Steam and Condensate Systems

Abstract

NOTE: This guide specification is not intended as a final construction document. The Engineer-in-Responsible-Charge for each project must review and adapt this guide specification as necessary to accommodate the unique conditions of a particular project. The Engineer-in-Responsible-Charge shall provide the ASME B31.1 flexibility analysis and stress calculations and shall provide sufficiently detailed drawings to permit the contractor to build the piping system in compliance with ASME B31.1 The detailed drawings will show, at a minimum, the piping layout with all offsets, expansion loops and bends, expansion joints, supports, guides and anchors. PART 1 GENERAL 1.1 APPLICABILITY A. This specification applies to all steam and condensate utility system piping and equipment underground, in tunnels, concrete trench boxes, pre-insulated conduit systems, manholes and in building mechanical rooms. B. The steam utility system extends from the Central Energy Facility (CEF) up to and including the pressure reducing station and main safety relief valve in each building, including the steam consumption meter. C. The condensate utility system includes the main condensate return pump in each building and all piping and equipment downstream from the main condensate return pump back to the CEF.
