Stainless steel pipes are versatile, hollow, long circular steel tubes that play a crucial role across various industries, including petroleum, chemical, medical, food, light industry, and mechanical instrumentation. These pipes are essential for transporting industrial materials and forming structural components. Due to their high bending and torsional strength combined with light weight, they are also extensively used in manufacturing mechanical parts and engineering structures. Moreover, stainless steel pipes are a popular choice for furniture and kitchenware, reflecting their widespread utility and adaptability.
Stainless steel pipes come in a diverse range of types such as ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, bimetal composite pipes, and coated pipes. These variations are designed to save precious metals and meet specific application needs. With production capabilities spanning outer diameters from 0.1mm to 4500mm and wall thicknesses from 0.01mm to 250mm, stainless steel pipes cater to a multitude of uses and technical requirements. They are typically classified to highlight their unique properties and functionalities.

Application Requirement
Automobile Industry Applications
In the automotive industry, stainless steel is predominantly used in exhaust systems, which account for over half of the stainless steel used in cars. About 80% of this is ferritic stainless steel. The exhaust system, which includes components like the muffler, intake pipe, front pipe, hose, converter, and center pipe, primarily utilizes steel types such as 409L and 436L. Stainless steel welded pipes are extensively used in mufflers. It's estimated that the automotive sector consumes roughly 1.5% of the total stainless steel pipe production, with a usage ratio of stainless steel seamless pipes to welded pipes of approximately 2:1.
Petrochemical Industry and Fertilizer Industry
The petrochemical industry heavily relies on stainless steel seamless pipes, especially for applications requiring durable and high-performance materials. Common specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are essential for constructing furnace tubes, material conveyance tubes, and heat exchanger tubes, playing a critical role in supporting medium and low-pressure pipelines with diameters above 159mm.
Water, Gas, and Fluid Transport
Stainless steel pipes are considered the most advanced materials for water transport equipment globally, offering unmatched corrosion resistance compared to cast iron, carbon steel, and plastic pipes. These properties make them indispensable in various applications.
For water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel pipes are the optimal choice. The annual demand for these pipes in the water industry is approximately 25,000 tons, underscoring their significance in maintaining high-quality water infrastructure.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance industry consumes over 20,000 tons of stainless steel pipes annually. This sector predominantly uses sanitary or antibacterial-grade stainless steel pipes. Imported SUS304 and 316L seamless pipes meet the stringent requirements of various media in food and biopharmaceutical industries. Antibacterial stainless steel, with its superior properties, is in high demand for kitchen equipment, food industry worktables, medical equipment, daily-use tableware, towel brackets, refrigerators, and more.
