MSS STANDARD PRACTICE SP-45

FOREWARD

The 1953 edition ofMSS SP-45-1953 B}'passand Drain Connection Standard Prac:ttct was a combination of two fonne r MSS Standard Practices; MSS 8P-5-1944 By-Pass Size Standard Practice and MSs..SP-2S- J943 Drain Tapping Standard Practice. As the subject maner of these two Standard Practices is so closely related they were combined as a convenience to the user.

MSS SP-S was originally adopted in 1924 and applied to steel gate valves only. Bosses on steel castings cftha! period presented a mort complex problem than castings of other metals and the diversification of requests in regard to size, location, and number of bosses on the part of users prompted the MSS to iniliate a standardization program on the subject. The original Standard Practice established the number of bosses, minimum O.D. of boss, and the pipe thread size for steel gate valves in sizes 3 to 24 inch inclusive. The bosses were intended to be used for both bypass and drain connections.

In 1937 a new edition ofSP-5 was adopted. This edition was greatly expanded over the original and included both cast iron and steel valves in the ~ate, ~ Iobe and angle patterns. The subiect matter was confined to by-passes only and standard locations were established for the bypass on each type of valve Two sets of bypass sizes were establishcd; one for the purpose of warming up main lines before opening the main valve and one for the purpose of balancing the pressure on both sidcs of the main valve to facilitate its operation. The edition has been reaf· finned periodically up to the promu lgation of the new MSS SP-45 .

MSS SP-28 was originally adopted in 1937 and was also prompted by the variety of user requests for connections on valves and fittings at odd locations and varying sizes, with and without bosses. SP-28 cstablished standard drain sizes for each size valve and fitting, standard maximum sizes for unbossed tappings and standllrd locattons with standard symbols to designate the location. MSS SP-28 was revised in 194 5 at which timc a standard method of designating openings of reducing finings was added. This Standard Practicc was also periodically reaffinned.

The 1953 edition of MSS SP-45 combined these two Standard Practices so that the user has all information pertaining to bypass and drain connections in a single document. In this edit ion the newer methods of making attachments, such as butt-weld have been recognized.

The 1971 edition expanded the coverage ofthe documeflt by including coverage ofbaJl valves. In preparing this edition, the entire Standnrd Practice was reviewed and up-dated to keep pace with the expanding technology.

The 1976 edition expanded the coverage of the bypass sizes to include valves through NPS 48 and the document has been metricized.

The 1982 edition expanded the coverage of the document to include plug valves.

The 1987 edition was a reaffirmation of the 1982 edition with no substantive change.

The 1992 edition changed the title, removed metric units, and made several editorial changes.

The 1998 edition added metric units and made several editorial and format changes.

The 2003 editton was issued with only editorial changes .

c"W''''''

1.1 This Standard Practice establishes rlXjuirements for conne<:lions to valves and fittings to accommodate drains and bypasses in all pressure classes.

1.2 Specific requirements are:

.j Standard symbols and locations of openings for drains and bypasses.

b) Standard size of drains and bypass • openmgs.

c) Minimum thread lengths in drain and bypass toppings.

d) Minimuln diameter and depth of socketwcld connection for drain and bypass.

e) Buu.welding connection for drain and bypass.

f) Bosses for drain and bypass connee tion.

g) Method for designating outlets of reducing fittings .

2.1 Figures 5 and 6 illustrate the application of standard symbols for the locations of openings for drain and bypass connections recognized as standard. These symbols should be regularly employed on drawings. specifications requisitkms, and other instruments used in the transactions of business.

,,,,, ' .. ... ..-_--1

2.2 When a tap is required at some other localion, it is recommended that the manufacturer be con· sulled as to their practicability, and both the inquiry and the order should be accompanied by a skelch indicalingthe location upon Ihe filling or valve body.

3. STANDARD DRAIN SIZES

3.1 When fittings and valves require dmin open· ings, they are regularly furnished with the size shown in Table I unless otherwi se spec ified by purchaser.

.5 . BYPASS LOCATIONS

S. I Galt Valves When gate valves are ordered with bypass attached, it shall be standard practice to attach the bypass at the side of the main valve with the siems of both valves pointing upward. The more common of the "Special" auached locations is on the center of the flow line, al the bottom of lhe main valve, (see Figure 5 locations C & D) with the stem of the bypass valve at righl angles to the main valve stem. This is designated as the "bottom attachment,." or defined as "bypass at the bottom." When any other"spccial attached location" or other position of the bypass valve stem is desired, a sketch should be sent to the manufacturer.

'''''' ' ..... _----

5.2 Globe Valves When globe valves are ordered with bypass attached, it shall be regular practice to attach bypass at the right-hand side of the main valve, (see Figure 5 locations E & F) with the stems of both valves parallel, pointing vertically upward . When bypass may be "specially" required attached at the left-hand side, (see Figure 5 locat ions A & B) the designation shall be "left-hand attachment." Righthand side of a globe valve is the side at the right, when facing the flow port which leads to the underside ofthc disc,

5.3 Angle Valves When angle valves are ordered with bypass attached, it shall be regular practice to attach bypass at the back of the main valve, (see Figure 5 locations E & F) with the stems of both parallel, pointing vertically upward. When bypass may be "specially" required attached at the righthand or left-hand side, (see Figure 5 locations C & o and A & B respectively) the designation shall be "right-hand attachment" Of' " left-hand attachment," Right-hand side of an angle valve is at the right, when facing the back of the valve.

5.4 Check Valves When check valves arc ordered with bypass attached, it is standard practice to attach the bypass at the side of thc check valve so that the bypass valve stem and the check valve cap both point upward. Iflocalion of bypass is important its location should be specified according 10 Figure 5.

5.5 Ball Valva When ball valves arc ordered with bypass attached, it shall be standard practice 10 attach the bypass at the side of the main valve with the stems of both valves pointing upward. If localion of bypass is important its location should by specified accord ing to Figure 5.


MSS STANDARD PRACTICE SP-4S

5.6 Plug Valves When plug valves are ordered with bypass attached, it shall be standard practice to attach the bypass at the side of the main valve with the stems of both valves pointing upward. If the main valve should have a handwheel on the side of the valve, the bypass, where possible, should be located on the handwheel side. Ifany other location is required, position should be specified according to FigureS .

6. DRAIN & BYPASS CONNECTION DIMENSIONS

6.1 PiJn Threads Pipe threads shall be tapered pipe threads in accordance with ASME B1.20.1. Metal thickness shall be sufficient to allow the ef

fective thread length specified in Table 3. These lengths are equal to the effective thread lengths of tapered external pipe threads, ASM E 81.20. l. Where wall thickness is insufficient or the tapped hole needs reinforcemenl, a boss is required.

6.2 Sockets Sockets (socket.welding) may be provided in the wall of a fitting or valve if the metal thickness is sufficient to allow the depth of socket specified in Table 3. Where the wall thickness is insufficient, or the size of socket requires opening reinforcement, a boss is required.

NQre " L" is eqUid to the effettive thread length of American National Standard external pipe threads. ASME B 1.20.1

6.3 Bun Welds Connections may be made by bun·weldingdirectly to the wall of the fitting or valve, see Table 3.

7. BOSSES

7. J When a boss is required to meet the thicknesses in Table), the diameter shall be not less than those shown in Figurc4.

8. REDUCING FJITJNGS

8.1 When a drain opening is required on the side of a reducing fitting whose side is tapered, the axis of the drain opening should be at right angles to the centerline of the fitting.

8.2 The size of the drain opening on a reducing fitting shall be governed by the size of the adjacent outlet.

8.3 When a tap is required on a reducing fitting at a point centrally located, such as "G" on a reducer, its size shall be governed by the average of the drain openings which would be used for the largest and smallest outlet. using the drain opening size which is standard, or the next smaller size as shown in Table I .
