About this file

This document is a comprehensive installation instruction manual for ROVANCO's Insul-800 High Temperature Conduit System, supplemented by complete design and shop drawings for high-pressure steam and pumped condensate piping systems. The manual provides detailed technical guidance for field installation, testing, and maintenance of pre-insulated underground piping systems designed for temperatures of 210°F and above.

The installation manual covers thirteen major sections addressing the complete system lifecycle: inspection and unloading procedures; welding of carrier pipe with hydrostatic testing at 1½ times operating pressure (not exceeding 250 psig); cold springing instructions using angle irons and threaded rods for expansion compensation; field alteration procedures requiring ROVANCO authorization; insulation of field joints using either sectional or poured-in-place foam methods; connector band welding and air testing at 15 psi; test can application for conduit verification; detailed insulation and sealing procedures with mixing charts for Mid-Temp Foam and Polyurethane Foam; concrete anchor installation specifications; backfill requirements with minimum 6-inch clean backfill above the conduit; inner conduit casing drying procedures using compressed air ventilation; manhole and building entry specifications; and annual maintenance protocols including drain plug inspection, air testing at 15 psig, leak repair procedures, and system shutdown protocols. The system specifications indicate 10-gauge steel inner conduit casing with mineral wool or high-temperature foam insulation, a nominal 2-inch high-temperature foam insulation layer, and a heavyweight polyethylene outer jacket. All carrier pipes must undergo hydrostatic and air testing prior to concrete anchor installation or system backfilling. The accompanying shop drawings provide isometric and detailed sectional views of complete piping layouts, pump configurations, valve arrangements, and connection details for high-pressure steam and condensate systems. Installation must follow provided drawings and comply with ANSI B31.1 standards, with technical support available through ROVANCO's customer service department in Joliet, Illinois.
