Product Description

Stainless steel pipe is a versatile long circular hollow steel extensively used across various industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation. It serves crucial roles in industrial transportation and mechanical structural components. In addition to its impressive bending and torsional strength, its lightweight nature makes it an excellent choice for crafting mechanical parts and engineering structures. Furthermore, it finds widespread application in furniture and kitchenware manufacturing.
Stainless steel pipes are categorized into multiple types: ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, and bimetal composite pipes, among others. These pipes may also feature coatings to conserve precious metals and meet unique requirements. The diverse array of stainless steel pipes caters to different uses, technical requirements, and production methods. Currently, steel pipes are produced with outer diameters ranging from 0.1-4500mm and wall thicknesses from 0.01-250mm. To highlight their distinct characteristics, stainless steel pipes are typically classified by the following criteria.

Application Requirements
Automobile Industry
In the automotive sector, stainless steel is primarily used in exhaust systems, which account for over half of the stainless steel utilized in vehicles. Approximately 80% of this is ferritic stainless steel. The automobile exhaust system, which includes components such as the exhaust gas intake pipe, front pipe, hose, converter, and center pipe, frequently uses types 409L and 436L stainless steel. The mufflers mainly use stainless steel welded pipes. It is estimated that the automotive industry consumes around 1.5% of the total downstream stainless steel pipes, with a usage ratio of stainless steel seamless pipes to welded pipes being about 2:1.
Petrochemical Industry and Fertilizer Industry
The petrochemical industry has a significant demand for stainless steel pipes, particularly seamless varieties. Specifications include 304, 321, 316, 316L, 347, 317L, with outer diameters ranging from 18-¢610mm and wall thicknesses from 6mm to 50mm. Common applications within this industry include furnace tubes, material conveying tubes, and heat exchanger tubes.
Water, Gas, and Fluid Transport
Stainless steel pipes, along with their associated water transport equipment, represent the pinnacle of advanced water purification materials today. Their exceptional corrosion resistance sets them apart, making them superior to cast iron, carbon steel, and plastic pipes.
For the water industry, including preparation, storage, transportation, purification, regeneration, and desalination, stainless steel is the ideal material choice. The annual demand for these applications stands at approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance industries consume over 20,000 tons of stainless steel pipes annually. These industries predominantly use 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 marries the benefits of standard stainless steel with superb antibacterial properties, driving demand in kitchen equipment, food industry worktables, utensils, medical equipment, daily life tableware, towel brackets, refrigerators, and more.
