Manufacture:
Tubes are made by the seamless process.
Heat treatment:
As a final treatment, tubes shall be reheated to a temperature of 1200℉(650℃) or higher and cooled (as appropriate for the grade) to meet the requirements of this specification.
The martensitic grade UNS S41500 shall be reheated to a temperature of 950℉ (510℃) or higher and cooled as appropriate to meet the requirements of this specification.
Surface Condition:
The finished tubes are free of scale., slight amount of oxidation is not considered as scale.
Test and Inspection:
Mechanical Test
- Tension Test
- Flaring Test
