उत्पाद वर्णन

Boiler Quality (BQ) plates are specialized steel plates designed to withstand high pressure and extreme temperatures, making them essential for boilers, pressure vessels, and heat exchangers. They are known for their durability, weldability, and resistance to cracking, ensuring safety and efficiency in industrial applications.

 What Are Boiler Quality Plates?

• Definition: High-strength carbon steel plates engineered for use in pressure vessels and boilers where durability under stress is critical2.

• Purpose: To resist high pressure, elevated temperatures, and corrosive environments in industries like petrochemicals, power generation, and refineries.

• Standards: Common grades include ASTM A516 Gr. 60/70 and IS 2002 Gr. 2, which meet international specifications for boiler and pressure vessel steel.

   

  Key Properties

  • High Tensile Strength: Ensures plates can handle extreme pressure without deformation.

  • Excellent Weldability: Allows easy fabrication and joining in boiler construction.

  • Impact Resistance: Maintains toughness even at low temperatures.

  • Corrosion Resistance: Protects against chemical reactions in harsh environments.

  • Longevity: Designed for long service life under demanding conditions.

  Applications

  • Industrial Boilers: Core material for manufacturing boiler shells and components.

  • Pressure Vessels: Used in storage tanks for gases and liquids under pressure.

  • Heat Exchangers: Ensures safe transfer of heat in power plants and refineries.

  • Petrochemical Industry: Handles aggressive chemicals and high-pressure processes.

  • Power Plants: Critical for steam generation and energy production.

   Risks & Considerations

  • Wrong grade selection can lead to structural failure under pressure.

  • Poor welding practices may reduce durability and cause cracks.

  • Corrosion exposure without proper maintenance can shorten lifespan.

  • Always ensure plates are certified to ASTM/IS standards and sourced from reliable suppliers.
