INSTALLATION INSTRUCTIONS FOR BAKER SERIFS 200 COUPLINGS
July 1992
!. Measure pipe diameter at 8 places 45 deg. apart. Difference between minimum and maximum should not
exceed *(C) . ff the difference is greater than (C), make correc__i_ions by rounding up the pipe with trench jacks,
or suitable wooden post and wedges. Maintain this roundness until the joint is made up, and all torqueing
has been completed.
*-Refer to TABLE ON PIPE END TOLERANCES on Page Two.
2. Pipe ends must be clean and free of all oil, dirt, loose scale & rust. A thorough dearsing with a wire brush
is recommended. All welds on pipe ends must be ground smooth.
ASSEMBLY:
i. Place a end ring on each pipe end. If the end ring(s) does not easily slip on pipe, correct pipe out-of-
roundness with jacks or posts as noted above in I.
2. The gaskets should be cleaned and inspected for any damage in shipment, and then stretched over pipe
ends. It may be helpful to wet the gaskets with water to make installation easier.
3. Place the center sleeve on one pipe end. Place gasket and other end ring on the other pipe end. Slide the
center sleeve into position and center over gap between the two pipe ends.
4. IMPORTANT: The clearance between the OD of the pipe ends and the ID of the center sleeve and
end rings is to be distributed as evenly as possible. No more than I/8" ~ or opesainf is permi-.~ible. Wooden
wedges or plastic shims may be used. These centering aids may be removed after the coupling is assembled.
The wedges or shims must not project into the gasket pocket.
5. Be sure that the gasket pocket in the end ring(s) is free from wood, dirt, metal or other ~dd debris.
6. Apply *flax soap to the gasket and center sleeve bevel face, and push gaskets into place. (In winter, use
ethylene glycol mixture). *Pipe joint Lubiicant, Secord Corp, Camden, NJ, or equal.
7. Push end rings against gasket, and rotate one end ring until bolt holes line up.
!. Insert all bolts, tighten nuts finger tight. It is convenient to tighten bolts by downward wrenching. Insert
bolts so nuts are on the !eft side of the installer, as he faces the pipe. STAINLESS STEEL NUTS SHOULD
BE FIELD LUBRICATED WITH A SUITABLE ANTI GALLING COMPOUND PRIOR TO BOLT
TIGHTENING.
2. Be certain that the end ring(s) is started over the center sleeve without any interferenee. If necessary,
wedges may be used to free the end ring(s) from the edge of the center sleeve.
BOLTED SLEEVE TYPE COUPLINGS DO NOT PROVIDE PROTECrIO N A GAINST PULLOUT OF PIPE.
(2)
3. On couplings 60** and larger, 3 or 4 installers can best tighten. Space the installers equally around the
coupling, and have all advance in the same direction as they tighten each nut. Be certain that the end ring
does not "cock" as the nuts are tightened. A torqlleahwdlhla wrm4, eatsst be p.ml. Tighten to 30-35 foot
pounds all around, two or three times. Increase the wrench setting to 40-50 foot pounds, and continue the
procedure to 75 foot pounds for 5/8" belts and 90 foot pounds for 3/4" and larger belts. At the maximum
tightness, go around the coupling several times to assure uniform gasket pressure.
4. Before final tightening, it is good technique to strike each belt head with a light Sledge hammer to seat
all parts.
5. AFTER FINAL TIGHTENING HAS BEEN COMPLETED, remove all pipe roundup material.
RETIGtFFENING OF BOLTS: After 24 hours, or just before filling with water, it may be necessary to check
the tightness of the belts. Follow the last torque setting as shown abeve.
TESTING: !f leaks devdope during the test procedm~, tightm as necessary to stop leaks. Cautionshould
be exercised to assure lhat end ring, emter sleeve or the boiling hardware is not ovt, nd~c.ucd during this
CAUTION: A pipe section should never be allowed to HANG in the coupling. either before or after making
up the joint. Couplings are designed to FLOAT on the pipe ends. not support the pipe.
PIPE END PREPARATION: The pipe shall he sufficiently free from indentations, projections, or roll marks
for a distance 18" from the end of the pipe to make a tight joint with the rubher gasket type of coupling. For
a distance of 18" from the end of the pipe, the pipe circumference shall not he more than (A) largeror (B)
smaller than the outside circumference computed from the specified outside diameter. All of the out-of-
roundness shall he in the form of a smooth oval that can he jacked round in such a manner that the difference
between the maximam and minimum diameters shall not exceed (C) .
