High Pressure Boiler Tube - Product Detailed Description
1. Product Overview
High pressure boiler tube is a specialized seamless steel pipe, manufactured from high-quality carbon steel and alloy heat-resistant steel through hot rolling, cold drawing and precise heat treatment processes. It is a key pressure-bearing component specially designed for boilers and relevant heat exchange equipment, capable of long-term service under extreme working conditions including high temperature, high pressure, alternating load and steam corrosion.
With superior performances such as high temperature resistance, high pressure resistance, creep resistance, oxidation resistance and excellent structural stability, this product is widely applied in main steam pipes, superheaters, reheaters and headers of power station boilers, industrial boilers, thermal power plants and other high-temperature heat equipment. It complies with international advanced standards and is exported to overseas markets including Turkey, Malaysia, Nigeria, Sri Lanka, the United Kingdom, Israel and other countries and regions.
2. Executive International Standards
• GB/T 5310-2023 (Chinese National Standard for Seamless Steel Tubes for High Pressure Boilers)
• ASTM A213 / ASME SA213 (American Standard for Seamless Ferritic and Austenitic Alloy Steel Tubes for Boilers, Superheaters, and Heat Exchangers)
• ASME SA335 (American Standard for Seamless Ferritic Alloy Steel Pipe for High Temperature Service)
• EN 10216-2 / EN 10216-3 (European Standard for Seamless Steel Tubes for Pressure Purposes)
• Customized standards for overseas projects such as SADARA S175, Israel 4466 are also available upon customer requirements
3. Main Material Grades
Carbon Steel Grades
20G, 20MnG, 25MnG
Low Alloy Heat-Resistant Steel Grades
15CrMoG, 12Cr1MoVG, 12Cr2MoG
High Alloy Heat-Resistant Steel Grades

• Wall Thickness: 1.5mm - 60mm
• Length: Fixed length (6m, 9m, 12m) or random length, customized length available as per customer demand
• Processing Technology: Hot rolled (hot expanded), cold drawn, normalized & tempered, heat treated
5. Core Product Performances
• High Pressure Resistance: Withstand rated working pressure up to 10-32MPa, meeting the pressure requirements of subcritical and supercritical boilers
• High Temperature Resistance: Long-term service temperature ranges from 450℃ to 650℃, no deformation or performance attenuation under high temperature
• Good Weldability: Excellent welding performance, convenient for on-site installation and pipeline connection
• Corrosion Resistance: Strong resistance to steam oxidation and high-temperature gas corrosion, prolonging service life
• High Dimensional Accuracy: Strictly controlled outer diameter, wall thickness and straightness tolerance, meeting precision assembly requirements
6. Application Scenarios
• Utility power station boilers and industrial high-pressure boilers
• Boiler superheaters, reheaters, main steam pipelines and headers
• High-temperature heat exchange equipment in petrochemical, thermal power and energy industries
• High-pressure pipeline systems for thermal power generation projects
• Overseas boiler supporting projects and power station construction projects
7. Packaging & Transportation
• Packaging: Standard export fumigation-free steel frame packaging, woven cloth packaging, or customized wooden box packaging; both ends of the pipe are protected with plastic caps to prevent damage during transportation
• Transportation: Suitable for sea transportation and land transportation, in line with international export packaging standards, avoiding product collision and deformation
