FAQs
What is the use of ASTM A192 tubes?
Typically, ASTM A192 Tubes are used mainly for high-pressure boiler applications. This is specifically required for industries where steam generation and heat transfer are critical. Hence they are designed with ‘Precision’ to tolerate high temperature, high pressure, and corrosive environments
What is the difference between ASTM A192 and ASME SA192?
There are no major differences between ASTM A192 and ASME SA192. Since they refer to the same specification. The only difference is in the way they are used and certified.
Which sizes and wall thickness are available under ASTM A192?
Usually, the sizes and wall thickness that are under ASTM A192 Tubes are given below:
- Outside Diameter (OD): 6.35 mm to 165.10 mm
- Wall Thickness (WT): 1.2 mm to 12 mm
- Length: Up to 24 meters
