High Temperature Boiler Pipe Thick Wall Heat Resistant Steel Pipe ASTM ASME SA210C SA210GrC SA210A1

Industrial Seamless Steel Pipes & Tubes: Premium Solutions for Critical Applications

Our product portfolio covers a comprehensive range of ASTM/ASME and API-compliant seamless steel pipes, boiler pipes, heat exchanger tubes, superheater tubes, and alloy steel pipes, engineered to meet the strictest industrial standards for high-performance and reliability. From the widely used SA106B/GrB, A106C/GrC, and SA53B/A53GrB to specialized grades like SA210C/GrC, A333Gr6/Gr8, and API Spec5L, each product is precision-manufactured to cater to critical applications in power generation, oil & gas, chemical processing, and heavy industry. Every pipe and tube undergoes rigorous quality control to ensure consistency in dimensions, material composition, and mechanical properties—aligning with the "thick wall," "precision size," and "corrosion resistant" attributes highlighted in our product lineup.

Product Details: Precision Engineering for Industrial Durability

All our seamless steel pipes and tubes are manufactured via the hot-rolled or cold-drawn seamless process, eliminating weld seams to enhance structural integrity and resistance to high pressure and fatigue—critical for applications where leakage or failure risks are unacceptable. The "smooth inner wall" design minimizes fluid flow resistance, making them ideal for heat exchangers and fluid transport systems, while "thick wall" variants (available for SA106C, SA210C, and API Spec5L) provide extra structural support for heavy-duty scenarios like boiler headers and high-pressure pipelines.

Each product adheres to strict dimensional tolerances: outer diameter tolerance of ±0.5mm, wall thickness tolerance of ±0.1mm, and length tolerance of ±5mm—ensuring easy installation and compatibility with standard industrial fittings. For custom requirements, we offer "precision cut" services (with cut length tolerance of ±1mm) and can adjust wall thickness, outer diameter, and material composition to match specific project needs, such as low-temperature corrosion resistance for A333Gr3/Gr8 or high-temperature strength for SA210A1/GrA1.

Product Applications: Powering Key Industries Globally

Our pipes and tubes are designed to excel in diverse industrial environments, with material grades and specifications tailored to sector-specific demands:

? Power Generation: SA210C/GrC and SA210A1/GrA1 boiler pipes & superheater tubes are used in thermal power plants, where they withstand high-temperature steam (up to 650°C) and cyclic pressure loads. A333Gr6 pipes are deployed in cooling systems for their low-temperature resistance (-45°C).

? Oil & Gas: API Spec5L and SA53B/A53GrB seamless steel pipes are the backbone of oil and gas transmission pipelines, handling high pressure (up to 100MPa) and corrosive media (e.g., crude oil, natural gas). A333Gr8 pipes are used in offshore platforms for their resistance to saltwater corrosion.

? Chemical Processing: SA106B/GrB and A106C/GrC heat exchanger tubes facilitate efficient heat transfer in chemical reactors and distillation columns, while their corrosion resistance ensures compatibility with acids, alkalis, and solvents.

? Heavy Industry: Alloy steel pipes (SA106GrB/GrC) are used in manufacturing equipment (e.g., pressure vessels, hydraulic systems) for their high strength (tensile strength ≥ 485MPa) and wear resistance, reducing maintenance costs and extending equipment lifespan.

Product Performance: Reliability Backed by Material Science

The performance of our pipes and tubes is rooted in their high-quality material composition and rigorous testing:

? High Temperature Resistance: SA210C/GrC contains chromium (0.15-0.35%) and manganese (0.40-0.70%), enabling it to maintain strength at 650°C without deformation. SA106C/GrC adds silicon (0.10-0.40%) for enhanced oxidation resistance at high temperatures.

? High Pressure Capacity: Thick-wall API Spec5L pipes (wall thickness ≥ 10mm) have a burst pressure of over 100MPa, making them suitable for high-pressure fluid transport. SA53B pipes feature a minimum yield strength of 250MPa, ensuring structural stability under heavy loads.

? Corrosion Resistance: A333Gr3/Gr8 is alloyed with nickel (0.40-0.70%) and copper (0.10-0.30%), providing excellent resistance to low-temperature corrosion and saltwater exposure. SA106B/GrB’s carbon content (0.25-0.30%) enhances resistance to general industrial corrosion.

? Mechanical Strength: All products undergo tensile testing (minimum elongation of 20%), impact testing (Charpy V-notch impact energy ≥ 27J at -20°C), and hardness testing (Brinell hardness ≤ 187HB), ensuring they meet ASTM/ASME mechanical property requirements.
