QED Environmental Systems, Inc. has upgraded its ORP215M-R precision orifice plate wellhead, offering plate exchanges which give more accurate flow measurement with precise adjustment of gas flow, especially at very low rates (below 10 standard ft3/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 by and helps prevent loss of the orifice plates. With plates readily at hand, gas fields can be kept properly tuned for the best performance.
Changing to the correct orifice plate takes only seconds, with no need to shut down the control valve or retune the well. The precision fine tune control valve provides exact gas flow control, achieving near linear flow adjustment across its entire range.
The QED ORP215M-R wellhead features heavy-duty engineered plastic construction and moulded, glass-filled polypropylene which boosts its resistance to UV, weather and harsh field conditions. By tuning the wellhead to maintain differential pressure (DP) of 0.5–5-in of water column vacuum, wellheads operate at the optimum rate.
