The need
Normally, it is possible to assemble a chain without the need for extension units.
But, in cases where a large and relatively straight distance is required, these units can be used to minimize pressure drops as well as expenses.
The end units of these assemblies should be purchased through Smartec’s distributors. The pipe should be purchased through the local supplier.

Pipe Type
We recommend using seamless stainless steel Schedulues 80 or Schedulues 40 pipes.
In certain cases (mainly in the CH03E assembly) copper piping can also be used. Schedulues 80 is good for working at high pressure values and mechanical bending efforts of the piping, Schedulues 40 is slightly better at avoiding pressure loses (larger internal diameter). Normally use Schedulues 80.
When cutting the piping (to produce the screws), consider the length of the screws and add it to the total length of the required extension.

For optimal performance use seamless stainless steel (304, 316). A non-stainless-steel material may cause corrosion that will block the passageways and Jets which leads to a significant decrease in performance. If necessary, the pipe can be slightly bent using dedicated equipment.

“G” Thread
BSPP thread is often referred to as “G” threads, the two types of thread are the same parallel straight. During the production of the screws, make sure that there are no chips in order to prevent Jet blocking.

Notes
It is recommended to use sealing means while assembling the pipe at the end parts.
The rear parts (R) and the pipe can be used for connecting Jets without the chain, direct connection.
You can use copper piping but pay attention to possible damage especially in the screw’s areas.
It is recommended to use copper piping only in cases where there is no other choice.
