1-100 INTRODUCTION Part 1 of this Standard defines the requirements that are applicable to all reinforced thermoset plastic corro- sion resistant vessels fabricated to this Standard and shall be used in conjunction with the specific require- ments in other Parts and Mandatory Appendices of this Standard. 1-110 Scope (a) This Standard applies to stationary vessels used for the storage, accumulation, or processing of corrosive or other substances at pressures not exceeding 15 psig external and/or 15 psig internal above any hydro- static head. (b) In relation to the geometry of vessels, the scope of this Standard shall include the following: (1) where external piping is to be connected to the vessel (-a) the first threaded joint for screwed connections (-b) the face of the first flange for bolted connections (-c) the vessel side sealing surface for proprietary connections or fittings (2) the vessel attachment joint when an attachment is made to either the external or internal surface of the vessel (3) covers for vessel openings, suchas manhole and handhole covers (4) the vessel side sealing surface for proprietary fittings, such as gages and instruments, for which rules are not provided by this Standard 1-120 Exclusions The following types of reinforced thermoset plastic equipment are excluded from the rules of this Standard: (a) vessels with MAWP or MAEWP in excess of 15 psig (b) hoods, ducts, and stacks (c) fans and blowers 1 (d) vessel internals such as entrainment separators, chevron blades, packing support plates, and liquid dis- tribution plates (e) pumps (f) pipe or piping (see ASME B31.3) (g) fully buried underground closed vessels 1-130 Application Limitations Vessels specified, designed, fabricated, and certified by the Fabricator as conforming to this Standard shall be limited to the following pressure and temperature limits: (a) Maximum Internal Pressure 1 (1) With Proof Test of As-Constructed Laminate. The MAWP, measured at the top of the vessel, shall not be greater than 15 psig. (2) Without Proof Test of As-Constructed Laminate. The MAWP shall not be greater than 2 psig. (b) Maximum External Pressure 1 (1) With Proof Test of As-Constructed Laminate. The MAEWP shall not be greater than 15 psig. (2) Without Proof Test of As-Constructed Laminate. The MAEWP shall not be greater than 2 psig. (c) Temperature Limits. The design temperature shall be limited to a value for which mechanical properties have been determined by the procedures in paras. 2A-300(b) and 2B-200(a), and the chemical resist- ance has been established by the material selection pro- cess identified in Table 1-1, item 3. Operating temperatures to 180°F maximum are com- monly encountered and a large body of mechanical property and chemical resistance data exists to facilitate design. The design temperature shall not be less than the maximum operating temperature. See para. 3-300. Applications above 180°F require that the designer rec- ognizes and accounts for possible reduced mechanical properties at the elevated temperature and possibly decreasing mechanical properties with time as a conse- quence ofthermal and chemical exposure. Such elevated temperature applications require special design atten- tion, and consultation with the resin manufacturer is essential. 1-200 USER’S BASIC REQUIREMENTS SPECIFICATION It is the responsibility of the User, or an Agent acting onhis/her behalf, who intends thata vessel be designed, constructed,inspected, tested, and certified to be incom- pliance with this Standard, to provide or cause to be provided for such vessel a User’s Basic Requirements Specification (UBRS). The UBRS shall set forth the intended design conditions of the vessel to provide the basis for design and shall identify the external environ- ment to which the vessel will be exposed, the intended function of the vessel, mechanical loads imposed on the vessel, specific installation requirements, and specific codes and laws applicable at the location where the vesselwillbe installed. TheUseralso shallspecifywithin theUBRS thetype ofresinrequired ordefine the contents to which the vessel shall be exposed. See Table 1-1 for User’s Basic Requirements Specification. 1-210 Service Restrictions (a) When a vessel is to be used in a critical service, it shall be the responsibility of the User or the User’s designated Agent to declare such in the UBRS. (b) This Standard provides generalized guidelines to help the User or User’s Agent in determining when a vessel should be declared to be in critical service. How- ever, the User or User’s Agent has sole authority and responsibilityfor suchdeclaration. Anysuchdeclaration made is not a function of the scope, requirements, or content of this Standard, or of any firm or individual (other than the User or User’s Agent) involved in any part of the process of using or determining proper use of the Standard.
