Flare Lines or Chimneys

Flare lines, commonly referred to as chimneys, are specialized venting systems used in air conditioning, refrigeration, and heating systems, as well as in industrial environments. Their primary purpose is to safely discharge flammable gases—such as refrigerants—and other combustion byproducts into the atmosphere. These systems are critical in facilities with manufacturing or thermal processes, where the controlled removal of hazardous or combustible gases is essential for operational safety and environmental compliance.

Flare lines serve as conduits that transport these gases from their point of origin—such as production plants, furnaces, or boilers—to the atmosphere, often following a treatment process to ensure emissions meet regulatory standards. Due to the complexity and high-risk nature of these applications, flare lines are typically classified as custom-engineered ductwork, where precise pre-design and engineering are vital to ensuring optimal performance, safety, and compliance.
