Listing ID #2033460

General description
in combination with oxygen, acetylene a-40 filling is used for gas cutting and welding.
Features
colourless and slightly lighter than air
it is non-toxic, but has an anesthetic effect if inhaled
acetylene is highly flammable
when mixed with oxygen for welding, the flame temperature will reach 3100º c
benefits
for your safety, the product is delivered in a unitor cylinder complete with barcode and unique cylinder serial number.
We trace and track all cylinders using the unitrak system to give you peace of mind

acetylene mixed with air is explosive within 2.2% to 85% by volume. Avoid releasing acetylene into the air and ensure good ventilation where acetylene cylinders are stored or used.
When acetylene cylinders are transported horizontally and placed vertically again after transport, a period of at least 24 hours before using the cylinders for gas extraction must be obeyed. This to ensure that the acetone inside the cylinder redistributes in a correct way. When cylinders are used too quickly after placing them vertical again the following can happen:
* when opening the top valve, large amounts of acetone can come out. The customer might interpret this as wateroil because acetone feels slippery on the skin. Opening the top valve without a fitted regulator should not be standard practice as this can create a fire hazard.
* when a regulator is fitted with twinhose and torch, the lighted flame will be very unstable due to the presence of acetone droplets in the gas. This is often referred to as “spitting”.
Solution is to let the cylinder rest for at least 24 hours (depending on temperature; colder environment might require longer time).
Tare "a" weight of acetylene cylinders includes cylinder shell, neckring, valve, porous mass and acetone. For acetylene the following is valid:
1 nm3 = 1.095 kg
1 kg = 0.91 nm3
1 bar = 14.5 psi
1 nm3 = 35.3 ft3
1 kg = 2.2 lbs
