Painepulloa

Painepulloa is a rigid pressure vessel designed to store gases or liquids at pressures higher than ambient. It is typically used to hold compressed gases for industrial, medical, scientific, or consumer applications and is intended to dispense or transfer contents through a valve, regulator, or fitting.

Design and construction commonly feature a cylindrical body with rounded ends, built from materials such as steel, aluminum, or composite fibers. Each painepullo carries markings that indicate its material, service pressure, volume, manufacturing standards, and testing history. Valves, pressure-relief devices, and mounting hardware are integrated to enable safe filling, storage, and use. Because of the internal pressure, proper handling, storage upright positioning, and protection from physical damage are essential.

Common applications include medical oxygen cylinders, industrial gas cylinders (for nitrogen, argon, or CO2), welding and cutting gas cylinders, and consumer carbonation or propellant cartridges. Service pressures vary by gas and cylinder type, ranging from tens to several hundred bar; scuba cylinders, for example, commonly operate around 200 bar, while some specialty cylinders can exceed 300 bar.

Safety and regulation are critical: painepulloa are subject to standards and periodic testing to verify integrity. In many regions these standards cover design, fabrication, inspection, hydrostatic or pneumatic testing, and hydro and chemical compatibility. Improper handling, overfilling, exposure to heat, or corrosion can lead to leaks or catastrophic failure. Regular maintenance, leak checks, and adherence to manufacturer guidelines are essential for safe operation.
