There are multiple tube bending services to be found online on various websites. The most recommended websites are 'Tube-Bending-Service' and 'Barnshaws'.

Neon in German is - Neon (!) Neon tube is Neonröhre
Neon tubes come in a variety of lengths and, therefore, weights.

Cutting a glass tube is a physical change because the cut glass tube still has the same chemical composition as the uncut tube. Nothing has changed except the physical appearance of the glass tube.
Because it will provides maximum dflection in Only vertical direction and no any other bending of tube due to pressure occurs.instead if cross section is circular then along with vertical defletion or bending of tube there is also bending along horizaotal direction,which leads to error.so it has oval shape............got it
Neon gas has a break-down voltage of about 70 volts. When the gas (in a neon voltage regulator tube) breaks down, the gas glows red. If more voltage is applied (within sensible limits) the voltage drop across the neon VR tube will still be 70 volts. This action by itself could result in a large current flowing in the gas tube and possibly to destroy it, so a resistor is placed in series with the neon VR tube to limit the current. And this is better for the neon tube as well. THUS a neon voltage regulator tube forms a reference voltage which can be used, with clever circuitry, to regulate any voltage. Other gas mixtures are used for other voltages. There are solid-state devices with similar properties.
tube light us formed by sum inerts gasses like neon because they do not react with electron and the friction between electron and neon produced light.
It could be several issues that affect the sign... It could be a burned gto wire going from the transformer to the tube, or it could be a burnt up transformer, or a broken neon tube. Typically, the neon tube is removed from the sign. If it is a red gas tube, it can be repaired by bending up the missing section, and welding it with fire back together. Then it must be pumped (bombarded) If the tube is green, blue, white, yellow, or any other color that uses Mercury to aid its light output when originally lit, then great care must be taken. Vaporizing mercury is very toxic to the health of neon workers and this type of tube needs to be made new, with the old tube being properly disposed. I have fixed a few mercury tubes, but I do not advise it to anyone. If the state finds out where mercury tubes are being repaired, they can come close you down if they find loose mercury or contaminated premises, or worse... do something that affects the title to your property!!
When you put neon gas in a tube and electrically charge it, this creates a neon sign.
