Purpose of ASME Design Codes:
Before the start of design work on any new project we need to know what the design code is,since the piping system would be designed according to the guidelines & the requirement of the applicable code.
Generally the information on the applicable code would be given by the owner or the Process Licensor in the Basic Engineering Package(BEP) or Piping design basis. The design contractors has to get this information before they start their work & if missing they need get it confirmed it with the owner.The design contractor shall ensure they are following the latest edition of the code.
As per ASME code:
“It is the owner’s responsibility to select the Code Section that most nearly applies to a proposedpiping installation. Factors to be considered by the owner include limitations of the Code Section;jurisdictional requirements; and the applicability of other codes and standards. All applicablerequirements of the selected Code Section shall be met. For some installations, more than oneCode Section may apply to different parts of the installation. The owner is also responsible forimposing requirements supplementary to those of the Code if necessary to assure safe pipingfor the proposed installation.
The design contractors shall also ensure that we are using the latest & the correct edition of the code.”
List of ASME codes:
Below are the ASME codes used for the design of the piping system in the oil & gas industry:
– Power Piping: piping typically found in electric power generating stations, in industrialand institutional plants, geothermal heating systems, and central and districtheating and cooling systems
– Process Piping: piping typically found in petroleum refineries; chemical,pharmaceutical,textile, paper, semiconductor, and cryogenic plants; and related processing plantsand terminals
– Pipeline Transportation Systems for Liquids and Slurries: piping transporting productsthat are predominately liquid between plants and terminals and within terminals,pumping, regulating, and metering stations
– Refrigeration Piping: piping for refrigerants and secondary coolants
– Gas Transmission and Distribution Piping Systems: piping transporting products thatare predominately gas between sources and terminals, includingcompressor, regulating,and metering stations; gas gathering pipelines
– Building Services Piping: piping typically found in industrial, institutional, commercial,and public buildings, and in multi-unit residences, which does not require therange of sizes, pressures, and temperatures covered in B31.1
– Slurry Transportation Piping Systems: piping transporting aqueous slurries betweenfacilities, plants, and terminals, and within terminals and pumping and regulatingstations.
– Hydrogen Piping and Pipelines: piping in gaseous and liquid hydrogen service andpipelines in gaseous hydrogen service.
As per ASME code:
Certain piping within a facility may be subject to other codes and standards, including but not limited to
– ANSI Z223.1 National Fuel Gas Code: piping for fuel gas from the point of delivery to theconnection of each fuel utilization device
– NFPA Fire Protection Standards: fire protection systems using water, carbon dioxide,halon,foam, dry chemicals, and wet chemicals
– NFPA 99 Health Care Facilities: medical and laboratory gas systems
– Building and plumbing codes, as applicable, for potable hot and cold water, and for sewerand drain systems
