Valve connection to piping
The connections should be hand tightened using PTFE (plumber’s tape) on the threads if using the
threaded connection type.
In case of heat welding (metal type connection), the connections should not be made to the valve
when soldering.

See chapter Components description and location [
connections.
When pressurized, any composite tank will expand both vertically and circumferential. In order to
compensate the vertical expansion, the piping connections to the valve must be flexible enough to
avoid overstress on the valve and tank.
5.5.1
Top-mounted valve installation
The valve and tank should not be supporting any part of the piping weight. This is hence
compulsory to have the piping fixed to a rigid structure (e.g. frame, skid, wall…) so that the weight
of it is not applying any stress on the valve and tank.
