1.2.3 Service Conditions. Criteria for selection of fitting types and materials suitable for particular fluid service are not within the scope of this Standard.
1.2.4 Quality Systems. Nonmandatory requirements iclating to the product manulacturers quality system program are described in Nonmandatory Appendix A.
1.2.5 Relevant Units. This Standard states values in both SI (Metric) and U.S. Customary units. These systems of units are to be regarded separately as standard. Within the text, the U.S. Customary units are shown in parentheses or in separate tables that appear in Mandatory Appendix 1. The values stated in each system are not exact equivalents; therefore, it is required that each system be used independently of the other. Combining values from the two systems constitutes nonconformance with the Standard.
Tables 1 through 5 show fittings dimensional requirements in millimeters. Tables I-i through 1-5 show the dimensional requirements for inch dimensioned fittings.
2 PRESSURE RATINGS
2.1 General
Fittings under this Standard shall be designated as Class 2(XXJ, 3000, and 60(X) for threaded end fittings and Class 3000, 6000, and 9000 for socket-weld end fittings.
2.1.1 Basis of Rating. The schedule of pipe corresponding to each Class designation of fitting for rating purposes is shown in Table 7. Design temperature and other service conditions shall be limited as provided by the applicable piping code or regulation for the material of construction of the fitting. Within these limits, the minimum wall thickness for pipe to be used with a Table 7 Class designated fitting shall be computed based on appropriate size straight seamless pipe of equivalent material as the fitting (as shown by comparison of composition and mechanical properties in the respective material specifications). The minimum pipe wall thickness calculation shall include pressure design and all applicable additional allowances (e.g., erosion, corrosion, and thread depth for threaded pipe). The minimum wall thickness for selected pipe, considering manufacturing minus wall thickness tolerance (typically 12.5%), shall not be less than the minimum wall calculation. The fitting is suitable for the application if the wall thickness of the selected pipe equals or is less than the ASME B36.1OM Schedule No. or Wall Designation pipe wall thickness correlated with the fitting in Table 7 Isee Note (1) in Table 71.
2.1.2 Nonstandard Pipe Wall Thickness. Since ASME 1336.IOM does not include Schedule 160 for Double Extra Strong thickness for NPS ‘4 and , the values in Table 8 shall be used as the nominal wall thicknesses of the pipe for rating purposes.
2.1.3 Combination End Fittings. The Class designation for fittings made with combinations of socket- welding and threaded ends shall be based on the end configuration that has the lowest rating from Table 7.
2.2 Pressure Test Capability
Pressure testing is not required by this Standard, but the fittings shall be capable of withstanding a hydrostatic test pressure required by the applicable piping code for seamless pipe of material equivalent to the fitting forging and of the schedule or wall thickness correlated with the fitting Class and end connection of Table 7.
