How is the hardness of ASTM A179 tube measured?

The hardness of ASTM A179 tube is measured through the Rockwell hardness test. It is a non destructive test that measures the indentation made by an indenter into the surface of the material. The hardness is calculated based on the depth of the indentation. Different scales can be used to measure the hardness of the tube:

• Rockwell B is a simple test and can be used to measure a range of hardness values.
• Rockwell C uses a different indenter and test load.
• Rockwell superficial measures the surface hardness of the material.

What factors determine the selection of a specific manufacturing method for ASTM A179 seamless steel tube?

• The size and shape of the tube- large diameter ASTM A179 seamless steel tube is manufactured using a different method than small diameter tubes.
• The wall thickness of the tube- thick walled ASTM A179 cold drawn seamless tubes are more difficult to manufacture than thin walled tubes.
• The desired properties of the tube like strength, toughness and corrosion resistance, play a crucial role in determining the appropriate manufacturing method.
• Additionally, the cost of the manufacturing method is an important consideration. Some methods may be more cost-effective than others. The selection of the manufacturing method should strike a balance between achieving the desired properties and optimizing production costs.

What types of defects can be detected using ultrasonic testing in ASME SA179 Seamless Tube?

Ultrasonic testing (UT) can be used to detect various defects in ASME SA179 Seamless Tube. This will include internal and external wall thickness variations, internal and external cracks, laminations and inclusions along with weld defects.

How is the surface roughness of ASTM A179 Boiler Tube measured or quantified?

The surface roughness of ASTM A179 Boiler Tubes can be measured using various methods like profilometry. It involves using a profilometer which a precision instrument that measures the surface profile of a material.

It works by tracing a stylus/ laser over the surface and recording the vertical displacement as it moves along the tube. This data is analyzed to determine parameters like average roughness, root mean square roughness or peak to valley height of the ASTM A179 Carbon Steel Seamless Tube.

What is the temperature range of SA179 tubes?

The temperature range of SA179 tubes lies between ambient to 400°C. These SA179 Heat Exchanger Tubes can withstand elevated temps in heat transfer applications like heat exchangers and condensers. However, the specific temperature limits may vary with operating conditions, pressure & exposure duration of the SA 179 Carbon Steel welded Tube.
