Upgrades to ORP215M-R precision orifice plate wellhead

Q.E.D. Environmental Systems, Inc., a leading manufacturer of innovative environmental products and subsidiary of Graco Inc., announces upgrades to its industry-leading ORP215M-R precision orifice plate wellhead.

The QED ORP215M-R wellhead combines easy plate exchanges for more accurate flow measurement with precise adjustment of gas flow, especially at very low rates (below 10 standard cubic feet per minute). The new design includes a complete kit of six orifice plates securely attached to the wellhead for quick access. A permanent stainless-steel S-type orifice plate retainer keeps the plates close at hand and helps prevent loss of the orifice plates. With plates readily at hand, it is easier to keep gas fields properly tuned for the best performance.

Changing to the correct orifice plate takes only seconds, with no time wasted shutting down the control valve or retuning the well. The precision fine tune control valve provides exact gas flow control. Unlike traditional valves, this unique design achieves near linear flow adjustment across its entire range. The serviceable control valve includes a stainless-steel rod for long service life.

The QED ORP215M-R wellhead features heavy-duty engineered plastic construction – tougher and stronger than PVC. Molded, glass-filled polypropylene boosts strength and resistance to UV, weather and harsh field conditions, significantly increasing wellhead durability. A tapered connection makes hose fitting easy, while simpler service saves valuable field time and helps reduce maintenance and labour costs.

QED’s Easy Port fittings are engineered specifically for landfill gas wellheads. Made with fiber-reinforced engineered plastic, they have a screw-on bird-proof cap that seals tightly. The sample ports feature heavy walls to reduce heat loss and freezing, and are UV protected for much longer field life. The cap seals tightly but can be easily removed with a simple twist. It is tethered to the fitting so it cannot be dropped or lost.

The upgraded ORP215M-R wellhead allows operators to have the exact orifice plate for efficient tuning right at hand. By tuning the ORP wellhead to maintain differential pressure (DP) of 0.5 to 5-inches of water column vacuum, wellheads operate at the optimum rate. When used with the QED GEM5000 portable gas analyzer, technicians can monitor and tune wellheads to match changes in field flow, keeping the optimum DP.
