seamless steel tubes

When your boiler runs at 650°C and 150 bar, there’s no room for error. The wrong tube doesn’t just cause downtime—it creates safety risks, regulatory nightmares, and multi-million dollar losses. At Shanghai Maxmetal, we supply premium seamless boiler tubes engineered to thrive under extreme conditions, meeting the world’s most stringent standards.   Why Standards Matter: Decoding the Alphabet Soup Not all boiler tubes are created equal. Different applications demand specific material properties. That’s why we stock four core standards, each a benchmark in its own right: ASTM A179: The Heat Transfer Champion Low-carbon seamless steel designed for one job: moving heat efficiently. Perfect for surface condensers and heat exchangers where thermal conductivity is king. ASTM A192: The High-Pressure Workhorse When your boiler system demands brute strength, A192 delivers. Engineered for high-pressure carbon steel applications, it’s the backbone of reliable steam generation. ASME SA213: The Alloy Power Player Chrome-moly alloys (T11/T12/T22) built for superheaters and reheaters. These tubes laugh at temperatures up to 650°C, resisting creep and oxidation when ordinary steel would fail. For ultra-critical applications, grades like T91 and T92 add vanadium, niobium, and nitrogen for next-level performance. DIN 17175: The European Standard-Bearer German-engineered alloy grades like 15Mo3 and 13CrMo44 ensure compliance with European projects while delivering exceptional high-temperature strength. TU 14-3P-55-2001: The Russian Standard For projects requiring Russian certification, this standard ensures full compliance with GOST-equivalent quality requirements for high-pressure boilers. What Makes Our Boiler Tubes Battle-Ready? Creep Resistance: Up to 650°C continuous operation without deformation Oxidation Protection: Withstands aggressive flue gas environments Seamless Reliability: No welds mean no weak points Global Compliance: One supplier, multiple certifications—simplifying your procurement Size Flexibility: Outer diameter from 15mm to 630mm, wall thickness 1.5mm to 35mm Every tube undergoes mandatory hydrostatic testing, eddy current inspection, and ultrasonic testing. We supply EN 10204 3.1/3.2 certification and maintain full traceability from billet to finished product. From Raw Steel to Precision Tube: Our Manufacturing DNA Quality isn’t an accident—it’s engineered into every step: Raw Material Validation: Billets are sampled, analyzed, and inspected before cutting. No surprises. Hot Forming: Precision heating and piercing creates a flawless hollow shell, followed by annealing to refine grain structure. Cold Drawing: Multiple drawing passes with phosphating and lubrication achieve exact dimensions and superior surface finish. Heat Treatment: Controlled processes ensure optimal mechanical properties and microstructure. Rigorous Inspection: Surface inspection, NDT, and PMI (Positive Material Identification) guarantee chemistry and integrity. Final Validation: Straightening, cutting, marking, and a final quality review before hexagonal packing and dispatch. This isn’t just a process—it’s a quality obsession that eliminates risk from your supply chain. Where Our Tubes Perform   Power Generation: Supercritical and ultra-supercritical boilers, heat recovery steam generators (HRSG) Petrochemical: Process heaters, reformer tubes, cracking furnaces Industrial Heat Transfer: High-temperature exchangers and condensers Global Infrastructure: Projects requiring multi-standard compliance   Simplify Your Procurement, Amplify Your Performance Juggling multiple suppliers for ASTM, DIN, and ASME tubes?
