Provide thermometers (or temperature gauges) on all four legs of water-to-water heat
exchangers, and on both fluid legs of steam converters.
All fired or unfired pressure vessels whether a part of an equipment package or an
entire piece of equipment shall be specified to comply with the ASME Code. The
specifications shall require that the pressure vessel be so stamped in an easily
identifiable location and that the manufacturer’s data indicating ASME compliance be
submitted.
Comply with the Boiler and Pressure Vessel Rules and Regulations issued by DLI.
BSRV 4.3.3.4 EXPANSION JOINTS
Expansion joints on heating pipe shall be class 300 packed slip type or ball joints,
packable under pressure. Bellows type expansion joints shall not be used. Expansion
joints on HPS, pumped condensate and MTHW shall have welded joints rather than
flanges. Where appropriate slip expansion joints with an integral foot can be used in lieu
of an expansion joint and separate anchor. Acceptable manufacturers are Adsco,
Advanced Thermal Systems, and Yarway. Provide calcium silicate insulation on the main
body of the expansion joints and provide a removable flexible insulation blanket that
over laps the calcium silicate by 4” on each side. Install slip expansion joints so the pipe
expands into the joint in the direction of flow.
BSRV 4.3.3.5 INSULATION
Insulation in steam and MTHW tunnels shall be fiberglass rated for 800 degrees F with
an aluminum jacket or calcium silicate with waterproof 30 pound felt jacketing; applied
to fittings with waterproof adhesive and copper or stainless steel wires. Insulation on
high pressure steam, pumped condensate, and MTHW in mechanical rooms shall be
fiberglass rated for 800 degrees or calcium silicate with a glued canvas jacket. The
minimum insulation thickness on HPS and MTHW shall be 4” on pipe 6” and above and
3” on pipe 4” and smaller. Removable insulation blankets with double D-rings and
straps shall be provided on all steam, condensate and hot water valves and fittings that
cannot be properly fitted with fiberglass or calcium silicate insulation.
BSRV 4.3.3.6 MISC HEATING COMPONENTS
All duct reheat coils shall have access doors or panels to allow door inspection and
cleaning of coil inlet.
Adequate room shall be provided to remove hot water coils for cleaning and/or repair.
All fittings on secondary hot water systems shall be class 150 or better.
Paper/compressed fiber flange gaskets shall not be used.
