STANDARJIPRACTICE
SP-8C
2. PRESSURE-TEMPERATURERATINGS Pressure-temperature ratings for solder ts made with typical commercial solders are given in Annex A (Table X1-1 in Appendix Xi). It shall be the responsibility ofthe to select a solder composition that is compatible with the service conditions, as well as to assure the adequacy of workmanship employed in making thets.
2.1 The pressure-temperature ratings in Table 1 (Table Xi-2) apply to all products governed by this Standard Practice. Valves conforming to the requirements ofthis Standard Practice shall, in all respects, merit these ratings.
2.2 These ratings are the maximum allowable, nonshock pressures at the temperatures shown, and allowable pressures may be interpolated between temperatures shown.
2.5 The ratings given in Table 1 at -20°F(-29OC) to 1 50°F (66OC) shall also apply at lower temperatures. Products that are to operate at low temperatures shall conform to the rules of the applicable codes under which they are to be used.
2.3 The temperature shown, corresponding to the pressure rating, shall be the material temperature of the pressure retaining structure (the temperature rating). In view of the various environments in which piping components may be installed (i.e., insulated or not, and either heated or cooled), it is assumed that the material temperature of the pressure retaining structure is the temperature of the contained fluid. Use of a pressure rating at a material temperature other than the temperature of the contained fluid is the responsibility of the , and subject to the requirements of applicable codes.
--`,,,,,-`-`,,`,,`,`,,`---
2.4 The safe pressure-temperature rating of a solder-t piping system is dependent, not only on valve, fitting, and tubing strength, but also on the composition of the solder used for ts.

2.6 The safe pressure-temperature rating of valves fitted with non-metallic discs, (Le., globe and angle valves, Type 2, and check valves, Types 2 and 4) is dependent upon the composition ofthe disc material. It shall be the responsibility of the to speciQ the service application. When no service application is specified, discs suitable for steam service at rated working conditions shali be furnished in all bronze globe and angle valves, Type 2, and in all bronze check valves, Types 2 and 4. s are advised to consult with the manufacturer in cases of doubt.

STANDARDPRACTICE
MSS
3. MATERIALS
SP-80
4.2 Flow age Area
3.1 General - All valve components manufactured to this Standard Practice shall be made from materials produced under recognized quality control procedures. Recommended materials are listed in Table 2.
4.2.1 The flow ageway of bronze gate valves shall have a minimum area of not less than the area of a circle having a diameter equal to the nominal pipe size except that valves fitted with seat rings may reduce the ageway area by the area of the seat ring driving lugs. The valve shall be so designed that the stem andor wedge clear the waterway when the valve is fully open.
3.2 Castings - All castings shall be clean and sound, without defects which will impair their service. No plugging, welding, repairing, or impregnating is allowed.
4.2.2 The flow ageway of bronze globe and angle valves, Types 1 and 2, designed with integral seats and when fully opened, shall have an area at all points equal to the area of a circle having a diameter equal to the nominal pipe size, except the area through the seat may be reduced by the area of the disc guides.
3.3 Corrosion - s are cautioned against application with fluids that may react chemically with any material used in these valves. In certain areas of the country, where water conditions are particularly “aggressive”, piping components made from certain zinc-bearing copper-base alloys are susceptible to a form of corrosion known as dezincification. Consultation with the manufacturer is advised to determine suitability in cases of doubt.
4.2.3 The flow agew,ay area of bronze globe and angle valves, Type 3, of the full flow design, may be reduced by the area of the seating driving lugs.
4. DESIGN
4.2.4 The flow ageway of bronze globe and angle valves, Type 3, ofthe plug design, for throttling service, may have a reduced area through the seat.
4.1 General - Valves shall be of substantial construction to resist permanent distortion under normal service conditions and shall be free of imperfections and defects which may be injurious to the performance of the valve.
4.2.5 The flow ageway of bronze check valves, Types 3 and 4, shall have a minimum area of not Jess than the area of a circle having a diameter equal to the nominal pipe size except that valves fitted with seat rings may reduce the ageway area by the area of the seat-ring driving lugs.

O. PURPOSE

STANDARJIPRACTICE
SP-8C
2. PRESSURE-TEMPERATURERATINGS Pressure-temperature ratings for solder ts made with typical commercial solders are given in Annex A (Table X1-1 in Appendix Xi). It shall be the responsibility ofthe to select a solder composition that is compatible with the service conditions, as well as to assure the adequacy of workmanship employed in making thets.
2.1 The pressure-temperature ratings in Table 1 (Table Xi-2) apply to all products governed by this Standard Practice. Valves conforming to the requirements ofthis Standard Practice shall, in all respects, merit these ratings.
2.2 These ratings are the maximum allowable, nonshock pressures at the temperatures shown, and allowable pressures may be interpolated between temperatures shown.
2.5 The ratings given in Table 1 at -20°F(-29OC) to 1 50°F (66OC) shall also apply at lower temperatures. Products that are to operate at low temperatures shall conform to the rules of the applicable codes under which they are to be used.
2.3 The temperature shown, corresponding to the pressure rating, shall be the material temperature of the pressure retaining structure (the temperature rating). In view of the various environments in which piping components may be installed (i.e., insulated or not, and either heated or cooled), it is assumed that the material temperature of the pressure retaining structure is the temperature of the contained fluid. Use of a pressure rating at a material temperature other than the temperature of the contained fluid is the responsibility of the , and subject to the requirements of applicable codes.
--`,,,,,-`-`,,`,,`,`,,`---
2.4 The safe pressure-temperature rating of a solder-t piping system is dependent, not only on valve, fitting, and tubing strength, but also on the composition of the solder used for ts.

2.6 The safe pressure-temperature rating of valves fitted with non-metallic discs, (Le., globe and angle valves, Type 2, and check valves, Types 2 and 4) is dependent upon the composition ofthe disc material. It shall be the responsibility of the to speciQ the service application. When no service application is specified, discs suitable for steam service at rated working conditions shali be furnished in all bronze globe and angle valves, Type 2, and in all bronze check valves, Types 2 and 4. s are advised to consult with the manufacturer in cases of doubt.

STANDARDPRACTICE
MSS
3. MATERIALS
SP-80
4.2 Flow age Area
3.1 General - All valve components manufactured to this Standard Practice shall be made from materials produced under recognized quality control procedures. Recommended materials are listed in Table 2.
4.2.1 The flow ageway of bronze gate valves shall have a minimum area of not less than the area of a circle having a diameter equal to the nominal pipe size except that valves fitted with seat rings may reduce the ageway area by the area of the seat ring driving lugs. The valve shall be so designed that the stem andor wedge clear the waterway when the valve is fully open.
3.2 Castings - All castings shall be clean and sound, without defects which will impair their service. No plugging, welding, repairing, or impregnating is allowed.
4.2.2 The flow ageway of bronze globe and angle valves, Types 1 and 2, designed with integral seats and when fully opened, shall have an area at all points equal to the area of a circle having a diameter equal to the nominal pipe size, except the area through the seat may be reduced by the area of the disc guides.
3.3 Corrosion - s are cautioned against application with fluids that may react chemically with any material used in these valves. In certain areas of the country, where water conditions are particularly “aggressive”, piping components made from certain zinc-bearing copper-base alloys are susceptible to a form of corrosion known as dezincification. Consultation with the manufacturer is advised to determine suitability in cases of doubt.
4.2.3 The flow agew,ay area of bronze globe and angle valves, Type 3, of the full flow design, may be reduced by the area of the seating driving lugs.
4. DESIGN
4.2.4 The flow ageway of bronze globe and angle valves, Type 3, ofthe plug design, for throttling service, may have a reduced area through the seat.
4.1 General - Valves shall be of substantial construction to resist permanent distortion under normal service conditions and shall be free of imperfections and defects which may be injurious to the performance of the valve.
4.2.5 The flow ageway of bronze check valves, Types 3 and 4, shall have a minimum area of not Jess than the area of a circle having a diameter equal to the nominal pipe size except that valves fitted with seat rings may reduce the ageway area by the area of the seat-ring driving lugs.

APPENDIX XI Metric References This Appendix is supplementary and does not include mandatory requirements.
STRENGTH OF SOLDER TS Extracted from American National Standard - ASME B 16.18. The maximum recommended pressure-temperature limitations for solderts made with copper tube and cast copper alloy fittings, using representative commercial solders, are listed below. Note:
For working temperatures, in the -1 8OC to -29OC range, it is recommended that a t material melting at or above 538OC be employed.
CAUTION:
When soldert valves are used, these ratings will be the lowest value of Table X1-1 or Table X1-2. Also refer to Section 2.4.
