5.5.
Valve connection to piping
The connections should be 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.
Note
See chapter 3.3. Description and components location, page 19 to identify the connections.
5.5.1. Top-mounted valve installation
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.
In addition, 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.
•
The diagrams above illustrate how the flexible piping connection should be mounted;
•
in order to adequately compensate the tank elongation the flexible piping must be installed
horizontally
;

Support to the wall
