Safety & T
echnical Information
PetroleumTransfer Hose
• Do not use for oil or fuel delivery or transfer service
when submerged in, or on the surface of open
water. Hose damage or failure may result in spillage
and environmental damage. Use hose specifcally
designed for this application.
• Do not immerse in fuel. Te hose cover compound
may not be of sufcient grade to resist attack by
the fuel. Use hose specifcally designed for this
application.
Steam Hose
Water changes to hot water and phases of steam when
subjected to heat and pressure. Te greater the pressure,
the higher the temperature required to achieve and
maintain a steam phase. If steam escapes, dangerous
quantities of heat may be released very suddenly. Refer
to ARPM publication IP-11-1 “Guide for Use, Testing and
Inspection of Steam Hose.”
WARNING! Use ONLY steamhose for steamservice.
Hot water, low pressure steam and high pressure steam
may escape explosively and will scald skin, eyes and
lungs, which may lead to severe bodily injury or death.
• Many steam systems incorporate detergents or rust
inhibitors which may attack steam hose. Prior to
using a steam hose with detergents or rust inhibitors,
refer to the chemical guides in this catalog, or contact
Parker.
• Parker recommends using permanent crimp
couplings when fabricating steam assemblies. Refer
to CrimpSource at www.safehose.com. Couplings
attached with bands or clamps may reduce the
working pressure of the hose assembly to less than the
maximum rated working pressure of the hose. Refer to
the NAHAD Industrial Hose Assembly Guidelines.
• Drain steam hose after each use to reduce the
possibility of hose popcorning while in service.
Techart at theright represents the three formsofwaterwhen
subjected to various combinations of heat and pressure. Te
red line represents the point at which hot water becomes
saturated steam. Te area below the red line is hot water; the
area above the red line is superheated steam.
Welding Hose
Many accidents involving welding hose occur due to
selection of an incorrect hose for the application. Welding
hose must be specially designed and compounded to
handle the media, with rubber compounds able to handle
fuel gas and oxygen. Due to the extreme volatility of gases,
the varying compatibility of gases with the various grades
of hose, and the rough environment of many welding
applications, it is crucial to select the correct welding
hose. Refer to ARPM publications IP-7, “Specifcations
for Rubber Welding Hose” and IP-11-5, “Guide for Use,
Maintenance and Inspection of Welding Hose.” Also refer
to the Compressed Gas Association publications E-1,
“Standard forRubberWeldingHoseandHoseConnections
for Gas Welding, Cutting and Allied Processes” and Safety
Bulletin SB-11 “Use of Rubber Welding Hose.”
WARNING! Welding gases possess volatile
characteristics that may produce fre or explosions
causing property damage, serious bodily injury or
death. Use Grades R and RM ONLY with acetylene fuel
gas; do not use with any other fuel gases.
• Replace all assemblies that show signs of abrading,
abuse, age, damage or fatigue. Do not attempt to re-
couple, repair or splice hose assemblies.
• Fabricate hose assemblies using only crimped-on
ferrules at least one inch long to ensure coverage and
support of the coupling stem inside the hose.
• Couplings attached with bands or clamps may reduce
the working pressure of the hose assembly to less
than the maximum rated working pressure of the
hose. Refer to the NAHAD Industrial Hose Assembly
Guidelines.
