SUGGESTED SPECIFICATION

ASME B31.9 CODE FOR PRESSURE PIPING, Section 930.2 Mechanically Formed Extruded Outlets in Copper Tube

The approval is subject to the following additional conditions:

1. Mechanically formed extruded outlets shall be perpendicular to the axis of the run tube (header). They shall be formed by drilling a pilot hole and drawing out the tube surface to form a collar having a height of not less than three times the thickness of the branch wall.
2. Branch tubes shall not restrict the flow in the run tube. To ensure this by conforming the branch tube to the shape of the inner curve of the run tube, a dimple / depth stop shall be formed in the branch tube to ensure that penetration into the collar is of the correct depth.  For inspection purposes, a second dimple shall be placed 0.25 inch above the first dimple. Dimples shall be aligned with the tube run.
3.  Branches can be formed up to the run tube size as shown in ASTM F 2014. Forming procedures shall be in accordance with the tool manufacturer’s recommendations.
4. Joints shall be made with the use of approved brazing alloys BCup2 thru BCup5 (0-15% silver content). brazed with a filler that has a melting point above 540 deg Centigrade ( 1000 deg F). Soft soldered joints are not allowed.
5. K, L, M and DWV copper types allowed.
6. Soft and Hard copper allowed.
7. Each model used for making branch connections shall be permanently marked with manufacturer’s name and appropriate model number.
8. Mechanically formed extruded outlets can (but not limited to) be used on commercial and residential buildings.
9. Fitter / Plumber shall be trained and certified to operate the equipment.
