Types of Stainless Steel 446 Pipes & Tubes
Stainless Steel 446 Seamless Pipes
SS 446 seamless pipes are produced without a weld seam, giving uniform wall structure for high-temperature and industrial service. They are supplied to ASTM A731 / ASME SA731 in sizes from 1/2" NB to 24" NB across standard schedules, with plain, threaded or beveled ends. Typical uses include furnace components, heat exchanger lines and process piping exposed to oxidising atmospheres.
Stainless Steel 446 Seamless Tubes
SS 446 seamless tubes are manufactured to ASTM A268 / ASME SA268 for general corrosion-resistant and high-temperature tubing service. They are available in a range of outside diameters and wall thicknesses, in cut or random lengths. Common applications include heat exchanger and recuperator tubing, thermocouple protection tubes and boiler components.
Stainless Steel 446 Welded Pipes
SS 446 welded pipes are formed from plate or strip and welded longitudinally, offering an economical option for larger diameters and longer runs. They are supplied to ASTM A731 / ASME SA731 in standard schedules and custom lengths. Welded pipes suit ducting, exhaust and process lines operating at elevated temperatures.
Stainless Steel 446 Welded Tubes
SS 446 welded tubes are produced to ASTM A268 / ASME SA268 in round, square and rectangular sections. They are available in custom outside diameters, wall thicknesses and cut lengths. Typical uses include heat exchanger tubing, burner and combustion assemblies, and fabricated structures exposed to heat.
Stainless Steel 446 EFW Pipes
SS 446 electric fusion welded (EFW) pipes are made by fusion welding rolled plate, which makes them suitable for larger diameters and heavier walls than seamless production allows. They are fabricated to customer dimensions and schedules with plain or beveled ends. EFW pipes are used in large-bore process lines, flue gas ducting and high-temperature plant piping.
Stainless Steel 446 ERW Pipes
SS 446 electric resistance welded (ERW) pipes are formed from strip and welded without filler metal, giving consistent dimensions and a smooth finish. They are available to ASTM A731 / ASME SA731 in standard schedules and single random, double random or cut lengths. ERW pipes are commonly used for exhaust systems, heating equipment and general high-temperature piping.
Stainless Steel 446 ERW Tubes
SS 446 ERW tubes are produced to ASTM A268 / ASME SA268 with close dimensional tolerances and a uniform surface finish. They are supplied in round, square and rectangular profiles in custom sizes and cut lengths. Typical applications include heat exchanger tubing, radiant heater tubes and fabricated furnace parts.
Stainless Steel 446 Capillary Tubes
SS 446 capillary tubes are small-diameter, thin-wall tubes supplied to ASTM A268 / ASME SA268 where applicable. They are available in custom outside diameters, wall thicknesses and lengths. Capillary tubes are used for instrumentation, sensor and thermocouple sheathing, and sampling lines in high-temperature equipment.
Applications of Stainless Steel 446 Pipes & Tubes
SS 446 pipes and tubes are chosen where oxidation and scaling resistance at elevated temperatures matter more than room-temperature strength. Typical applications across the industries we serve include:
- Petrochemical & Refining: furnace tubes, heater coils and flue gas lines
- Oil and Gas: process heaters and high-temperature exhaust piping
- Chemical Processing: piping and tubing exposed to hot, sulphur-bearing atmospheres
- Power Generation & Energy: boiler components, recuperators and heat exchanger tubing
- Pharmaceuticals: heating and drying equipment lines
- Pulp & Paper: recovery boiler and kiln-related components
- Food Processing: ovens, burners and heat-treatment equipment
- Aerospace: heat-resistant test and exhaust assemblies
