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

T22 2.25 1.0 1,125°F (605°C) High temperature superheater
T91 9.0 1.0 1,200°F (650°C) High temperature superheater – most popular
T92 9.0 0.5 1,200°F (650°C) Ultra-supercritical superheater

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
