ASTM A213 seamless alloy steel pipes from Big Co., Ltd. are manufactured for high-temperature service in boilers, superheaters, and heat exchangers, covering ferritic and austenitic grades such as T5, T9, T11, T12, T22, T91, and T92. The pipes conform to ASTM A213M-09 standards and are supplied in OD sizes ranging from 10mm to 1020mm, with wall thicknesses between 2mm and 60mm, and lengths up to 16000mm depending on the manufacturing process (hot-rolled, cold-drawn, or hot-expanded). These tubes are designed to withstand elevated pressures and temperatures in industrial environments.
The material composition varies by grade, with chromium, molybdenum, and nickel content tailored for specific performance requirements. For example, T11 grade contains 0.5-1.0% chromium and 1.0-1.5% molybdenum, while T22 grade includes 1.90-2.60% chromium and 0.87-1.13% molybdenum. Typical mechanical properties include tensile strength ranging from 415N/mm² to 515N/mm² for ferritic grades, with elongation percentages starting at 30% for most grades. The tubes undergo rigorous testing, including chemical composition inspection, mechanical property tests (tensile, yield, elongation), and non-destructive testing such as hydrostatic and surface dimension checks.
These pipes are commonly used in power generation plants, petrochemical refineries, and fertilizer units, where reliability under extreme conditions is critical. Buyers typically source them in bulk, with trade terms such as CFR or CIF basis per metric ton. The pipes are packaged with beveled ends, black painting, plastic caps, and bundled with steel strips or wooden protection to prevent damage during transit. Surface treatments like oil-dip, varnish, or epoxy coating can be applied as requested to enhance durability.

Before ordering ASTM A213 alloy pipes from Big Co., Ltd., verify the exact grade and dimensions required for your application, as the supplier offers a broad selection of sizes and material specifications. Confirm whether the pipes are hot-rolled, cold-drawn, or hot-expanded, as this affects their mechanical properties and suitability for specific uses such as boilers or heat exchangers. Additionally, request the latest mill test certificates to ensure compliance with ASTM A213M-09 standards.
For logistics, discuss lead times and shipping terms with Big Co., Ltd., as the pipes are typically quoted on a CFR or CIF basis per metric ton. Clarify packaging requirements, such as beveled ends or specific surface treatments, to avoid delays at customs.
