Commonly Used Explosion-Proof Products
Industrial fires and explosions cost companies
in off-shore exploration, industrial and manufacturing industries and food and
beverage industries billions of dollars every year, not to mention the loss of
life that can’t be described in monetary means. According to the National Fire
Protection Association (NFPA), an average of 37,000 fires occur at industrial
and manufacturing industries per year. These incidents also resulted in 18
civilian deaths, 279 injuries and $1 billion direct property damage.
These disasters happen for different reasons
such as combustible dust; hot work; flammable liquids and gasses; equipment and
machinery; and electrical hazards. Because of these, metal companies developed
and continuously innovate a complete line of products that will help prevent explosion.
Commonly used explosion-proof products
A wide array of explosion-proof products such
as instrument enclosure, junction boxes, stopping plugs, transmitter,
indication alarm units, sunshades and valves and manifolds can be purchased
from different junction box suppliers in Singapore.
These products are economically priced and ISO-certified. Out of these
products, the commonly used explosion-proof products are thermocouple heads,
terminal boxes, condensate pots and instrument enclosures.
· Thermocouple heads
Explosion-proof thermocouple heads come in
aluminum and stainless-steel heads. The aluminum heads are designed
specifically for explosion-proof applications and constructed out of die-cast
copper-free aluminum to withstand applications where aggressive atmospheres
prevails. The housing for these thermocouple heads accommodates a terminal
block that can be mounted using M4 screws. Meanwhile, stainless-steel heads are
designed specifically for explosion-proof applications and constructed out of
SS316 to withstand applications where aggressive atmospheres prevails. Further,
there are also stainless-steel heads designed for larger devices. Thermocouple
heads are used in cases where there is a junction of two dissimilar metals that
could cause difference in voltage output proportion.
· Terminal boxes
Explosion proof junction
box are available in Singapore with a solid choice of solid or tempered glass cover in
either copper-free aluminum or SS316. Most often than not, these terminal boxes
can accommodate up to 10 phoenix terminals. These terminal boxes offer
protection from explosive hazards and ignitions, dust, harsh weather and rough
treatment.
· Condensate Pot
Condensate pots have been tested to pressure
above 6500psi and can be safely used up to pressures of 6000psi at elevated
temperatures. These products are available in both carbon steel and SS316. The
primary use of condensate pots is to increase the accuracy flow measurement in
steam pipelines.
· Instrument enclosures
Instrument enclosures come in single
compartment and dual compartment. Single-compartment instrument enclosures and dual-compartment
instrument enclosures are designed to accommodate circuit boards and devices that
are specifically designed for explosion-proof applications. These enclosures accommodate
temperature, pressure, level and flow transmitters, meters, indicators,
analyzers, integrators and many other instruments.
A number of other explosion-proof products can
be identified in the Internet each with different uses and purpose. Most of
these products are ISO-certified and produced by companies providing solutions
for off-shore exploration, industrial and manufacturing industries and food and
beverage industries. Details and other specifications can also be found in the
company’s website. Most of these companies offering such products offers
custom-made products that fits their client’s needs.
