QED Environmental Systems, Inc. has upgraded its ORP215M-R precision orifice plate wellhead, offering plate exchanges which give more correct move measurement with precise adjustment of gasoline circulate, particularly at very low charges (below 10 standard ft3/minute).
The new design includes a full equipment of six orifice plates securely attached to the wellhead for fast access. A everlasting stainless-steel S-type orifice plate retainer keeps the plates shut by and helps forestall lack of the orifice plates. With plates readily at hand, gasoline fields may be saved properly tuned for one of the best performance.
Changing to the correct orifice plate takes only seconds, without having to shut down the management valve or retune the well. เกจวัดแรงดันลม supplies actual gasoline move management, achieving near linear circulate adjustment across its whole range.
The QED ORP215M-R wellhead options heavy-duty engineered plastic building and moulded, glass-filled polypropylene which boosts its resistance to UV, climate and harsh field conditions. By tuning the wellhead to take care of differential pressure (DP) of 0.5–5-in of water column vacuum, wellheads function at the optimum price.
