ASME SA179 U Bend Seamless Cold Drawn Carbon Steel Tube For Tubular Heat Exchangers

ASME SA179 Seamless cold drawn carbon steel boiler and superheater tubing

YH specialises in offering high quality Carbon Steel SA179 Tubes, known for its excellent tensile and yield strengths.The unparalleled properties of SA179 grade include excellent resistance to corrosion, oxidation, pitting, acids and crevice corrosion, ensuring outstanding performance in a wide range of applications.

We will attach great importance on ovality this article.

ASTM A179 Tube Sizes

Ovality

Ovality equal to Maximum diameter cut minumum diameter and divide nominal diameter, please check below formul,

Ovality (%) = (Dmax - Dmin) / Dnominal x 100

• Dmax: Maximum diameter of the pipe

• Dmin: Minimum diameter of the pipe

• Dnominal: Nominal diameter of the pipe

Noted, If client requires a "ball-passing test", factory should prepare the ball. 

Contact us, and we will provide the yuhong documents for u tube bending inspection record for your reference.

Heat Exchanger

Heat exchanger tube using tooling for cold bending, cold bending forming process to meet the Sufficient size tolerance requirements. After passing the test, the bending section and straight section of at least 150 mm range(150mm+150mm) of stress relief heat treatment according to the standard. After heat treatment, and then one by one hydraulic test.

Application

For manufacture wall panel, economizer, reheater, superheater and steam pipeline of boilers.
