The tube is malleable, but it should not be bent to many times because it begins to gain curves. We fixed everything with metal fasteners in which we glued what we normally put in the feet of the chairs so as not to damage the tube. The tube should not shake or make sharp curves.
The dangerous part is the part of putting the bicones (part that allows to join of the tube with other pieces) since they have to be well done or gas leaks.
We have chosen to do it differently and not use connecting parts. As only have one gas appliance, the stove, we do not need to split the gas flow, so what we did was connect the copper pipe directly to a gas hose.
In other words, instead of having to connect the copper pipe to a bicone which then allows to connect a gas hose and to have two potential escape sites (side of the pool and side of the stove), we put the tube in the hose 10cm and we put two clamps .
Who works in the area or is accustomed to working with gas and this can do it in a safe way obviously, but in our case the hypothesis of doing something wrong is greater and in this way the risk is almost zero because it is clear that no there are leaks and we are putting copper pipe to gas, inside rubber hose to gas, with appropriate clamps … so we are confident with the choice.
