2、 E-mail: standardsmss-hq.org MSS www.mss-hq.org MSS STANDARD PRACTICE SP-60 i This MSS Standard Practice was developed under the consensus of MSS Technical Committees 112 and the MSS Coordinating Committee. The content of this Standard Practice is the resulting efforts of competent and experienced v
3、olunteers 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 Stan
4、dard 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
5、. MSS 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 statem
6、ent. “Unless otherwise specifically noted in this MSS Standard Practice, other standards documents referred to herein are identified by the date of issue that was applicable to this Standard Practice at the date of issue of this Standard Practice (see Annex A). This Standard Practice shall remain si
7、lent on the applicability 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 connectio
8、n therewith. 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 r
9、eferences 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
10、 mandatory requirements. U.S. customary units in this Standard Practice are the standard; the (SI) metric units are for reference only. Substantive changes in this 2012 edition are flagged by parallel bars as shown on the margins of this paragraph. The specific detail of these changes may be determi
11、ned by comparing the material flagged with that in the previous edition.

16、ference 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 bu
17、t 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 and g
18、askets 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 point bet
19、ween 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 Indicates “
20、Nominal Pipe Size” (U.S customary). A standard size identification number, not necessarily an actual dimension. The (SI) metric-based equivalent is called DN or “diametre nominel“. Guidelines for (SI) metric data may be found in MSS SP-86. 2.5 Purchaser The party entering into a contract or agreemen
21、t to purchase products manufactured in accordance with this Standard Practice. 2.6 Tapping Machine A machine (also known as a drilling machine) used to cut a hole into an existing pressurized or non-pressurized main through the use of a tapping sleeve and tapping valve. The tapping machine is equipp
22、ed 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 valve can then be closed to seal the branch connection while the tapping machine is removed from
23、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 valve and tapping machine, without interruption of service. Tapping sleeves can be referenced
24、in MSS SP-111 and MSS SP-124. 2.8 Tapping Valve A special gate valve designed with end connections to provide a waterway opening clearance for tapping operations, as well as proper alignment and positioning of a tapping sleeve, valve, and tapping machine. 2.9 Other definitions may be found in MSS SP
25、-96. CONNECTING FLANGE JOINTS BETWEEN TAPPING SLEEVES AND TAPPING VALVES MSS STANDARD PRACTICE SP-60 2 3. PRESSURE-TEMPERATURE RATING Flange ratings of tapping sleeves and tapping valves covered by this Standard Practice shall be limited to, as applicable, the pressure-temperature rating shown in AS
26、ME 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 connecting joint, shall be in accordance with the dimensions in Tables 1 and 2, respectively. Dimension
27、s 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 125, or AWWA C110/A21.10. 4.3 See MSS SP-113 for dimensions that define the connecting flange join
28、t between tapping machines and tapping valves in sizes from NPS 2 through NPS 60. Note: (a) The flange diameters and bolt hole dimensions of ASME and AWWA flanges are identical in the equivalent sizes. 5. FLANGE ALIGNMENT 5.1 The end flange of the tapping valve which forms a joint with the tapping s
29、leeve 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 flange
30、s 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 s
31、pecial inside diameter may be used; however, it should be noted that a full face gasket may require higher bolt torque for sealing.
