Kaasupurkausputki

Kaasupurkausputki is a term used in Finnish industry to refer to a pipe that serves as a vent or discharge conduit for gas from a process or piece of equipment. The word is formed from kaas(u) meaning gas, purkaus meaning discharge or release, and putki meaning pipe. In technical Finnish literature it describes piping that conveys gas away from pressure-relief devices, scrubbers, or other process components to a safe discharge point, such as a flare stack, vent header, or atmospheric vent.

Construction and function are oriented toward safety and compatibility with the contained gas. Kaasupurkausputki is typically made from materials resistant to corrosion and the specific chemical or hydrocarbon gas it may carry. It is designed to minimize ignition risk, often installed with proper routing to avoid sources of heat and ignition, and may incorporate features such as flame arrestors, vent heads, drainage arrangements, or minor expansion sections. The piping is usually arranged to be vertical or gently sloped to promote drainage of condensates and to prevent accumulation of liquids.

Applications and contexts of use include oil and gas facilities, chemical plants, waste-water treatment plants, and other industrial installations where gases must be safely vented from equipment during normal operation, fault conditions, or maintenance. The concept may be described in Finnish standards and engineering documents and is closely related to other venting components such as purge lines, relief valves, and flare systems. Standards and regulations governing kaasupurkausputki address safety, environmental impact, and explosion protection, consistent with national and international requirements for gas-handling systems.
