STANDARD PRACTICE
MSS
SP-80
This MSS Standard Practice was developed under the consensus of the MSS Technical Committee 203 and the
MSS Coordinating Committee. The content of this Standard Practice is the result of the efforts of competent and
concerned volunteers to provide an effective, clear, and non-exclusive specificationthat will benefit the industry
as a whole. This MSS Standard Practice is intended as a basis for common practice by the manufacturer, the
user, and the general public. The existence of an MSS Standard Practice does not in itself preclude the manufacture, sale, or use of products not conforming to the Standard Practice. Mandatory conformance is established
only by reference in a code, specification, sales contract, or public law, as applicable.
Unless otherwise specifically noted in this MSS SP, any standard refemd to’herein is identified by the date of
issue that was applicable to the referenced standard(s) at the date of issue of this MSS SP. (See Annex C.)
U.S. customary units in this SP are the standard; the metric units are for reference only.
This document has been substantially revised fiom the previous 1997edition. It is suggested that if the user is
interested in knowing what changeshave been made, that direct page by page comparison should be made of
this document.

STANDARJIPRACTICE
SP-8C
2. PRESSURE-TEMPERATURERATINGS
Pressure-temperature ratings for solder joints made
with typical commercial solders are given in Annex
A (Table X1-1 in Appendix Xi). It shall be the responsibility ofthe user to select a solder composition
that is compatible with the service conditions, as well
as to assure the adequacy of workmanship employed
in making thejoints.
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 user, and subject to the requirements of applicable codes.
--`,,,,,-`-`,,`,,`,`,,`---
2.4 The safe pressure-temperature rating of a
solder-joint piping system is dependent, not only on
valve, fitting, and tubing strength, but also on the composition of the solder used for joints.

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 user 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. Users are advised to consult
with the manufacturer in cases of doubt.

STANDARDPRACTICE
MSS
3. MATERIALS
SP-80
4.2 Flow Passage 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 passageway 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 passageway 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 passageway 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 - Users 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 passagew,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 passageway 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 passageway 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 passageway area by the
area of the seat-ring driving lugs.

This Annex is an integral part of this Standard Practice and is plaied after the main text for convenience.
Extracted from American National Standard ASME B 16.18.
The maximum recommended pressure-temperature limitations for solderjoints made with copper tube and cast
copper alloy fittings, using representative commercial solders, are listed in the table below.
NOTE: For working temperatures, in the OOF to -20°F range, it is recommended that a joint material melting at
or above 1OOO°F be employed. (c)
CAUTION: When solder-joint valves are used, the rating will be the lowest value of Table 1 (Table Xl-1)or
Table Al (Table X1-2). Also refer to Section 2.4.

This Appendix is supplementary and does not include mandatory requirements.
STRENGTH OF SOLDER JOINTS
Extracted from American National Standard - ASME B 16.18.
The maximum recommended pressure-temperature limitations for solderjoints 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 joint material melting
at or above 538OC be employed.
CAUTION:
When solderjoint valves are used, these ratings will be the lowest value of Table X1-1 or
Table X1-2. Also refer to Section 2.4.

Notes: (a) For lower temperatures, See Section 2.5
(b) P-T Ratings - ASME B16.24
(c) Refer to Section 2.4 for safe P-T rating for solder-joint systems.
(d) Some codes (I.E. - ASME BPVC, Section I) Limit the rating temperatures of the indicated m,aterial
to 208OC.
(e) Alternate ratings for valve size DN 6 - DN 50 having threaded ends and union ring body-bonnet joints.
