ASTM A192 Boiler Tubes are seamless carbon steel tubes used in high-pressure boilers, super heaters, and heat exchangers.

They are designed to withstand high temperatures and pressures and have excellent corrosion resistance. SA 192 Boiler Tubes are widely used in various industries, including power generation, chemical processing & petroleum refining.

A192 Boiler Tubes Flattening Test

One flattening test shall be made on specimens from each end of two tubes selected from each lot or fraction thereof.

A192 Boiler Tubes Flaring Test

One flaring test shall be made on specie- men from each end of two tubes selected from each lot or fraction thereof. These tubes shall be selected apart from those used for the flattening test.

A192 Boiler Tubes Inspection and Test

Chemical Composition Inspection, Mechanical Properties Test(Tensile Strength,Yield Strength, Elongation, Flaring, Flattening, Bending, Hardness, Impact Test), Surface and Dimension Test,No-destructive Test, Hydrostatic Test.

Hydrostatic test pressures of ASTM A192M / ASME SA-192M

Each tube shall be subjected to the hydrostatic pressure test, or instead of this test, a nondestructive test may be used when specified by the purchaser.
