SHOP DRAWINGS HIGH PRESSURE STEAM PUMPED ROVANCO PIPING SYSTEM.pdf

This document comprises shop drawings and field installation instructions for the ROVANCO Insul-800 High Temperature Conduit System, a pre-insulated piping system designed for underground high-temperature applications (210°F and above). The specification section 33 63 00 includes detailed engineering drawings showing the complete system design with components including inner conduct casing (10-gauge steel), carrier pipe (copper, stainless steel, or carbon steel), mineral wool or high-temperature foam insulation, and outer polyethylene jacket. The system is designed to be drainable, dryable, and air-testable with all piping supplied in pre-fabricated, cut-to-length pieces with elbows, tees, anchors, and end seals.

The field installation instructions (INS-HTC) provide comprehensive guidance for system installation, including procedures for inspection and unloading, proper storage at controlled temperatures (60°-70°F), welding of carrier pipe with mandatory hydrostatic testing at 1.5 times job working pressure (not exceeding 250 psi), cold springing instructions with standard and "Bridge Method" approaches, field joint insulation using either sectional insulation or poured-in-place foam, connector band welding and air testing at 15 psi, test can application procedures, and concrete anchor pouring with minimum 10-inch clearance. The instructions also address inner conduit casing insulation and sealing, backfilling requirements with minimum 6-inch clean backfill cover, annual maintenance including drain plug inspection and yearly air testing at 15 psi, repair procedures for leaks, and system shutdown protocols. Standard specifications detail material requirements including minimum insulation density of 2.0 psi and K-factor of 0.130 at 75°F mean temperature, with approved vendor certification from ROVANCO (Joliet, Illinois) at (815) 741-6700.
