Product Description

Stainless steel pipes, characterized by their hollow, long circular structure, are extensively utilized across a multitude of industries including petroleum, chemical, medical, food, light industry, and mechanical instrumentation. These pipes serve as vital components for industrial transportation and mechanical structures. Notably, they offer identical bending and torsional strength while being lightweight, making them ideal for manufacturing mechanical parts and engineering structures. Additionally, stainless steel pipes find common applications in furniture and kitchenware, offering versatility and durability in various settings.
Stainless steel pipes are categorized into a range of types including ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, and other specialized variants such as bimetal composite pipes and coated pipes. These variations help conserve precious metals and satisfy distinct operational requirements. Stainless steel pipes are produced in numerous sizes, with outer diameters ranging from 0.1mm to 4500mm and wall thicknesses from 0.01mm to 250mm. For ease of identification, steel pipes are typically classified based on their specific characteristics, uses, technical requirements, and production methods.

Application Requirement
Automobile Industry
In the automobile sector, stainless steel is predominantly used in exhaust systems, accounting for over half of the total stainless steel usage in vehicles. Ferritic stainless steel, such as types 409L and 436L, comprises 80% of this application. It is used in components including exhaust gas intake pipes, mufflers, hoses, converters, and center pipes. Stainless steel welded pipes are typically used for these parts. The automotive industry consumes approximately 1.5% of the downstream stainless steel pipe market, with a usage ratio of stainless steel seamless pipes to welded pipes being around 2:1.
Petrochemical Industry, Including Fertilizer Industry
The petrochemical sector presents a significant demand for stainless steel pipes, particularly seamless ones. 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 applications such as furnace tubes, material conveyance tubes, and heat exchanger tubes, especially in medium to low-pressure pipelines.
Water, Gas, and Fluid Transport
Stainless steel pipes serve as the premier material for water transport equipment, acclaimed globally for their superior corrosion resistance, outperforming alternatives like cast iron, carbon steel, and plastic pipes. These attributes make them the most advanced choice for water purification systems and fluid transport.
Ideal for water preparation, storage, transportation, purification, regeneration, desalination, and other water industry applications, stainless steel pipes boast an annual demand of roughly 25,000 tons, proving their indispensability in these sectors.
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. Made from premium materials like SUS304 and 316L, these pipes meet stringent requirements in the food and biopharmaceutical fields. Additionally, antibacterial stainless steel is favored for its dual benefits of hygiene and durability, making it ideal for kitchen equipment, food industry worktables, medical devices, daily use tableware, and home appliances like refrigerators and towel racks.
