ASME SA213 T9 U BEND TUBE ALLOY STEEL TUBE FOR SUPER HEATER
概述
The ASME SA213 T9 Tube is commonly used in modern power devices to ensure their efficient and safe long-term operation. It is specifically designed for heating water in closed loop piping systems for general facility and service water heating. These systems can operate at low temperatures below 200°C or at medium temperatures between 200 and 250°C. The SA213 T9 Boiler Tube is made from heat-resistant carbon and low alloy steel, allowing it to withstand various pressures and temperatures. It is commonly used in boilers, super heaters, economizers, heat exchangers, and other energy-related equipment. The T9 boiler tubes are manufactured using both hot rolled and cold drawn techniques, with both welded and seamless options available. The size and grade of the tubes depend on the specific requirements of the boiler manufacturer, including the type of fuel, temperatures, pressures, and steam quantity needed.
