11.6 laws and regulations 11.1 delivery forms shielding
gas
es can be delivered in different forms. aga delivers shielding
gas
es mainly in the following ways: 1. in
gas
eous form (carbon dioxide in liquid form) in
cylinder
s
. the most common
cylinder
sizes are 50 l/200 bar and 20 l/200 bar. smaller
cylinder
sizes are also included in aga’s rental system. the selection of
cylinder
sizes depends on the type of the shielding
gas
. 2. in
gas
eous form (carbon dioxide in liquid form) in
cylinder
bundles, maxi
cylinder
s
or supermaxi
cylinder
s
. a
cylinder
bundle comprises 12
cylinder
s
with a fixed connection to
gas
output, while maxi and supermaxi
cylinder
s
are round tanks (450 and 800 l). the availability of maxi and supermaxi
cylinder
s
depends on the
gas
type. bundles, maxi
cylinder
s
and supermaxi
cylinder
s
can be transported with a forklift. this delivery form is suited to medium-large customers with a
gas
delivery network. 3. in liquid form to tanks on the customer’s premises. liquid argon (lar), liquid mison ® (lar + 0.03 no) or liquid carbon dioxide (lic) is transported in a tanker truck to the customer’s tank, from which it is conducted to the
gas
network via an evaporator. this delivery form is suited to customers with very high
gas
consumption. 11.1.1 a
gas
gas
distripution systems many of our customers currently use a
gas
distribution system comprising a
gas
manifold (reduces the
cylinder
pressure to network pressure), cylin- ders or
cylinder
bundles connected to it, a
gas
network and the required number of tapping points. several different types of
gas
manifolds are available depending on the
gas
,
gas
requirement and the desired level of automation. if the
gas
consumption is very high, the
gas
can be delivered in liquid form. the
gas
will then be fed from the liquid
gas
tank to the
gas
network via an evaporator, and further to the point of use from the tapping points. the delivered
gas
es can also be mixed into the desired mixture using a mixer before it is conducted to the
gas
network. a
gas
distribution system guarantees a reliable and continuous
gas
supply to different points of use.
gas
cylinder
s
do not need to be moved at the worksite, which saves time and work, and improves safety. a
gas
distribution system also reduces the amount of
cylinder
s
needed and lowers rental and transportation costs. in order to ensure correct operation, the design and implementation of the
gas
distribution system should be commissioned from a company spe- cialising in the installation of
gas
networks. aga has long experience in the design and implementation of functio- nal
