400 GENERAL STATEMENTS
(a) This Liquid Transportation Systems Code is oneof several sections of the ASME Code for Pressure Piping, B31. This Section is published as a separate document for convenience. This Code applies tohydrocarbons,liquid petroleum gas, anhydrous ammonia, alcohols, and carbon dioxide Throughout this Codethese systems will be referred to as Liquid PipelineSystems.
(b) The requirements of this Code are adequate forsafety under conditions normally encountered in theoperation of liquid pipeline systems. Requirements forall abnormal or unusual conditions are not specificallyprovided for, nor are all details of engineering and construction prescribed. All work performed within theScope of this Code shall comply with the safety standards expressed or implied.
(c) The primary purpose of this Code is to establishrequirements for safe design, construction, inspectiontesting, operation, and maintenance of liquid pipelinesystems for protection of the general public andoperating company personnel as well as for reasonableprotection of the piping system against vandalism andaccidental damage by others and reasonable protectionof the environment.
(d) This Code is concerned with employee safety tothe extent that it is affected by basic design, qualityof materials and workmanship,and requirements forconstruction,inspection, testing, operation, and maintenance of liquid pipeline systems. Existing industrialsafety regulations pertaining to work areas, safe workpractices, and safety devices are not intended to be supplanted by this Code.
(e) The designer is cautioned that the Code is not adesign handbook. The Code does not do away with theneed for the engineer or competent engineering judgment. The specific design requirements of the Code usually revolve around a simplified engineering approachto a subject. It is intended that a designer capable ofapplying more complete and rigorous analysis to specialor unusual problems shall have latitude in the development of such desiens and the evaluation of complex orcombined stresses,In such cases the designer is responsible for demonstrating the validity of his approach.
(f) This Code shall not be retroactive or construedas applying to piping systems installed before date ofissuance shown on document title page insofar as design, materials, construction, assembly, inspectionand testing are concerned. It is intended, however, thatthe provisions of this Code shall be applicable within 6months after date of issuance to the relocation, replacement, and uprating or otherwise changing existing piping systems; and to the operation, maintenance,andcorrosion control of new or existing piping systems.After Code revisions are approved by ASME and ANSIthey may be used by agreement between contractingparties beginning with the date of issuance. Revisionsbecome mandatory or minimum requirements for newinstallations 6 months after date of issuance except forpiping installations or components contracted for orunder construction prior to the end of the 6 monthperiod.
(g) The users of this Code are advised that in someareas legislation may establish governmental jurisdic-tion over the subject matter covered by this Code andare cautioned against making use of revisions that areless restrictive than former requirements without havingassurance that they have been accepted by the properauthorities in the jurisdiction where the piping is tobe installed.The Department of Transportation, UnitedStates of America, rules governing the transportationby pipeline in interstate and foreign commerce of petroeum,petroleum products, and liquids such as anhy-drous ammonia or carbon dioxide are prescribed underPart 195 – Transportation of Hazardous Liquids byPipeline，Title 49 Transportation, Code of FederalRegulations.
400.1 Scope
400.1.1This Code prescribes requirements for thedesign, materials,construction,assembly, inspectionand testing of piping transporting liquids such as crudeoil, condensatenatural gasoline, natural gas liquidsliquefied petroleum gas, carbon dioxide, liquid alcoholliquid anhydrous ammonia, and liquid petroleum products between producers’ lease facilities, tank farms, natural gas processing plants, refineries, stations, ammoniaplants, terminals (marine. rail. and truck), and otherdelivery and receiving points.(See Figs. 400.1.1 and400.1.2.)
