Exterior Distribution of Utility Steam, High Temperature Water (HTW), Chilled Water (CHW), Fuel Gas, and Compressed Air

摘要

Basic design guidance developed from extensive reevaluation of facilities is presented for use by experienced architects and engineers. Criteria are given for the design of an exterior distribution piping system for supplying utility steam, high temperature water, chilled water, cooling or condensing water, fuel gas, and compressed air to various buildings and facilities and for returning condensate and water to the central plant. Data required for the design include information on loads and fluid conditions, fluid characteristics, and distribution site locations. Factors governing tests for field permeability, soil resistivity, soil stability, and water conditions are given as is information on distribution pipe sizing, valves and supports, distribution methods, and piping specifications and codes. Contents also cover owning, operating and maintenance costs of permanent or temporary sites. (Author)
