Portable Pipe Constant spring Hangers for various pipe installation
Product description
Constant force constant crane is designed according to the
principle of torque equalization.Under the allowable load
displacement, load torque and spring torque always adhere to the
balance.For the pipe and equipment supported by the constant crane,
it can provide a constant supporting force when the displacement
occurs, so it will not bring additional stress to the pipe
equipment.
The constant crane is generally used in the center where the
displacement stress is reduced, such as the suspension part of the
boiler body of the power station, steam, water, smoke, wind pipe
and extinguisher of the power plant, and the center where such
supports are required in the petroleum and chemical industries.When
the thermal displacement of a lifting point in the pipeline system
is greater than 12mm, it is appropriate to choose a constant crane
to support, in order to prevent the pipeline system from generating
risky bending stress and adverse stress transfer.

When locked, 2 times maximum working load is acceptable.
Structure composition and working principle
Our company mainly operates and consumes the spring type constant
force support and hanger, and can also provide the main and
auxiliary spring type or other ways of constant force support and
hanger according to the user's request.The spring constant force
support hanger is designed according to the principle of torque
equalization.It relies on the exquisite geometric design, so that
load torque and spring torque in the work process has been
balanced, in order to adhere to the constant support force, can
eliminate or reduce the additional stress on the pipeline or
equipment.
Main and auxiliary spring type constant force support hanger is
designed according to the principle that the resultant force is
constant under the action of the main spring force and the
auxiliary spring force.
The spring type constant force support hanger is mainly composed of
cylindrical spiral spring and lever mechanism.Because its spring
and component manufacturing technology is simple, mature, the
product performance is stable, the economy is good, has been used
for a long time in the domestic, therefore is the most widely used
type;The performance of the constant force hanger with the
butterfly spring is relatively difficult to control, while the main
and auxiliary spring constant force hanger requires high precision
of the spring, so it is relatively difficult to manufacture, so it
has not been widely used.
The company USES the introduction of ITT Grinnell support hanger
design, manufacturing technology, the introduction of the domestic
production of 58 series of constant force support hanger, with a
variety of ways, selection of bento, excellent performance
characteristics, by domestic and foreign users.
