All of the steel plates and other steels that Taiji glass-lined equipment uses are from China well known steel plants such as Baosteel Group, Jinan Iron and Steel Group, etc. The steels are made to strict standards and meet our requirements for thickness and quality.

Our Commitment to Quality with Q345R Steel

• All steel plates used in our company are of the highest quality Q345R grade. Renowned for its exceptional strength, toughness, fatigue resistance, impact resistance, wear resistance, weldability, and ease of processing, Q345R steel is the ideal choice for demanding applications.
• As a specialized steel grade for pressure vessels, Q345R is one of the most widely used steel grades in China. It finds extensive applications in the petroleum, chemical, power generation, and boiler industries, where it is commonly used to manufacture reactors, heat exchangers, separators, gas ducts, liquefied gas tanks, boiler drums, and liquefied petroleum gas cylinders.
• For equipment that adheres to ASME standards, we exclusively utilize ASME-grade steel plates to ensure product quality, enhance performance, and meet the diverse requirements of our customers.

Q345R Steel Plate Standard Sizes

• Thickness: 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, 20mm, 22mm, 25mm, 30mm, 35mm, 40mm, 45mm, 50mm, 55mm
• Width: 1800mm, 2000mm, 2200mm, 2500mm

The corrosion curve below illustrates the corrosive nature of typical acidic and alkaline media.

• Low Corrosion Rate (<0.1 mm/year): When the corrosion rate is less than 0.1 mm per year, it indicates that the medium is minimally corrosive to glass-lined surfaces. Such media are recommended for use with glass-lined equipment.
• Moderate Corrosion Rate (0.1-0.2 mm/year): A corrosion rate between 0.1 and 0.2 mm per year suggests that the medium exhibits moderate corrosiveness towards glass-lined surfaces. Regular inspections of the glass-lined layer are necessary in these conditions.
• Severe Corrosion Rate (>0.2 mm/year): Corrosion rates exceeding 0.2 mm per year indicate a high degree of corrosiveness that can significantly damage glass-lined surfaces. The use of glass-lined equipment is not recommended in such media.

The accompanying graph shows how different media at different temperatures and concentrations corrodes, highlighting their effect on the glass-lined porcelain layer.
