Product Description

Stainless steel pipe is a versatile and essential component in modern industries. This hollow, long circular steel is extensively used across petroleum, chemical, medical, food, light industry, mechanical instrumentation, and other industrial domains for transportation pipes and structural components. Beyond its industrial applications, its combination of bending and torsional strength with lightweight properties makes it a favorite in manufacturing mechanical parts, engineering structures, and even furniture and kitchenware.
Stainless steel pipes encompass a wide array of types, including ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, and more. They also include bimetal composite pipes, coated pipes, and other variants to conserve precious metals and fulfill specialized requirements. These pipes are produced in diverse sizes, with outer diameters ranging from 0.1mm to 4500mm and wall thicknesses from 0.01mm to 250mm. To better understand their diverse characteristics, stainless steel pipes are categorized based on their specific uses, technical demands, and production methods.

Application Requirement
Automotive Industry Applications
In the automotive sector, stainless steel is predominantly used in the exhaust system, accounting for over half of the total stainless steel utilized in vehicles, with 80% being ferritic stainless steel. The exhaust system, which includes the muffler, intake pipe, front pipe, hose, converter, and center pipe, benefits from stainless steel due to its durability and efficiency. Commonly used grades in this system are 409L and 436L. The stainless steel welded pipe is the main material for mufflers, representing approximately 1.5% of the overall stainless steel pipe consumption in the automotive industry, with a usage ratio of 2:1 between seamless and welded pipes.
Petrochemical Industry Applications Including Fertilizer Industry
The petrochemical industry has a significant demand for stainless steel pipes, primarily utilizing seamless pipes in specifications such as 304, 321, 316, 316L, 347, and 317L. These pipes typically feature outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm, especially for medium and low-pressure pipelines above 159mm in diameter. Key applications include furnace tubes, material conveying tubes, and heat exchanger tubes.
Water, Gas, and Other Fluid Transport
Stainless steel pipes, along with their associated water transport equipment, are currently the pinnacle of advanced water purification materials globally. Their outstanding corrosion resistance sets them apart from cast iron, carbon steel, and plastic pipes.
For water-related industries such as preparation, storage, transportation, purification, regeneration, and desalination, stainless steel is the preferred material. The annual demand for these stainless steel solutions is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
In the equipment manufacturing and maintenance sector, the annual consumption of stainless steel pipes exceeds 20,000 tons. This industry primarily requires sanitary or antibacterial grade stainless steel pipes. Imported SUS304 and 316L sanitary seamless pipes meet the stringent requirements of various media in food and biopharmaceutical fields. The antibacterial stainless steel, combining the benefits of stainless steel with superior antibacterial properties, is increasingly demanded for kitchen equipment, food industry worktables, medical equipment, daily use tableware, and other products like towel brackets and refrigerators.
