Product Description

Stainless steel pipe is a type of hollow, elongated circular steel renowned for its versatility across various industries. Predominantly used in sectors such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation, it serves as a vital transport pipe and structural component. Notably, its high bending and torsional strength coupled with lightweight properties make it ideal for manufacturing mechanical parts and engineering structures. Beyond industrial use, stainless steel pipes are also commonly found in furniture and kitchenware applications.
Stainless steel pipes encompass a wide variety, including 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. Additionally, coated and lined pipes are available to conserve precious metals and fulfill specific needs. Each type of stainless steel pipe comes with unique uses, technical specifications, and production methodologies. Available in diameters ranging from 0.1mm to 4500mm and wall thicknesses from 0.01mm to 250mm, stainless steel pipes are meticulously classified for distinct characteristics and applications.

Application requirement
Folding automobile industry
In the automotive industry, stainless steel plays a pivotal role, especially in exhaust systems, which consume over half of the stainless steel used in vehicles, with ferritic stainless steel accounting for 80%. Components such as mufflers, exhaust gas intake pipes, front pipes, hoses, converters, and center pipes, predominantly utilize steel types like 409L and 436L. Stainless steel welded pipes are primarily used in mufflers, with the automotive sector consuming approximately 1.5% of the total downstream stainless steel pipe production. The usage ratio of stainless steel seamless pipes to welded pipes stands at about 2:1.
The folding petrochemical industry includes the fertilizer industry
The petrochemical industry shows significant demand for stainless steel seamless pipes. 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 furnace tubes, material conveying tubes, heat exchanger tubes, and medium to low-pressure pipelines, typically above 159mm in diameter.
Folding water and gas and other fluid transport
Stainless steel pipes, along with their corresponding water transport equipment, represent the pinnacle of modern water purification materials, boasting unrivaled corrosion resistance. Their durability far exceeds that of cast iron, carbon steel, and plastic pipes, making them the superior choice for fluid transport.
Ideal for applications such as water preparation, storage, transportation, purification, regeneration, and desalination, stainless steel pipes are the material of choice across the water industry. The annual demand for these high-performance pipes reaches approximately 25,000 tons.
Folding equipment manufacturing and maintenance
With annual consumption exceeding 20,000 tons, the equipment manufacturing and maintenance sector relies heavily on sanitary or antibacterial grade stainless steel pipes. Imported SUS304 and 316L sanitary seamless pipes meet the stringent requirements of various media in the food and biopharmaceutical fields. Antibacterial stainless steel, combining exceptional durability with hygienic properties, is increasingly sought after in the production of kitchen equipment, food industry worktables, utensils, medical equipment, tableware, and domestic items such as towel brackets and refrigerators.
