bubble tight seal between upper and lower chambers. Standard size O-Ring seals are incorporated and available in a wide variety of compositions.
Installation Instructions
Orifice Fitting Installation Procedure The Orifice Fitting is normally installed in conjunction with upstream and downstream meter run sections. To meet the recommendations of both A.G.A. Report 3 and ISO 5167, this is essential. To obtain the best measurement results, follow the recommended piping configurations and installation requirements of either of these two standards as well as the below recommendations. The meter run is normally constructed and inspected by the manufacturer of the orifice fitting but there are many reputable meter run fabrication facilities located worldwide.
- Attention to clearances is essential. See the attached dimensional drawings for details. Insure there is operating clearance on the sides of the fitting to rotate the inner valve and orifice plate carrier shafts. Insure there is clearance above the top of the fitting for removal of the plate carrier.
- The unit can be installed either in a vertical or horizontal position. When mounting horizontally, the top housing should be located in the upper position for ease of operation as well as to avoid liquid and debris from accumulating in the upper chamber.
- When used to measure wet gas, it is recommended to mount the orifice fitting vertically so as not to form a dam against the orifice plate.
- Instrument tap lines should be installed sloping upward to the differential pressure measurement instrument. Where this cannot be accomplished, use seal pots to chemically seal the sensing lines in order to eliminate hydrostatic head errors.
- Insure that the flow arrow corresponds with the direction of flow in the line.
- After the orifice fitting has been piped in, install the bleeder valve, grease gun and indicator plate on the valve-operating shaft.
- With the two drive screws provided, install the valve position pointer. Insure that the position on the valve indicator plate corresponds with the position of the inner valve.
- It is recommended that the bleeder valve vent be piped away to a safe venting area.
- To avoid damage to the orifice plate, insure the orifice plate and plate carrier are removed from the fitting during pressure testing of the system.
- Before reinserting the orifice plate and plate carrier, insure that no debris has accumulated in the lower cavity of the fitting. If so, remove the lower drain plugs and rod-clean the lower section.
- The orifice fittings equipped with the grease style inner valves were lubricated at the factory prior to shipment. If the unit has been sitting out of service for more than six months, it is recommended that the unit be lubricated prior to being put into service. Refer to the “Lubrication Procedure”.
- To avoid over range damage to the differential measurement instruments and orifice plate during initial pressurization, insure the orifice plate is rolled up out of the flow stream and that the instrument manifold equalization valves are open. 13. Always insure that operation staff are properly trained and are competent to operate this and all other pressurized equipment.
