Interior Gas Distribution Technology for Tall Buildings. Phase 2. Case Study No.1. Evaluation of As-Installed versus Enhanced Gas Distribution System Valley Lo Apartments. Topical Report, August 1994

摘要

As Part of the research focusing on gas distribution issues within tall buildingsand addressing the technical and economic barriers to increasing the use of natural gas, this case study of an apartment building system analyzes a prototypical distribution concept representative of gas applications for most tall buildings. The concept includes a horizontal header, vertical riser, submeter stations, and horizontal piping network. Among other significant results of the study, it has shown that increasing the operating pressure of the distribution system, thus allowing the use of small diameter copper and corrugated stainless steel tubing, provides both a substantial increase in total gas delivery capacity and the ability to add future load. Appendixes include a description of the corrugated stainless steel tubing system and estimated costs of material and labor for the as-installed and enhanced piping systems.
