ASTM A312 Seamless Pipes: Seamless, welded, and highly cold-worked austenitic stainless steel pipes are all covered under the ASTM A312 standard specification. It includes austenitic, ferritic, and duplex stainless steels and a broad range of pipe diameters and grades. Oil and gas, chemical, and food processing industries often employ ASTM A312 seamless pipes.
It covers a variety of pipe diameters, schedules, and grades, including well-known stainless steel grades like 304, 316, and 321. Industries like oil and gas, chemical processing, pharmaceuticals, and food processing frequently employ these pipes. The ASTM A312 standard includes standards for testing, mechanical qualities, and other things.

AISI 446 Stainless Steel Pipe: Ferritic stainless steel alloy AISI 446 is renowned for its outstanding resistance to high-temperature oxidation and corrosion. It has a high chromium content and only trace amounts of molybdenum, which help it withstand heat. Applications for AISI 446 stainless steel tubes include heat exchangers, exhaust systems, combustion chambers, and sections of furnaces. The mechanical qualities of these tubes can sustain temperatures of up to 1200 °C (2200 °F). A particular type of stainless steel from the ferritic family is designated as AISI 446. It offers exceptional resistance to corrosion and oxidation at high temperatures because of the high quantities of chromium and minor amounts of molybdenum it contains. In applications involving high-temperature conditions, such as furnace and heat exchanger components, AISI stainless steel seamless 446 pipes are frequently employed.

ASTM A249 Steel Pipe: An industry standard for welded austenitic steel boilers, superheaters, heat exchanger, and condenser tubes is ASTM A249. It includes stainless steel tubes fabricated from all grades, including austenitic, ferritic, and duplex stainless steels. Steel pipes made to ASTM A249 are frequently used in heat transfer equipment in petrochemical, chemical processing, and power generation sectors. It applies to stainless steel tubes constructed from grades 304, 316, and 321. Many industries use these pipes extensively, including power generation, chemical processing, pharmaceuticals, and food processing. Dimensions, mechanical qualities, production processes, and non-destructive testing are all specified by ASTM A249.

SS 446 Welded Pipes: Stainless steel grade 446, a ferritic, heat-resistant alloy, is referred to as SS 446. Stainless steel grade 446 is used to create SS 446 welded pipes by joining pieces of the material. These pipes are appropriate for use in furnace equipment, oil refineries, chemical plants, and other high-temperature situations because of their outstanding resistance to high-temperature corrosion and oxidation. Welded pipes offer strength, cost-effectiveness, and longevity compared to seamless pipes. Stainless steel grade 446, a ferritic alloy with high heat resistance, is referred to as SS 446. Stainless Steel Seamless 446 Pipes is used to create SS 446 welded pipes. These pipes are used in high-temperature-resistant applications such as furnace parts, exhaust systems, and chemical processing machinery.
