Metal cutting
MIDDLE EAST INDUSTRIAL GASES COMPANY4
Traditionally cutting of metal has been done by using Oxy-Acetylene mixture.
Acetylene is expensive and more importantly notenvironment friendly to produce and dangerous to use
Middle East Gas Company has studied the needs offabrication industries and came up with the idealsubstitute for acetylene.
The new age cutting gas has been a great success inOman, Malaysia ,UAE ,Kuwait ,Nigeria & Qatar . Excitedwith the success,NGC in association with MEIGC intends totake the huge advantages of NC+ in the Kingdom of SaudiArabia.
FAQ : Oxy- Fuel
MIDDLE EAST INDUSTRIAL GASES COMPANY5
The Basics of Oxy-Fuel Cutting
Q. What is Oxy-Fuel Cutting?
A. Oxy-fuel cutting is a chemical reaction between pure oxygen andsteel to form iron oxide. It can be described as rapid, controlledrusting.
Q. How does it work?
A. Preheat flames are used to raise the surface or edge of the steel to
approximately 1800°F (bright red color). Pure oxygen is thendirected
toward the heated area in a fine, high pressure stream. As thesteel is
oxidized and blown away to form a cavity, the preheat and oxygenstream are moved at constant speed to form a continuous cut.

Acetylene Facts
MIDDLE EAST INDUSTRIAL GASES COMPANY7
Highly unstable Gas due to the triple bond in its molecularstructure.
Un-dissolved Acetylene Gas Can Explode even by a minorshock.
Can explode if Stored Without Filter Pad. Can explode without fire. Fast Decomposition. 1 Gm C2H2 = 3.5 Gms of TNT. Extremely flammable and explosive. Very wide flammability limit, Easy to ignite and burns at
faster rate.
Hazards associated with Acetylene
MIDDLE EAST INDUSTRIAL GASES COMPANY8
Acetylene has a triple bond in it’s chemical structure
This triple bond makes Acetylene inherently a very unstablegas.
Acetylene can’t exist in un-dissolved state even for a while ,hence can not be piped
Because of unstable nature it’s always kept under dissolvedstate in Acetone inside the porous mass.
It’s very sensitive to any kind of shock and shock can triggerthe decomposition of Acetylene which might lead todangerous situations and loss of property and life.
Great care is to be taken while filling, transporting and usageof this Acetylene.
The sludge formed during production of Acetylene poseshigh environmental hazards and very difficult to dispose.
Advantages of NC+ : Safety
MIDDLE EAST INDUSTRIAL GASES COMPANY9
Very stable, safe and environment friendly gas
Has ten times lower explosive limits than acetylene henceten times safer than Acetylene.
Non toxic, non injurious and has no torch back fire ordangerous by product.
Less luminous flame hence not harmful to eye sight
Easily detectable in case of leakage due to its uniquepungent smell.
The cylinder pressure of NC+ is 5-6 bars where as thecylinder pressure in acetylene is 17-18 bars
Reduced hazard point

Product pressure inside cylinder. 7-8kg/cm2. 17-18kg/cm2.
Cylinder Design Collar and foot-ring, which give ease for handling the cylinder
compared to DA cylinder.
No collar so it is difficult in handling.

1 nc+ cylinder( 44kg/100 lbs)=Acetylene cylinder. Storage is
reduce by 12-14times, as a result potential hazard zone reduce
by 12 times as compared to Acetylene.
Similarly for 22kg/50lbs storage reduce by 6 times and hazard
zone reduce by 6 times.
High
12 times more potential hazard zone as compared to 44kg nc+
cylinder.
Similarly 6 times more potential hazard zone as compared to
22kg nc+ cylinder.
I gram of Acetylene is equivalent of 3.5 grams of TNT
Piping nc+ transportation thru’ pipeline is safe.
nc+ is stable Gas so, it is safe to use thru’ piping as well as
cylinder.
Transportation thru’ pipeline is not advisable, manufacturers
suggest keeping the Acetylene in a Dissolved state and advise to
use only thru’ cylinder.
Advantages of NC+: Convenience
MIDDLE EAST INDUSTRIAL GASES COMPANY11
Higher penetration
Reduces cylinder inventory by Five to six times comparedto acetylene hence less handling
Very clean cut surface
Low slag formation and almost nil backfire tendency
NC+ Cylinder is easier to handle due to its better designand less weight than acetylene.
NC+ can be piped to multiple application point from acentral storage location.
NC+ can easily cut metal of 12 inch and thicker with betterfinish
No sooty flame

State NC+ is stored in free state.
NC+ is stable gas and can be filled in a
free state inside cylinder.
Acetylene is stored in a
Dissolved state.
Due to shock sensitivity the
acetylene in dissolved in
acetone to avoid the
disintegration of the
hydrocarbon bond during
cylinder handling and sudden
shock.
Advantages of NC+: Economic
MIDDLE EAST INDUSTRIAL GASES COMPANY13
Less oxygen consumption compared to acetylene
Less overall cost per unit length of cutting surface
Flame temperature with oxygen 3000 deg. C
Very low switching over cost from acetylene
Higher nozzle life hence lower recurring cost
Superior cutting at an incredibly low cost (better cuttingspeed, narrow kerfs formation and surface finish)
Very low capital investment compared to Acetylenebusiness
