ASTM F681-82(2014)

Standard Practice for Use of Branch Connections

ABSTRACT
This practice lists commonly used types of branch connections for carbon steel, chromium-molybdenum steel pipe and copper-nickel alloy tubing. The branch to run size applications are presented in details. The weld joint designs, fabricated branch connections and threaded fittings shall meet the requirements prescribed.
SCOPE
1.1 This practice lists commonly used types of branch connections for carbon steel, chromium-molybdenum steel pipe and copper-nickel alloy tubing. Branch to run size applications are given in Table 1, Table 2, and Table 3. Other types of branch connections (Fig. 1) may be used provided they comply with the requirements of Title 46 CFR Subparts 56.07-10(f) and 56.70-15(g) of the USCG Regulations.
