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.
