Product Description

Plant Boiler Support Steel Structure, Q355B High-Temperature Heavy-Duty Industrial Steelwork

 

Main Features

A Q355B structural steel support system for power plant boilers, turbines and auxiliary equipment, designed for high-temperature, fatigue-loaded and heavy-duty service.

  • Q355B structural steel main frame, designed for high-temperature service zones

  • Heavy load capacity for boiler, turbine, HRSG and auxiliary equipment

  • Thermal expansion compensation to prevent stress concentration

  • Fatigue-resistant design for cyclic temperature and pressure loading

  • Full platforms, walkways, stair towers and pipe supports

  • High-rate welding with UT/MT/RT NDT inspection

  • Modular prefabrication to shorten on-site construction cycle

  • Designed to GB 50017 / GB 50229, EN 1993 and ASME/IEC requirements

  • Corrosion protection: Sa2.5 + epoxy coating for plant environments

  • Designed and detailed for client's process loads and equipment layout
