What are SA192 Double H fin tubes?
SA192 Double H fin tubes are specialized heat exchanger components crafted from seamless carbon steel tubes according to the ASME SA192 standard. The unique design involves incorporating two SA192 bare tubes within each finned tube unit. This configuration, commonly referred to as "H type carbon steel finned tubes," maximizes heat transfer efficiency by combining the thermal conductivity of carbon steel with the enhanced surface area provided by the Double H fin design.
These finned tubes are designed to withstand demanding operating conditions. The design temperature is specified as 200°C, and the design pressure is set at 23 bar (gauge pressure). This indicates that these finned tubes are intended for applications involving high temperatures and pressures, making them suitable for processes such as superheating and high-pressure heat exchange.
The ASME SA192 standard lays out the requirements for seamless carbon steel boiler and superheater tubes used in high-pressure service. The tubes covered by this standard are expected to have minimum wall thickness to withstand the stress and conditions associated with high-pressure environments.
SA192 Double H fin tubes can find applications in industries such as power generation, petrochemicals, refineries, and other high-pressure and high-temperature processes where efficient heat transfer is essential for optimal performance.
