Liquefied petroleum gas is a high quality fuel that comes in two different
Versions, as propane (C3H8) and butane (C4H10), or
is available in the form of a mixture of the two. The keeping

In the open air, propane is essentially used - always
using a pressure reducing valve or hose rupture valve,
while for industrial purposes at room temperature too
Butane can be applied.
In principle, two things are important when using liquefied petroleum gas

Liquid gas does not produce any harmful side effects (gases).
Only carbon dioxide and water vapor. The gas contaminated

corrosive, does not corrode metals and is non-toxic.
In other words, LPG is an environmentally friendly product.

Words the energy content is very high. Liquefied petroleum gas can also be used
in special containers (gas bottles) for a longer period of time
stored without the gas escaping.
Avoid storing gas cylinders in warm areas.
The best and safest storage temperature for gas cylinders is below
Zero degrees Celsius. Also make sure there is good ventilation.
In principle, liquid gas can also be stored for longer periods of time
without noticeably affecting the quality. At
However, all add-on parts (regulator,
Hose rupture protection devices) must be removed from the bottle. Around
To drain a functioning system, first close it
the gas valve of the bottle, and then release the remaining gas
from all additions. This is when the system is started up again
the system avoids leakage of residual gas.
The highest possible flame temperature when using
Liquid gas is 1925ºC (theoretical). In practice this will be
Temperature not reached when heating up an object. The
Flame temperature depends on the size of the object
Type of heat supply (cyclone technology), the size of the burner
and from the time how long the corresponding object is heated.
Therefore, depending on what work is to be done, it is
important to adapt the burner accordingly.
For the gasification of propane a heat of steam formation of approx
100 kilogram calories are required per kilogram of gas. This warmth
is released from the surrounding air through the wall of the gas container
and the liquid propane was added to the container. At large

depends, and a connected LPG apparatus thus receives
not the full burning effect. When using large burners with high gas consumption
you therefore need large bottles with enough available
Gas. If these are not available, you can
several small gas bottles can be connected to one another.
The small propane bottle we sell is type approved (EN 12807) and may be operated without a protective cap. After the initial filling, the smallest bottle is to be transported as class 2 .1, 2F hazardous goods according to the Hazardous Goods Ordinance on the road for short, GGVS / ADR and does not require any transport documents. In principle, the following applies to safe transport: Suitable transport equipment (e.g. our wooden case 720103) must be used. The gas bottles must be secured against slipping on the loading area. Only approved small propane bottles may be transported within the test period. Only properly labeled small propane bottles may be used. Damaged test labels must be replaced. Ensure that there is adequate ventilation. Smoking and open sources of ignition are prohibited in the cargo area.
The trade associations regulate the handling of liquid gas. The corresponding regulation is: BGV D34 - Use of liquefied gas and can be read in or downloaded from the employers' liability insurance association's website.
In Germany, liquid gas may only be fed into the propane hose with a so-called pressure control device. If you work commercially, the use of pressure regulators on work equipment is mandatory.
This depends heavily on the use of the respective burner. Basically, however: soldering torches, shrink burners are generally operated with 2 bar working pressure, heating or welding torches are usually operated with 4 bar working pressure.
That also strongly depends on the burner used. Burners with self-ignition (piezo ignition) usually only work with the working pressure provided for them, as the ignition is matched to the respective pressure. If the pressure is not right here - the burner will not ignite.
Hose rupture safeguards are used above ground level and shut off the gas supply to the pressure regulator if the hose is damaged. It must be activated by pressing a button before starting work. This activation brings a spring-cone system into equilibrium, which automatically blocks the gas supply in the event of a hose rupture. The hose rupture protection must be selected depending on the equipment used (2 bar, 4 bar). It is easy to use with pressure regulators with integrated hose rupture protection. Here the pressure regulator and hose rupture protection are optimally matched to one another.
Hose rupture protection devices are mandatory in Germany when using gas cylinders over 1 liter (425 grams).
Basically, the date of manufacture is printed on every propane hose. This can be used to track when a propane hose was produced and thus determine its age. Legislators do not have a best-before date or regulation when a propane hose is to be replaced. Here, however, one can be viewed as a thumb regulator. If a propane hose becomes brittle and gets fine cracks, it should be replaced with a new hose immediately.
No! Disposable gas cartridges have no best-before date. If stored properly, they will still function perfectly even after years.
Propane is heavier than air. There is therefore a risk of gas collecting in pits, tanks, holes, windowless basements, etc. All work that must be carried out in such an environment is referred to as work below ground level.
In such an environment, the use of gas leakage safeguards is necessary. Depending on the work to be carried out, leak gas safeguards with special double-walled hoses must also be used here. For more information, read our information brochure “Working below ground level - but doing it right!
Leak gas safety devices detect even the smallest gas leaks and then immediately switch off the gas supply to the gas cylinder. Pressure regulators only react when there is a certain amount of gas flowing out. This makes them unsuitable for use below ground level.
Soft soldering means working in which the melting temperature of the filler metal used (soft solder) is below 450 degrees Celius.
Yes! A distinction is made between indirect soft soldering, also known as piston soldering. Here the heat is transferred by means of a piece of copper. Another method is direct soft soldering. The heat is transferred directly to the workpiece by means of an open flame.
Indirect soft soldering is used particularly in the roofing area. Gutters, wall coverings, etc. are indirectly soft-soldered.
A large area of application is the soft soldering of copper pipes in the sanitary, heating and air conditioning sectors.
Brazing is understood to mean working in which the melting temperature of the filler metal used (hard solder) is above 450 degrees Celsius.
No. We only sell empty 425 gr. Small propane bottles. In Germany, however, you can easily fill this yourself using a suitable refilling nozzle (see item no. 770327 or 757007). You will find filling instructions on the smallest bottle.
In principle, all refillable gas bottles have a date of manufacture, which is stamped on the base of the gas bottle. From this date, the gas cylinder can be used commercially for 10 years. After 10 years, a new TÜV test must be carried out on the gas cylinder.
No. We only sell product-related gas bottles for refilling. Commercially available 5, 11 or 33kg gas bottles can be obtained from your local gas dealer or, in the meantime, from almost every hardware store.
