Pikotek® flow restriction orifice plates feature a one-piece orifice plate design for critical flow line and pipeline flow restriction and flow measurement applications. Their one-piece design eliminates the need for conventional orifice plates, plate holders and separate gaskets, substantially reducing residual flange/bolt stress in orifice flanges and improving overall sealing performance under even the most extreme operating conditions in all hydrocarbon production, injection and process applications.
One isolating and sealing orifice plate product comprised of a 316 stainless steel plate bonded to a G-10 fiber glass reinforced laminate. The orifice plate will be either .260” thick or .308" thick. The sealing surface will contain a precision tapered groove to accommodate the controlled compression of a PTFE spring energized seal. Sealing element placement shall accommodate either flat, raised or RTJ face flanges. The PTFE seal shall be spring and pressure energized. The G-10 retainer shall have a 800 volts/mil dielectric strength and a minimum 65,000 psi compressive strength.
