Canalta Orifice Fitting Parts & Accessories
Precision Machined for Accuracy, Reliability and Performance
Canalta Flow Measurement is a privately held Canadian company that began operations in 1986 as an instrumentation and electrical contractor. Since 1991, the focus has been on the manufacture of industrial control and measurement equipment. The company now manufactures and services several product lines specifically targeting the oil and gas industries, and supplies product across North America, South America, Asia and the Middle East. Canalta has grown to include primary manufacturing and warehousing facilities in Red Deer, Alberta and Dallas, Texas, a direct sales office in Buenos Aires and an extensive global distribution network.
PARTS FOR ALL DUAL CHAMBER & 8"+ SINGLE CHAMBER ORIFICE FITTINGS
include a full complement of orifice fitting parts, allowing for a complete rebuild of the orifice fitting or replenishment of spare parts inventory. These kits are available with 4130 yellow zinc plated carbon steel internals for standard applications, or 316 stainless steel internals for extreme corrosive applications. All repair kits include high grade HNBR internal seals and are packaged in a sturdy resin case for easy storage or transport. Repair kits for Daniel* Junior and Senior Orifice Fittings are equally comprehensive, substituting Garlock gaskets for the standard Canalta body, valve seat and seal bar O-ring seals. These parts can also be supplied on an individual basis. Please contact us for full details on our servicing of Daniel product lines.
ORIFICE PLATES & PLATE SEALS
The Type “K” Standard 2000 Edition Seal Assembly is the standard seal supplied with all Canalta Orifice Fitting model sizes 2″ through 8″. The assembly is comprised of a HNBR elastomer seal and stainless steel retaining ring. The single downstream seal function offers superior sealing capability while reducing seal damage during insertion. This design cuts in half the seal’s compressible material, resulting in less seal swell common in most applications. The durability of the stainless steel retaining ring leads to replacement costs of approximately 1/3 that of other plate seals. Exacting and repeatable concentricity is maintained with the metal to metal contact throughout the entire 360° circumference of the orifice plate to the plate carrier mechanism. This unit is used with a .562″ seal gap for fittings sized 2″ through 6″, and with a .688″ seal gap for 8″ fittings, meeting the 1992 and 2000 editions of AGA-3. Plate seal bypass tested down to 1″ water column.
FLOW CONDITIONING ACCESSORIES
FLOW CONDITIONERS maximize orifice meter accuracy while significantly reducing upstream pipe length requirements. This design fully develops the fluid flow profile (known as an “isolating” flow conditioner) without creating a significant pressure drop. Accurate flow metering is possible in a host of line configurations, including multiple elbows and tee intersections. Installation, maintenance and initial capital cost are easy and economical, and the resilient one-piece design ensures a long service life. Standard 316 stainless steel makes these flow conditioners suitable for all applications, including extremely corrosive environments. A variety of configurations, from Zanker to #50-style flow conditioners, are available. Pin-style flow conditioners are line mounted with a 3/4″ set pin in the wall of the upstream pipe. Available for schedule 40 or 80 pipe sizes 2″ through 30″.
