Stainless steel pipe is a type of hollow, long, circular steel extensively employed in various industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation. These pipes are integral for industrial transportation and mechanical structural components. Their unique combination of bending and torsional strength, coupled with a lightweight build, makes them ideal for manufacturing mechanical parts and engineering structures. Additionally, stainless steel pipes are frequently utilized in furniture and kitchenware applications due to their versatility and strength.
Stainless steel pipes are categorized into several types including ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, bimetal composite pipes, and coated pipes. These various types cater to different uses, technical requirements, and production methods. The outer diameter of currently produced steel pipes ranges from 0.1mm to 4500mm, with wall thickness spanning 0.01mm to 250mm. To distinguish their characteristics, steel pipes are typically classified by specific methods, aiding in the identification and selection process for specific applications.

Application Requirements
Automobile Industry
In the automotive sector, stainless steel is predominantly used in exhaust systems, which account for over half of the total stainless steel usage in vehicles-with 80% being ferritic stainless steel. The exhaust system channels engine emissions through components such as the muffler, exhaust intake pipe, front pipe, hose, converter, and center pipe. Commonly used steel types in these systems include 409L and 436L. Automotive mufflers primarily employ stainless steel welded pipes. Approximately 1.5% of the total downstream stainless steel pipe consumption is attributed to automotive applications, with a usage ratio of stainless steel seamless pipes to welded pipes being about 2:1.
Petrochemical Industry, including the Fertilizer Industry
The demand for stainless steel pipes in the petrochemical industry is substantial. This sector predominantly uses stainless steel seamless pipes, with specifications including 304, 321, 316, 316L, 347, and 317L. These pipes typically have an outer diameter ranging from 18mm to 610mm and a wall thickness between 6mm to 50mm. Common applications are in furnace tubes, material conveyance tubes, and heat exchanger tubes, particularly for pipelines under medium and low pressure with diameters above 159mm.
Water, Gas, and Other Fluid Transport
Stainless steel pipes and their associated water transport equipment are recognized as the most advanced and reliable materials for basic water purification globally. Their superior corrosion resistance sets them apart from cast iron, carbon steel, and plastic pipes.
For water preparation, storage, transportation, purification, regeneration, desalination, and other water industry needs, stainless steel pipes are the best material choice. The annual demand for these pipes is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The annual consumption of stainless steel pipes in equipment manufacturing and maintenance exceeds 20,000 tons. This industry primarily utilizes sanitary or antibacterial grade stainless steel pipes. Sanitary seamless pipes made from imported SUS304 and 316L meet the stringent requirements of various media in the food and biopharmaceutical fields. Antibacterial stainless steel combines the benefits of stainless steel with excellent antibacterial properties, driving demand in kitchen equipment, food industry worktables, utensils, medical equipment, daily life tableware, hanging towel brackets, and refrigeration equipment.
