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.
