18 KMHCA0711
Abrasion — Scuffng, rubbing or wear of a hose or
braid surface.
Ambient Conditions — The surrounding
environment to which a hose assembly is subjected.
This includes temperature, corrosion and abuse
conditions.
Annular — With reference to the convolution form,
meaning independent corrugations straight and
parallel.
Armor — Flexible interlocked tubing placed over
the entire length or in short lengths at the ends of a
metal hose to protect it from physical damage and to
limit bending.
ASME — American Society of Mechanical
Engineers.
Bend Radius — The centerline radius of a hose in a
bent condition.
Braid — A fexible metal sheath surrounding metal
hose that prevents the hose from elongating under
pressure. Braid is composed of a number of wires
wrapped helically around the hose while at the same
time going over and under each other in a basket
weave fashion.
Compressed — Interlocked hose in its completely
closed state.
Extended — Interlocked hose in its completely open
state.
Fatigue — The process of failure in a metal hose
associated with motion or pressure.
Floppy Interlock — Constructed for maximum
fexibility.
Helical — With reference to the convolution form,
meaning one single convolution generated along
the axis of the tube in a manner similar to a screw
thread.
Interlocked Hose — Formed from profled strip and
would into fexible metal tubing with no subsequent
welding, brazing, or soldering. May be made
pressure tight by winding in strands of packing.
Intermittent Bend radius — The designation for a
radius used for non-continuous operation. Usually in
an elastic radius.
Loose Wound Interlock — Loosely wound
interlocked hose. Will not hold its shape.
Minimum Bend Radius — The smallest radius to
which a hose is permitted to be bent, generally
applicable only to static conditions. Sometimes
referred to as static bend radius.
Natural Lie (Relaxed) — Interlocked hose halfway
between the compressed and extended state.
Offset — A condition wherein the ends of a hose are
displaced laterally with respect to each other with
the ends being in parallel planes. Sometimes referred
to as lateral offset, shear, or parallel offset.
Operating Conditions — The designation of
pressure, temperature, motion media and environ-
ment. Used interchangeably with “application.”
Packing — Material inserted into the windings of
interlocked hose to make it less susceptible to
leaking.
Pressure — The internal hydraulic or pneumatic
force applied to a metal hose.
Rough Bore — Interlocking metal hose that allows
movement of media in either direction. (Unlined)
Smooth Bore — Interlocking metal hose that uses
an additional strip to create a smooth transition of
media in one direction only. (Lined)
Square Cutting — Cutting the end of a metal hose
so that the end will be completely fush with a ftting
for attaching.
Squarelocked Hose —
Flexible metal hose that is
not mechanically locked
together.
Standard Interlock —
Flexible interlocked hose
that offers fexibility, strength
and service life.
Torque — A force that
produces rotation on an interlocked hose.
Vacuum — Negative pressure or suction.
