Hoses larger than 2”
Whenever possible, high pressure hoses should
always be connected directly to Danfoss pro-
vided adapters and check valves. Elbows and
distance pipes should be avoided to prevent
excessive side loads.
Danfoss 3” HP hoses are nylon reinforced; when
using hoses that are not steel reinforced the
connected items must be grounded to avoid
electrical stray currents.
Always provide some slack on straight hose in-
stallations. This compensates for hose length
variations with differences in internal fluid
pressures. A small angle will reduce the forces
from the hose and allow the hose to bend
when pressurized.
Flexing a metal hose in two separate planes of
movement will torque the hose assembly.
Always install the metal hose assembly so
that flexing occurs in one plan only and this
is the same plane in which bending occurs. If
multiple planes of motion are required use a
dog leg assembly.
The installation should allow a straight
distance S before bending the hose. Not
doing so may compromise the hose
reinforcement and cause hose failure.
Max. bending angle and distance S can be
found in table 1 on page 6.
Hoses should not be twisted and should
only have one bend.
