Bypass configuration
Manifold configuration
• The diagrams above illustrate how the flexible piping connection should be mounted;
• in order to adequately compensate the tank elongation the flexible tubes must be installed horizontally;
• should the flexible piping connection be installed in vertical position, instead of compensating the elongation, it will create
additional stresses on the valve & tank assembly. Therefore this is to be avoided;
• the flexible piping connection must be also be installed stretched, avoiding excessive length. For instance 20 - 40 cm is
enough;
• excessively long and non-stretched flexible piping connection will create stresses on the valve and tank assembly when the
system is pressurized, as illustrated in the next picture: on the left the assembly when the system is unpressurised, on the
right the flexible piping connection when put under pressure tends to lift up the valve when stretching up. This configuration
is even more dramatic when using semi-flexible piping;
• failure to provide enough vertical compensation may lead to different kinds of damage, either on the valve thread which
connects to the tank, or on the female thread connection of the tank that connects to the valve. In some cases, damage may
also be seen on the valve inlet and outlet; connections;
