The branch joints come in different pipe diameters, which
can be easily matched with different pipe diameters.
When connecting pipes, select the pipe section with the
appropriate pipe diameter, cut it in the middle with a pipe
cutter and remove burrs, as shown in the figure below.
Middle of the pipe section
Use special pipe cutter
The length of the straight pipe section between the
continuous branch pipes shall be no less than 500mm.
The straight pipe section behind the branch pipe end
shall be no less than 500mm. The length of straight pipe
between two right angle bends shall be no less than
500mm.
