Superheater Tube – Seamless Alloy Steel
For High Temperature Steam Superheating Service
OD 6mm – 204mm | WT 1mm – 18mm | Cold Drawn
Product Overview
Our superheater tube is a seamless alloy steel tube specifically designed for the hottest section of the boiler – where steam temperature is raised above its saturation point to improve thermal efficiency and reduce turbine exhaust moisture .
Manufactured by the cold drawing process from premium Cr-Mo alloy steel, these tubes offer superior high-temperature strength, oxidation resistance, and microstructural stability at temperatures up to 650°C .
Key Features:
High temperature capability – Up to 650°C (1,200°F)
Superior creep strength – Maintains dimensional stability under long-term stress
Excellent oxidation resistance – Chromium content forms protective oxide scale
Microstructural stability – Stable during prolonged high temperature service
100% NDT and hydrostatic tested – Guaranteed integrity
Full traceability – EN 10204 Type 3.1 MTC with heat number
✅ Up to 650°C – High temperature superheater service
✅ Cr-Mo alloy – Excellent creep and oxidation resistance
✅ Seamless construction – No weld seam – critical for superheater reliability
✅ Multiple grades – T11, T22, T91, TP304H, TP347H
✅ Factory direct | Global shipping

Key Requirements for Superheater Tubes
Superheater tubes must possess :
Excellent high-temperature strength – Resist creep deformation under long-term high temperature stress
Good oxidation resistance – Chromium content protects against high-temperature oxidation
Microstructural stability – Stable structure during prolonged service
Creep-rupture strength – Maintain integrity over the design life
Manufacturing Process – Cold Drawing
