Additional Instructions For B-Series
1. Leave protective wrappers on sleeves until ready to arc
weld.
2. When removing protective wrappers, avoid tearing as
wrappers must be inserted in sleeves after welding and
before caplugs are installed as shown.
3. Cut or fold protective wrapping paper same length as
the sleeve (splice sleeve original wrapping.)
4. Insert paper into sleeve with unprinted side out.
5. Place O.D. sleeve cap caplug over sleeve and tap hole
caplug in tap hole (and vent hole plug in vent hole if
required). See table in catalog for proper part number.
6. Caplugs must be kept tightly in place until removed for
splicing bar in sleeve.
7. As an additional precaution against moisture, it is
suggested that polyethylene sheet, tarpaulins, building
paper or other protective cover be used to cover sleeves
after welding and until they are spliced.
8. If CADWELD ® splicing of the welded assembly will not
occur for a week or more, it is recommended that the
metal O.D. end cap be placed over the end of the sleeve
and secured with all weather pipe tape to hold it in
position. The metal end cap will protect against dislodging
or puncturing of the plastic O.D. caplug.
9. When ready to complete the connection of rebar to the
sleeve, remove end caps, plugs, paper and flame dry
sleeve thoroughly.
NOTES:
1. O.D. sleeve cap caplug, tap hole caplug, and paper must
be placed in sleeve as soon as sleeve has cooled after
welding to effectively prevent internal rusting.
2. Part numbers for these accessories are listed in the
catalog. See catalog for additional information.
Welding of Splice Sleeves to Structural Steel
Splice sleeves are generally arc welded to the structural steel in
a fabricating shop. The design of the weld, the selection of
the electrode, etc. depend on the chemical and physical
properties of the structural steel to which the splice sleeves
are welded. The engineer designing the assemblies should
refer to the pertinent codes and recommended practices of
the American Concrete Institute, American Welding Society,
etc.
Care of Finished Assemblies
Following the instructions on this page, CADWELD ® B-Series
sleeves welded to the finished assemblies are covered to inhibit
rusting and foreign contaminants from entering the sleeve
interior.
