Stainless steel pipe is a versatile hollow, long circular steel extensively used across various industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation for industrial transportation and mechanical structural components. It boasts equal bending and torsional strength, coupled with a lightweight profile, making it an ideal choice for manufacturing mechanical parts and engineering structures. Additionally, stainless steel pipes are popular in the creation of furniture and kitchenware.
Stainless steel pipes come in a broad spectrum of varieties, including ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, and bimetal composite pipes. These variants are designed to conserve precious metals and fulfill special requirements by incorporating coatings and special compositions. Depending on their application, technical requirements, and production methods, stainless steel pipes are classified into numerous types. Currently, the production range for steel pipes includes an outer diameter spanning from 0.1mm to 4500mm, and a wall thickness ranging between 0.01mm to 250mm. The classification methods used help in distinguishing the unique characteristics of each steel pipe.

Application requirement
Folding automobile industry
In the automotive industry, stainless steel is predominantly utilized in the exhaust system, which constitutes over half of the total stainless steel used in automobiles, with 80% being ferritic stainless steel. The exhaust gases emitted by the automobile engine are routed through a series of components, including the exhaust gas intake pipe, front pipe, hose, converter, and center pipe, before reaching the muffler. Commonly used steel types in the exhaust system include 409L and 436L, with automobile mufflers mainly employing stainless steel welded pipes. Stainless steel pipes utilized in automobiles account for approximately 1.5% of the downstream stainless steel pipe consumption, with a usage ratio of stainless steel seamless pipes to welded pipes being about 2:1.
The folding petrochemical industry includes the fertilizer industry
The demand for stainless steel pipes in the petrochemical industry is substantial, focusing predominantly on stainless steel seamless pipes. Specifications mainly include 304, 321, 316, 316L, 347, and 317L, with outer diameters ranging from 18mm to 610mm and wall thicknesses spanning from 6mm to 50mm. These pipes are typically selected for medium and low-pressure pipelines above Φ159mm. Key application areas encompass furnace tubes, material conveying tubes, and heat exchanger tubes.
Folding water and gas and other fluid transport
Stainless steel pipes and their associated water transport equipment represent the pinnacle of advanced basic water purification materials available today. Their exceptional corrosion resistance outperforms that of cast iron pipes, carbon steel pipes, and plastic pipes, ensuring superior durability and reliability.
In the water industry, stainless steel is the ideal material for water preparation, storage, transportation, purification, regeneration, and desalination processes. The annual demand stands at approximately 25,000 tons.
Folding equipment manufacturing and maintenance
The equipment manufacturing and maintenance industry consumes over 20,000 tons of stainless steel pipes annually, primarily involving sanitary or antibacterial grade pipes. Made from imported SUS304 and 316L, these sanitary seamless pipes cater to the stringent requirements of various media in the food and biopharmaceutical sectors. Antibacterial stainless steel combines the benefits of stainless steel with excellent antibacterial properties, making it increasingly sought after for kitchen equipment, food industry worktables and utensils, medical equipment, tableware, towel brackets, refrigerators, and more.
