Just have a question regarding this. Couldn't really find it in the code book.
Commercial building interior concrete wall, can a gas line and water line run through the same hole horizontally? Hole is about 8 inches round. There'll be spacing between the water pipe and the gas piping will be sleeved. Just wasn't sure if the gas pipe needs it's own dedicated hole.
Clause 6.16.6 makes me believe that it can.
Thank you
Using the same hole is fine. There is no sleeve required, you only need to double wrap it with pipe wrap tape. Only CSST needs to be sleeved.
QuoteClause 6.16.9 - When piping or tubing passes through masonry or concrete, the portion of piping or tubing that runs through this material shall be sleeved or double wrapped with a pipe wrap tape.
Pipe wrap tape — adhesive tape made of PVC or polyethylene material with minimum thickness of 10 mil (0.3 mm), with an adhesive resistant to water.
Clause 6.16.6 - To avoid galvanic corrosion, metallic piping or tubing shall be installed in such a manner that it is not in contact with any other dissimilar metallic pipe or structure.
Clause 6.16.7 - When piping or tubing is run in a sleeve, the sleeve shall be of such material and so installed as to protect the piping or tubing from damage and galvanic action.
