D/P Flow & Pressure Winterization

Winterization of Instruments with Vipak and Heaters. An O'Brien Vipak instrument enclosure is used to maintain freeze protection for a D/P and pressure transmitter in a flow loop. Freeze protection is maintained to -20 degrees F. The instrument enclosure also provides a power connection kit for electric tracer power. The instruments and manifolds were supplied by the customer and mounted in the enclosure complete with internal crossover tubing and electrical conduit for transmitter wiring installed by O'Brien. The impulse lines from the orifice taps were constructed with O'Brien Tracepak. The tubing and electric tracing in the impulse lines were bent with tube fitting ferrules set for connection to the instrument in the field. Heat shrink boots were also located and shrank to the tubing bundle by O'Brien prior to shipment. The enclosure was shipped with appropriate O'Brien Saddlepak instrument support modules for the specific installation requirements.

Advantages to this system approach are installation of instruments, tubing, and brackets by factory personnel trained and experienced with the components in a shop environment. Design and procurement of all necessary components by O'Brien Corporation allows the customer to issue a single purchase order. The enclosure arrives on site ready to install; the instruments and trace power kit are installed; crossover tubing is installed; tubing fittings are installed; and the impulse line connects by tightening two tube fittings on the tubes that are pre-bent to connection centers.
