1.
ISO certification is well-known but what exactly is PED?
The Pressure Equipment
Directive (PED) was adopted in Europe in 1997, and required from May 2002
throughout the European Union. Its purpose is to standardize the regulations
regarding the design, manufacture, testing and assessment of pressure equipment
including nitrogen gas springs and systems. All gas springs must be judged to be
safe, and designed and manufactured according to sound engineering practices.
In addition, gas springs above a certain force must meet additional safety
requirements.
The PED standards are among the most demanding manufacturing and quality requirements.
The Hyson manufacturing facility has been certified to manufacture manifold systems, as well as self-contained gas springs including the Super Tanker®, T2 and T3 series of gas springs, to meet PED. In addition, the design of the Hyson Products manifold systems and gas springs has been approved to meet the PED standards.
In receiving these certifications, Hyson
Products continues to strengthen its position of quality leadership in
the production of nitrogen gas springs and manifold systems.

What is the difference between self-contained gas springs, a
hosed system, a baseplate system, a hose and tank system, and
a manifold system?
Self-contained
gas springs
- Each
spring operates independently of one another.
- The
springs can be ordered pre-charged or individually adjusted in
the field.
- Require
the least initial investment.
- The
springs are simply dropped into a spring pocket, bolted down,
or flange mounted.
- Force
increase from initial to full stroke ranging from 30% to 71%.
Hosed
system
- The
valve is removed from the charge port of each spring and the
springs are connected with hoses out to a control panel.
- The
entire system is charged from a central control panel.
- Uniform
pressure throughout the entire system.
- The
pressure can be easily monitored and adjusted.
- The
pressure rise can be customized by the addition of a compression
tank.
Baseplate
system
- Is
a hosed system pre-mounted to a steel plate.
- The
completed system is assembled and pressure tested at the factory.
- The
system can be easily mounted in the tool.
Manifold
system
- Consists
of nitrogen gas cylinders threaded into a metal plate.
- Volume
drilling throughout the plate connects all cylinders to provide
uniform pressure throughout the system.
- The
pressure can be easily monitored and adjusted from the control
panel.
- Pressure
rise from initial to full stroke can be engineered to meet application
requirements (typically 10%-20%).
Hose
and tank system
- Used
when die space is limited.
- Consists
of base mounted nitrogen gas cylinders and an accumulator tank.
- Accumulator
tank can be mounted remotely.
- The
pressure can be easily monitored and adjusted from the control
panel.
- Pressure
rise from initial to full stroke can be engineered to meet application
requirements.
3.
How do gas springs work?
-
- Gas
springs are charged with nitrogen gas to a high pressure and
the gas is sealed inside the spring. The gas pressure acts on
the piston of the spring and provides a resistant force. Using
the equation Charge Pressure = Force/ Area of the piston, the
larger the piston diameter and the greater the charge pressure,
the higher the spring force. When the springs are compressed,
the movement of the piston displaces gas volume resulting in
increased spring force.
4.
I have never used nitrogen gas springs before. Do I have to purchase
additional components in order to install and run nitrogen gas
springs?
Self-contained
gas springs (Tanker® XP and T2) require no additional
accessories if ordered pre-charged from the factory. Nitro-Dyne®
XP Manifold Systems, Tanker XP or T2 Hosed Systems and
Hose & Tank Systems require a high-pressure nitrogen bottle
and a NCA-2600 charging assembly (includes regulator).
5.
Should I use self-contained gas springs, hosed system or manifold
cylinders for my application?
Tanker®
XP & T2® self contained gas springs offer easier
initial installation. However, when it is important to be able
to adjust the pressure in all springs simultaneously a hosed
system should be considered. When a low pressure rise is desired,
a hose and tank system or Nitro-Dyne® XP manifold system
should be considered.
6.
I am currently using another brand of gas springs; can you retrofit
to their existing dimensions?
Hyson
Products T2 self-contained gas springs and Nitro-Dyne XP
gas cylinders are dimensionally equivalent to other gas spring
brands. Contact Hyson Products' Customer Service for cross-over
information.
7.
Why are gas springs preferred over mechanical coil springs?
- Gas
springs provide full load on contact. There is no need to pre-load.
- Gas
springs provide greater tonnage per diameter than coil springs;
therefore one gas spring can replace several coil springs.
- Gas
spring output force can be easily adjusted. At a given deflection,
coil springs cannot be adjusted. To increase or decrease force,
an alternative duty group or spring size must be substituted.
8.
What is the maximum working stroke of the springs?
With
Hyson Products' springs and manifold cylinders, you can use 100%
of the maximum stroke lengths.
9.
What is the maximum charge pressure?
See
the following table for maximum charge pressures.
10.
What nitrogen charging assembly is required to transfer nitrogen
from a commercial bottle of nitrogen gas to the gas spring or
system?
See
the following table for nitrogen charging assemblies.
11.
What service gauge assembly connects to the nitrogen charging
assembly and is required to charge the spring?
See
the following table for service gauge assemblies.
12.
What quick disconnect charge fitting is needed?
See
the following table for quick disconnect charge fittings.

These gas springs are no longer manufactured but Hyson Products does support them with service and repair kits.
Note:
The charge fitting is only required when charging self-contained
springs. It is not needed for a hosed or baseplate system.
Note:
The maximum charge pressure for all manifold systems is marked
on the specification tag located on the manifold plate.
13. What is the maximum operating temperature?
The
maximum operating temperature of standard gas springs and manifold
systems is 80°C/ 176°F. However, high temperature gas
springs and manifold systems are available. Contact Hyson Products
for more information.
14.
What is the difference between Tanker and T2 gas springs?
The Tanker Series, whether the original Tanker, the Tanker XP, Super Tanker, or the new TankerT and TankerS,
features a bore seal design, meaning it seals on the bore of the cylinder tube not on the rod.
This is especially beneficial in extreme conditions. Since the sealing surface is never exposed to
the outside environment, the Tanker Series performs exceptionally in demanding applications.
It also features dynamic lubrication so the seals and the cylinder walls stay lubricated for
reduced heat and friction, and long service life.
The T2 gas springs meet the automotive standard. They are available in a variety of models and stroke lengths.
All models, except the T2SC series, are rod seal design, meaning they seal on the piston rod.
The cartridge style guide allows for quick rebuilds.
15.
How do I calculate the charge pressure needed to generate the
desired contact force?
Using
the equation P=F/A where A is the effective area (listed below
per model), and F is the desired contact force per spring, you
can calculate the charge pressure, P, required. For example:
If you want to generate a contact force of 1200 lbs. using one
T2-750, the charge pressure would be 1200 lbs ÷ 0.761
in˛ = 1577 psi.
