ASME B16.26:2018 pdf free download.Cast Copper Alloy Fittings for Flared Copper Tubes.
2.5 Service Conditions
Criteria for selectrnn of materials suitable for particular fluid service are not within the scope of this Standard.
3 PRESSURE RATINGS
The fittings covered by this Standard are designed for a maximum cold-water service pressure of 1 200 kPa (175 psig).
4 SIZE
The sizes of the fittings shown in Table 7.1-1 correspond to standard water tube size as defined in ASTM B88.
5 MARKING
Each fitting shall be marked with the manufacturer’s name or trademark and other applicable markings as required by MSS SP-25. Marking of fittings less than nominal size ‘, is optional.
Fittings manufactured from cast copper alloys containing silicon shall be permanently marked with the designation Si.
Fittings manufactured from cast copper alloys containing bismuth shall be permanently marked with the designation B or Bi.
6 MATERIAL
(a) Castings intended for use in applications up to 204°C (400°F) shall be of a copper alloy produced to meet
(1) the requirements of ASTM B62 for copper alloy LJNS No. C83600, or
(2) the chemical and tensile requirements of ASTM B584 for copper alloy tiNS No. C83800 orC84400 and in all other respects comply with the requirements ofASTM B62
(b) Castings intended for use in potable water applications up to 93°C (200°F) shall be low lead (0.25% or less) and shall be
(3) of a copper alloy produced to meet the requirements of ASTM B584 for copper alloy UNS No. C87850 or C89833, or
(4) of other cast copper alloys, provided the fittings produced meet mechanical and corrosion-resistant properties needed for potable water application
7 DIMENSIONS
7.1 Fitting and Nut
The dimensions and tolerances of fittings and nuts shall be as shown in Table 7.1-1. Design of the sealing surfaces of the fitting and nut shall be at the discretion of the manufacturer.
7.2 Tube Flare
Dimensions relating to the flared end of the tube aredescribed in Nonmandatory Appendix ATable A-1.
