Detailed Product Description

ASTM A209 / ASME SA209 T1A Low Alloy Steel Seamless U Bend Heat Exchanger Tube

ASME SA209 T1A is a material specification for seamless carbon steel tubes primarily used in boiler and superheater applications. This alloy provides good strength at elevated temperatures and moderate resistance to oxidation and creep, making it suitable for high-temperature and high-pressure environments. However, for more aggressive corrosion and higher temperature, other alloys like T22, T91 or Inconel might be used.

Advantages of ASME SA209 T1A Low Alloy Steel Seamless Tubes

Cost-Effective: Compared to higher-alloy steels, SA209 T1A tubes are more cost-effective while still providing good performance for high-temperature and high-pressure applications.
Versatility: They are widely used in a range of industries and applications, thanks to their balance of performance and cost.
Reliability: Being part of the ASME standards, these tubes are designed to meet high safety and reliability standards, ensuring long-term performance in critical systems.

1>. Flattening Test

The flattening test of Specification A999/A999M shall be made on a specimen from one end or both ends of each pipe. Crop ends may be used. If this supplementary requirement is specified, the number of tests per pipe shall also be specified. One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot.

2>. Flaring Test

One flaring test shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot.

3>. Hydrostatic or Nondestructive Electric Test

Each tube shall be subjected to the nondestructive electric test or the hydrostatic test. The type of test to be used shall be at the option of the manufacturer, unless otherwise specified in the purchase order.

4>. Bend Test

For pipe whose diameter exceeds NPS 25 and whose diameter to wall thickness ratio is 7.0 or less shall be subjected to the bend test instead of the flattening test. Other pipe whose diameter equals or exceeds NPS 10 may be given the bend test in place of the flattening test subject to the approval of the purchaser

PT / Penetration Test of U Bend Area

Applications:

Heat Exchanger Tube Bundles: U-bend tubes are often found in shell-and-tube heat exchangers, where they are bent to form part of the tube bundle. These heat exchangers are used in industrial processes like oil refining, power generation, and chemical processing.
Steam Generators: In boiler systems, U-bend tubes are used in the superheater and reheater sections where steam is heated to higher temperatures.
Fired Heaters: U-bend tubes are also commonly used in fired heater systems in petrochemical refineries.
