Pioneering ductwork for ambitious chemicals businesses

With an ever-changing body of rules and regulations, biotechnology, chemical and pharmaceutical facilities must anticipate regulatory changes at any time. A growing number of chemical businesses are focusing on facility exhaust systems to boost and improve their current health, safety, and processes, lending themselves to positive impact and change in the workplace.

Problems facing chemical businesses

Without corrosion-resistant solutions in place, chemical businesses have the potential to unintendedly host fire and explosions. Of course, this makes onsite facilities extremely hazardous – with the use of solvents, dust and flammable liquids often being the culprit. Contamination is also a possibility without a solution in place – affecting production, storage, and cleanroom areas.

Our reliable corrosion-resistant solution has helped many chemical businesses stay safe and fully functional.

Design Considerations

Systems and ductwork should be designed to ANSI/AIHA Z9.2-2001 standards and maintain negative pressure within all portions of the ductwork inside the building when the system is in operation.

Exhaust system ductwork should meet the requirements Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA, 1985) standards.

Exhaust ductwork should be fire and corrosion resistant and selected based on its resistance to the primary corrosive element.

Exhaust system materials should be non-combustible if there is perchloric acid or similar oxidizing agents that pose a fire or explosion hazard are present.

Exhaust ductwork joints should be sealed to protect against a chemical attack.


We often recommend welded stainless steel type 316L, but it may not be appropriate for all chemicals and corrosives. Stainless steel is a risky specification if there is hydrochloric acid or nitric acid vapour present.

Galvanized steel coated inside and out with a 4 mL thick coating of polyvinyl chloride, or a corrosion-resistant epoxy coating, may be an acceptable material for fume exhaust ductwork.

Can I compliment you and your guys for an excellent standard of work, it puts an existing system manufactured by others to shame. Thank you also for your efficiency in delivering as promised, I know where to go for any future requirements
