Diaphragm Seals Type SMJ and SNJ Series Diaphragm Seal Elements for Jacketed Pipelines DESCRIPTION Mansfield & Green Type SMJ and SNJ Series diaphragm seals are flow thru type seals designed for pressure measurement applications involving jacketed pipelines where Type SMJ heated process fluids are used. The SNJ seals have slip-on flanges for ease of installation and alignment. Socket weld jacket connections are included for field installation. The SMJ model is similar to the SNJ seals except these seals do not include flanges. The SMJ seal is butt welded directly into the customer’s jacketed pipeline. Type SMJ and SNJ seals are continuous duty and feature a welded diaphragm seal design with the diaphragm welded directly onto the instrument housing. The interior of the diaphragm top is contoured to fit the movement of the diaphragm at maximum allowable deflection. This minimizes distortion. A filling screw is provided standard. Type SMJ and SNJ jacketed seals are available with 316 ELC stainless steel diaphragms and exposed parts. Other materials are available. Jacket pipe, connections, and flanges are Schedule 40 carbon steel. Standard seals are furnished with ANSI Class 150 or 300 flanges. The SNJ operating pressure is flange dependent. The SMJ seal pressure rating conforms to the Schedule 40 process pipe rating of 1500 psig at 100°F (103 bar at 38°C). • Ideal for jacketed pipeline applications - Welded diaphragm - Diaphragm welded directly to instrument housing • Continuous duty • SNJ features slip on flanges for easy installation - Socket weld connections included on jacket • SMJ butt welded directly to pipeline • Materials available for corrosive applications • Pressure ranges to 1500 psig (103 bar) ALL ORDERS CAN BE SENT TO: On-line fax: 215-323-9450 or e-mail to usg.sales@ametek.com © 2008, by AMETEK, Inc.
