Industrial hoses and connecting fittings.

This mail is to update some news on Nitrogen hose incidents and
recommendations in specifying the same in utility stations. Take note
of the importance of specifying the NRV / Check valve in nitrogen
hose assembly. This is true for steam also for the reason that these
two utilities are used for chemical and alkaline and acidic purging
and cleansing. Also the importance of the right class of jacket to be
worn during such U-station operation.

You can find more hose stories by searching for 'hose rupture'
or 'hose failure'.

Additional the crowfoot or the clawtype coupler is being recommended
for Air and water services rather than the past camlever couplings due to
the flexibility and tightness in its design and without any rubber
sealing element.

Secondly, some supplier links which may give some good insight to
members who may be involved in specifying the same.
