Product Description

Stainless steel pipes are a type of hollow, long circular steel extensively used across various industries including petroleum, chemical, medical, food, light industry, and mechanical instrumentation. Its exceptional bending and torsional strength, combined with a lightweight structure, make it indispensable in the production of mechanical parts and engineering structures. Additionally, these pipes find widespread application in the furniture and kitchenware sectors due to their unique properties.
Stainless steel pipes are categorized into various types, such as ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, stainless steel pipes, and bimetal composite pipes. The diversity extends to coatings and coated pipes that conserve precious metals and fulfill specific requirements. With a myriad of uses, technical specifications, and production methods, stainless steel pipes range in outer diameter from 0.1mm to 4500mm and wall thickness from 0.01mm to 250mm. To highlight their diverse features, these pipes are classified using specific criteria.

Application Requirement
Automobile Industry
Stainless steel plays a pivotal role in the automotive industry, particularly in exhaust systems, which account for over half of the stainless steel used in vehicles. Predominantly, ferritic stainless steel is employed, with common types including 409L and 436L. Components like exhaust intake pipes, front pipes, hoses, converters, and center pipes are crucial. Mufflers, typically crafted from stainless steel welded pipes, also rely heavily on these materials. Approximately 1.5% of the total downstream consumption of stainless steel pipes is attributed to the automotive sector, with a usage ratio of seamless to welded pipes standing at roughly 2:1.
Petrochemical Industry Including the Fertilizer Sector
There is a substantial demand for stainless steel pipes in the petrochemical sector, primarily employing seamless varieties. Specifications include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses from 6mm to 50mm. Common applications encompass furnace tubes, material conveyance tubes, and heat exchanger tubes, especially for medium and low-pressure pipelines above Φ159mm.
Water, Gas, and Other Fluid Transportation
Stainless steel pipes and associated water transport equipment represent the pinnacle of modern water purification materials, boasting unparalleled corrosion resistance. Their superiority over cast iron, carbon steel, and plastic pipes is evident in various applications.
In the water industry, stainless steel pipes are the optimal choice for water preparation, storage, transportation, purification, regeneration, and desalination. The annual demand for these pipes is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing industry consumes over 20,000 tons of stainless steel pipes annually. These industries primarily use sanitary or antibacterial-grade stainless steel pipes, notably those made from imported SUS304 and 316L, to meet stringent media requirements in food and biopharmaceutical sectors. Antibacterial stainless steel combines the benefits of standard stainless steel with superior antibacterial properties, catering to the growing demand in kitchen equipment, food industry worktables, medical equipment, daily life tableware, hanging towel brackets, and refrigerators.
