In global industrial piping systems, alloy steel pipes are essential for high-temperature, high-pressure, and corrosive environments, playing a key role in power generation, petrochemicals, and boiler applications. Among global standards, ASTM A335 and ASTM A213 represent the highest quality levels for seamless alloy steel tubes in elevated-temperature service.
Our Specialization: A335 & A213 Products
ASTM A335 – Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service
A335 pipes are designed for high-temperature and high-pressure conditions, such as superheaters, main steam lines, refineries, and utility boilers. Common grades include P11, P22, and P91. These materials offer excellent creep-rupture strength and oxidation resistance, ensuring long-term safe operation.
ASTM A213 – Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
A213 covers small-diameter tubes widely used in boiler water walls, superheater tubes, reheater tubes, and heat exchanger bundles. Typical grades include T11, T22, T91 (ferritic) and TP304, TP316 (austenitic). Strict dimensional tolerances and internal surface quality ensure heat transfer efficiency and extended equipment lif
Our Core Strengths

Sufficient stock & value-added services: Large inventory of various sizes with cutting, beveling, and heat treatment available.
Cost-effective logistics for India & Thailand: Well-established sea and land shipping routes ensure fast delivery.
Focus on India & Thailand Markets
India – Rapidly Growing Energy & Infrastructure Hub
India is undergoing massive power capacity expansion, refinery upgrades, and city gas network projects. A335 P91/P22 and A213 T91/T22 are essential for supercritical boilers and petrochemical heaters. We regularly supply Indian EPC contractors and traders, with deep understanding of BIS certification and project acceptance requirements.
Thailand – Southeast Asia’s Industrial & Energy Powerhouse
Thailand is one of ASEAN’s largest manufacturing bases for petrochemical and power equipment. Many boiler factories, heat exchanger plants, food processing facilities, and waste-to-energy projects demand A213 alloy and stainless tubes. We offer cut-to-length small-diameter tubes and fast customs clearance support to reduce inventory costs.
