Product Overview
20G / ASTM A210 Gr.A1 carbon steel seamless boiler tube is widely‑used medium‑high temperature seamless tube for thermal power station and industrial boiler systems, manufactured conforming to GB/T 5310 and ASTM A210 standards. This carbon steel grade is designed for heat‑exchange components working under medium pressure and temperature up to 480℃.
Typical service parts include boiler water‑wall panels, economizer coils, low‑temperature superheater sections. Each pipe batch undergoes mechanical property test, chemical composition analysis, hydro‑static pressure test and non‑destructive flaw detection to eliminate internal defects. Outer diameter range 16‑630mm, wall thickness 2.5‑80mm, both fixed length and random cutting length can be customized according to boiler engineering drawing requirements. Export seaworthy packaging with steel end caps to protect pipe ends during long‑distance ocean transportation. Suitable for new boiler construction and boiler spare‑part replacement projects worldwide.

FAQs
20G (GB/T5310) and ASTM A210 Gr.A1 are functional equivalent carbon boiler tube grades for medium‑high temperature boiler service, slight difference on chemical tolerance; cannot direct 1‑to‑1 material substitution without engineering confirmation.
Long‑term recommended service temperature ≤480℃; do not use for working condition above 500℃, select Cr‑Mo alloy grades for higher temperature.
Standard MOQ 5 tons. For small project trial order, please contact sales to check available stock.
Yes, we offer custom fixed‑length cutting service. Tolerance will follow boiler tube international standards.
Waterproof inner paper, plastic thread‑protective end caps, bundled by galvanized steel strap, loaded into seaworthy wooden pallets for container transport.
