High Temperature 310S Seamless Stainless Steel Pipe 6-813mm OD for Furnace Service

This high temperature seamless stainless steel pipe is manufactured from 310S (1.4845) austenitic stainless steel, an alloy engineered for sustained service in oxidizing and high-temperature environments. With elevated chromium and nickel content, 310S delivers exceptional resistance to oxidation, sulfidation, and carburization at temperatures up to approximately 1100 degrees Celsius, far exceeding the capability of conventional 304 or 316 grades. The seamless construction ensures uniform wall thickness and eliminates weld seams that could act as initiation points for thermal fatigue and creep. Available in outer diameters from 6 mm to 813 mm with wall thicknesses from 0.5 mm to 60 mm, the pipe is produced in standard 6-meter and custom cut lengths. Each batch is fully traceable with mill test certificates, making it a reliable choice for long-service, high-temperature installations.

• High Temperature Strength: retains mechanical integrity at continuous temperatures up to 1100°C.
• Oxidation Resistance: high chromium and nickel content resists scaling and oxidation.
• 310S Alloy: outperforms 304 and 316 grades in sustained elevated-temperature service.
• Seamless Construction: no weld seam reduces thermal fatigue and creep initiation.
• Thermal Stability: resists carburization and sulfidation in combustion atmospheres.
• Full NDT Coverage: ultrasonic, eddy current, and hydrostatic testing on every length.

The 310S seamless stainless steel pipe is the preferred choice for furnace components, radiant tubes, heat treatment baskets, kiln furniture, thermal oxidizers, and other high-temperature process piping. In heat treatment facilities, it withstands repeated heating and cooling cycles without losing dimensional stability or developing premature oxidation. In industrial furnaces and boilers, the alloy resists the corrosive effects of hot combustion gases, sulfur compounds, and carbon-bearing atmospheres that rapidly degrade ordinary stainless grades. The pipe is also used in petrochemical heaters, waste incinerators, and metal processing equipment where reliable high-temperature performance is essential. Its combination of oxidation resistance, thermal stability, and structural integrity delivers extended service life and reduced maintenance in demanding thermal environments.

Each pipe is protected with plastic end caps and wrapped before being assembled into steel-strapped bundles or packed into seaworthy wooden cases for export. This packaging prevents surface damage and contamination during ocean and road transport. Every shipment is accompanied by complete mill test certificates covering chemical composition, mechanical properties, and NDT results. Manufacturing is performed under an ISO 9001:2015 certified quality management system, with optional third-party inspection by SGS or BV available to meet project requirements.
