EXERCISE 53 : Setting up OXY-Acetylene plant

Objectives

At the end of this exercise you shall be able to
• set up the oxy-acetylene plant.

Objectives

• Move oxygen and acetylene cylinders with the caps from the store to the gas welding area. An oxygen cylinder
is identified by the black colour painted on it. An acetylene cylinder is identified by the maroon colour painted
on it. Also the oxygen cylinder will be taller than an acetylene cylinder and the diameter of oxygen cylinder will
be less than the diameter of an acetylene cylinder.

Fig 1

• Ensure cylinders are kept separately from the empty cylinders.
• Position the gas cylinders in a trolley and secure them with a chain.
• Always keep the cylinders upright/vertically in the cylinder stand/on the floor (Fig 2)

• While moving, the gas cylinders should be kept slightly inclined to the vertical position and the protector cap
used to avoid damage to the cylinder valves. (Fig 3)
• Do not roll the cylinders horizontally on the ground.

• Remove the cylinder caps. Crack the gas cylinder valves by qucikly opening and closing them using the
cylinder key. Fig 4
• Dirt dust particles from the cylinder valve sockets are cleaned by cracking the cylinder valve. This will avoid
leakage of gas due to improper seating of the cylinder valve and also to prevent the dust particles from
entering into the regulators which may cause damage to the regulators.
• Always stand opposite to the valve outlet while cracking the cylinders. (Fig 5)
