Another standard for heat transfer applications, providing reliable performance in boiler and heat exchanger systems.
For more demanding heat transfer environments requiring enhanced material properties and corrosion resistance.
High-quality steel billets are carefully selected based on required chemical composition and mechanical properties.
A solid round billet is heated and pierced to create a hollow shell, typically using a rotary piercing mill.
The hollow shell is rolled (hot or cold) or drawn through dies to achieve desired outer diameter, wall thickness, and length.
Pipes undergo various heat treatments such as normalizing, annealing, or quenching and tempering to achieve specific properties.
Including straightening, cutting to precise lengths, and end finishing such as beveling or threading.
Rigorous inspection and testing including visual inspection, dimensional checks, non-destructive testing, and mechanical property tests.
