Medium Pressure Boiler Tube – Seamless Carbon Steel
For Industrial Boilers & Cogeneration Systems
OD 6mm – 204mm | WT 1mm – 18mm | Cold Drawn
Product Overview
Our medium pressure boiler tube is a seamless carbon steel tube designed for service where working pressures range from 2.5 MPa to 9.8 MPa and operating temperatures are below 450°C . Manufactured by the cold drawing process, these tubes are widely used in medium industrial boilers, cogeneration systems, and small power station boilers.
Key Features:
Medium pressure rating – Working pressure 2.5-9.8 MPa
Moderate temperature – Operating temperature
Higher strength than low pressure – Suitable for more demanding service
Good weldability – Low carbon content
100% hydrostatic tested – Guaranteed integrity
Full traceability – EN 10204 Type 3.1 MTC with heat number
✅ Working pressure 2.5-9.8 MPa – Designed for medium pressure service
✅ Moderate temperature – Up to 450°C
✅ Higher strength – Thicker walls for higher pressure
✅ Multiple standards – ASTM A210, GB/T 3087, EN 10216-2
✅ Factory direct | Global shipping
