Our stainless steel seamless pipes stand as a testament to the pinnacle of modern engineering. These hollow wonders are circular, long, and crafted for unmatched versatility. Industries like petroleum, chemical, medical, food, light industry, and mechanical instrumentation have widely embraced them as essential components for industrial transportation and structural elements. With their lightweight nature, combined with robust bending and torsional strength, they have become indispensable in the creation of mechanical parts, engineering frameworks, as well as furniture and kitchenware.
The remarkable family of stainless steel pipes encompasses 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. Each is meticulously designed to conserve precious metals and meet unique requirements. This versatile collection boasts a multitude of types, uses, technical specifications, and production methods. We offer an impressive range of steel pipe outer diameters from a minuscule 0.1mm to an expansive 4500mm, with wall thicknesses ranging from an ultra-thin 0.01mm to a solid 250mm. For ease of understanding, we categorize these pipes based on their distinctive characteristics.

Application Requirement
Automobile Industry Applications
In the ever-evolving automotive industry, stainless steel plays a pivotal role, especially in exhaust systems, comprising over half of the stainless steel found in vehicles. An impressive 80% of this is ferritic stainless steel. Exhaust gases journey through components such as the intake pipe, front pipe, hose, converter, and center pipe, culminating their path in the muffler. Predominant steel types for exhaust systems include 409L and 436L, with stainless steel welded pipes being prevalent. Within the automotive domain, stainless steel pipes account for about 1.5% of total downstream consumption, with a notable seamless-to-welded pipes ratio of 2:1.
Petrochemical and Fertilizer Industry Applications
In the petrochemical sector, the demand for our stainless steel pipes is immense, with a preference for stainless steel seamless pipes. Available specifications include 304, 321, 316, 316L, 347, 317L, and more, with outer diameters from 18mm to 610mm and wall thicknesses from 6mm to 50mm. These pipes are crucial in roles such as furnace tubes, material transport tubes, and heat exchanger tubes, especially in medium to low-pressure pipelines with diameters exceeding 159mm.
Water and Gas Fluid Transport
Our stainless steel pipes and their associated water transport equipment are heralded as the zenith of modern water purification materials. Their exceptional corrosion resistance elevates them above traditional cast iron, carbon steel, and plastic pipe alternatives.
Stainless steel stands unrivaled in activities such as water preparation, storage, transportation, purification, regeneration, and desalination. The annual demand for these premium pipes reaches an impressive 25,000 tons.
