Stainless steel seamless pipes are widely preferred for demanding applications requiring high corrosion resistance, strength, pressure resistance and reliable performance at elevated temperatures. They are commonly used in oil & gas, petrochemical, refinery, chemical processing, power generation, heat exchangers and other critical piping systems.
Our range includes:
Additional grades can be supplied according to customer specifications and availability.
Alliance Pipes & Fittings also supplies Stainless Steel Welded, ERW and EFW Pipes for industrial piping, fabrication and process applications.
The appropriate manufacturing process, grade, dimensions and testing requirements can be selected according to the operating conditions and project specification.
Our stainless steel pipe portfolio covers a wide range of Austenitic Stainless Steel and Specialty Stainless Steel grades.
SS 304 and SS 304L Pipes are widely used because of their excellent corrosion resistance, fabrication properties and versatility. They are commonly specified for general industrial, chemical, food processing, pharmaceutical and process applications.
SS 316 and SS 316L Pipes offer enhanced corrosion resistance and are widely used in chemical processing, marine, pharmaceutical, petrochemical and other demanding environments.
SS 310S Pipes are designed for applications requiring excellent high-temperature performance and resistance to oxidation and scaling, including furnace, heater, refinery and heat-treatment applications.
SS 321 and 321H Pipes are stabilized stainless steel grades suitable for elevated-temperature applications where resistance to intergranular corrosion and high-temperature service is important.
SS 347 and 347H Pipes are stabilized grades used in high-temperature applications, including petrochemical, refinery and power generation equipment.
SS 904L / UNS N08904 Pipes provide excellent corrosion resistance for highly demanding chemical and process applications.
254 SMO / UNS S31254 Pipes are high-alloy austenitic stainless steel pipes designed for applications requiring exceptional resistance to chloride-induced corrosion and aggressive environments.
