2、E-mail: standardsmsshq.org www.msshq.org MSS STANDARD PRACTICE SP-60i This MSS Standard Practice was developed under the consensus of the MSS Technical Committee 112 and the MSS Coordinating Committee. The content of this Standard Practice is the resulting efforts of competent and experienced volunt
3、eers to provide an effective, clear, and non-exclusive standard that will benefit the industry as a whole. This MSS Standard Practice describes minimal requirements and is intended as a basis for common practice by the manufacturer, the user, and the general public. The existence of an MSS Standard
4、Practice does not in itself preclude the manufacture, sale, or use of products not conforming to the Standard Practice. Mandatory conformance to this Standard Practice is established only by reference in other documents such as a code, specification, sales contract, or public law, as applicable. MSS
5、 has no power, nor does it undertake, to enforce or certify compliance with this document. Any certification or other statement of compliance with the requirements of this Standard Practice shall not be attributable to MSS and is solely the responsibility of the certifier or maker of the statement.
6、“Unless indicated otherwise within this MSS Standard Practice, other standards documents referenced to herein are identified by the date of issue that was applicable to this Standard Practice at the date of approval of this MSS Standard Practice (see Annex A). This Standard Practice shall remain sil
7、ent on the validity of those other standards of prior or subsequent dates of issue even though applicable provisions may not have changed.” By publication of this Standard Practice, no position is taken with respect to the validity of any potential claim(s) or of any patent rights in connection ther
8、ewith. MSS shall not be held responsible for identifying any patent rights. Users are expressly advised that determination of patent rights and the risk of infringement of such rights are entirely their responsibility. In this Standard Practice, all text, notes, annexes, tables, figures, and referen
9、ces are construed to be essential to the understanding of the message of the standard, and are considered normative unless indicated as “supplemental”. All appendices, if included, that appear in this document are construed as “supplemental”. Note that supplemental information does not include manda
10、tory requirements. The U.S. customary units and SI (metric) units in this Standard Practice are regarded separately as the standard; each should be used independently of the other. Combining or converting values between the two systems may result in non-conformance with this Standard Practice. U.S.
11、customary units in this Standard Practice are the default standard, in cases of conflict or incongruity. Substantive changes in this 2017 edition are “flagged” by parallel bars as shown on the margins of this paragraph. The specific detail of the change may be determined by comparing the material fl
12、agged with that in the previous edition. Non-toleranced dimensions in this Standard Practice are nominal unless otherwise specified.

17、terference problems between tapping sleeves and tapping valves through the use of a positioning recess and mating raised face of the connecting flanges between tapping sleeves and tapping valves. The recess and raised face serve to ensure proper alignment of the tapping valve onto the tapping sleeve
18、 but do not affect the strength or the tightness of the joint. 1. SCOPE 1.1 This Standard Practice establishes flange and gasket dimensions which define the interface between tapping sleeves and tapping valves. 1.2 This Standard Practice establishes dimensions for these special connecting flanges an
19、d gaskets of nominal sizes from NPS 2 through NPS 60 (DN 50 through DN 1500) for water and sewerage systems. 1.3 This Standard Practice establishes pressure-temperature ratings for the connecting flanges. 2. DEFINITIONS (Reference Figure 1 Illustration) 2.1 Joint The “interface” or connecting joint
20、between sleeves and tapping valves will be abbreviated as “joint” in this Standard Practice. 2.2 Main A pipe used in a water or sewerage system for distribution of water or collection of sewage. 2.3 Manufacturer The party producing products in accordance with this Standard Practice. 2.4 NPS Indicate
21、s “Nominal Pipe Size” (U.S. customary). A standard size identification number, not necessarily an actual dimension. The European or International designation equivalent to NPS is called DN (diametre nominal/nominal diameter) in which sizes are based on SI (metric) units. Guidelines for SI (metric) d
22、ata may be found in MSS SP-86. 2.5 Purchaser The party entering into a contract or agreement to purchase products manufactured in accordance with this Standard Practice. 2.6 Tapping Machine (also known as a drilling machine) A machine used to cut a hole into an existing pressurized or non-pressurize
23、d main through the use of a tapping sleeve and a tapping valve. The tapping machine is equipped with a cutter, which extends through the waterway of the tapping valve and sleeve branch to cut the hole into the main and remove the cut-out piece (coupon) upon retraction of the cutter. The tapping valv
24、e can then be closed to seal the branch connection while the tapping machine is removed from the valve and the branch pipeline is connected to the tapping valve. 2.7 Tapping Sleeve A fitting that can be assembled onto an existing main to make a branch or “tee” connection to the main with a tapping v
25、alve and tapping machine, without interruption of service. Tapping sleeves can be referenced in MSS SP-111 (Gray-Iron and Ductile-Iron) and MSS SP-124 (fabricated). MSS STANDARD PRACTICE SP-602 2.8 Tapping Valve A gate valve with special end connections that are designed to provide proper alignment
26、of a tapping sleeve, the tapping valve, and tapping machine, so that the tapping machine cutter will pass through the tapping valve and tapping sleeve branch with clearance during the tapping operation. A tapping valve is also specially designed so that its gate opens sufficiently to provide clearan
27、ce for the tapping cutter to pass through the open valve during the tapping operation, and so that there is sufficient distance between the gate and the valves connection with the tapping machine to provide clearance between the gate and the pilot drill and cutter at the conclusion of the tapping op
28、eration, when the cutter is withdrawn and the tapping valve is closed. 2.9 Other definitions may be found in MSS SP-96. FIGURE 1 Tapping Components (For Illustration Only) MSS STANDARD PRACTICE SP-603 3. PRESSURE-TEMPERATURE RATING Flange ratings of tapping sleeves and tapping valves covered by this
29、 Standard Practice shall be limited to, as applicable, the pressure-temperature rating shown in ASME B16.1, Class 125, or the pressure ratings of AWWA C110/A21.10, or AWWA C111/A21.11. 4. FLANGE DIMENSIONS 4.1 The flange of the tapping sleeve and the flange of the tapping valve, which form the conne
30、cting joint, shall be in accordance with the dimensions in Tables 1 and 2, respectively. Dimensions are provided for two types of tapping sleeve/valve connections, Type “M“ and Type “U“. 4.2 Flange diameter and bolt hole dimensions(a)shall be in accordance with the requirements of ASME B16.1, Class
31、125, or AWWA C110/A21.10. 4.3 See MSS SP-113 for dimensions that define the connecting flange joint between tapping machine and tapping valve, in sizes from NPS 2 through NPS 60 (DN 50 through DN 1500). 5. FLANGE ALIGNMENT 5.1 The end flange of the tapping valve which forms a joint with the tapping
32、sleeve must be parallel to and concentric with the opposite flange and concentric with the waterway to provide proper alignment for the tapping operation. 5.2 The raised face of the tapping valve and recess of the tapping sleeve must be concentric with the bolt hole pattern of their respective flang
33、es to provide proper alignment between the tapping valve and tapping sleeve. 6. FLANGE GASKET 6.1 The flange gasket used between the tapping sleeve and tapping valve must have an inside diameter large enough to fit over the raised lip of the tapping valve. 6.2 A ring type or full face gasket with a
34、special inside diameter may be used; however, it should be noted that a full-face gasket may require higher bolt torque for sealing. NOTE: (a) The flange diameters and bolt hole dimensions of ASME and AWWA flanges are identical in the equivalent sizes. MSS STANDARD PRACTICE SP-604 TABLE 1 Recess in
