Q1: What does SCH 80 mean?
A: SCH 80 stands for “Schedule 80” – a standardized pipe wall thickness used in ANSI/ASME B36.10. It has thicker walls than SCH 40, providing better pressure performance.
Q2: Can SCH 80 pipe be used for steam?
A: Yes. SCH 80 pipes are suitable for high-pressure steam lines, especially when made of A106 Grade B or higher.
Q3: Is SCH 80 carbon steel pipe available in seamless and welded types?
A: Absolutely. We supply both seamless and ERW/LSAW welded SCH 80 pipes.
Q4: Is SCH 80 pipe suitable for threading?
A: Yes. Its thickness makes it ideal for threading and mechanical joining.
