Product Description

The stainless steel pipe we offer is a versatile, hollow, long circular steel tube extensively used across various industries such as petroleum, chemical, medical, food, light industry, and mechanical instrumentation. This multi-functional component is also integral to mechanical structures. With matching bending and torsional strength and a lightweight profile, our stainless steel pipes are ideal for manufacturing mechanical parts and engineering projects. They're also a preferred choice for fabricating furniture and kitchenware.
Our stainless steel pipes come in a variety of types, including ordinary carbon steel pipes, high-quality carbon structural steel pipes, alloy structural pipes, alloy steel pipes, bearing steel pipes, bimetal composite pipes, and coated pipes designed to conserve valuable metals and cater to special needs. These pipes are deployed for diverse applications, meeting various technical demands and produced through multiple methods. Currently, we manufacture steel pipes with an outer diameter range of 0.1-4500mm and wall thickness range of 0.01-250mm. To accurately identify their properties, stainless steel pipes are categorized based on distinct criteria.

Application Requirement
Automobile Industry
In the automotive sector, stainless steel is predominantly employed in exhaust systems, accounting for over half of the total stainless steel usage in vehicles, with 80% being ferritic stainless steel. Exhaust gases from the engine pass through the exhaust intake pipe, front pipe, hose, converter, and center pipe to the muffler. Commonly used steel types in exhaust systems include 409L and 436L. For automobile mufflers, stainless steel welded pipes are the norm. The automotive industry's consumption of stainless steel pipes is about 1.5% of the total downstream stainless steel pipe demand, with a utilization ratio of 2:1 for stainless steel seamless pipes versus welded pipes.
Petrochemical Industry, including Fertilizer Industry
In the petrochemical industry, there is a substantial demand for stainless steel pipes, primarily seamless types. Specifications include 304, 321, 316, 316L, 347, 317L, etc., with outer diameters ranging from 18-¢610 mm and wall thicknesses from 6mm to 50mm. These pipes are essential in applications such as furnace tubes, material conveying tubes, and heat exchanger tubes, especially for pipelines with medium and low pressure above Φ159mm.
Water, Gas, and Other Fluid Transport
When it comes to water transport, stainless steel pipes and related equipment represent the pinnacle of advanced water purification materials available today. Their superior corrosion resistance far exceeds that of cast iron pipes, carbon steel pipes, and plastic pipes.
In the water industry, including preparation, storage, transportation, purification, regeneration, and desalination, our stainless steel pipes are the material of choice. The annual demand in this sector is approximately 25,000 tons.
Equipment Manufacturing and Maintenance
The equipment manufacturing and maintenance sector consumes over 20,000 tons of stainless steel pipes annually. This industry mainly utilizes sanitary or antibacterial grade stainless steel pipes. Sanitary seamless pipes, crafted from imported SUS304 and 316L, satisfy the strict requirements of various media in the food and biopharmaceutical fields. Antibacterial stainless steel combines all the benefits of classic stainless steel with excellent antibacterial properties, making it increasingly popular for kitchen equipment, food industry worktables, utensils, medical equipment, tableware, towel brackets, refrigerators, and more.
