Main Features for Alloy hot-rolled seamless pipes :

1.High accuracy on tolerance

2.Good Mechanical properties

3.Bear Low Temperature

4. Ductility-brittleness transition temperature is lower than service temperature

5. Strength to meet design requirements

6. Structure stability at service temperature

7.Good weldability and formability; Some special applications also require very low permeability, cold shrinkage and so on.
