Product Description

Product Parameters

 

The Stainless Steel Seamless Steel Pipe is ingeniously designed as a long, hollow-sectioned steel, meticulously crafted without any seams encircling it. This remarkable steel pipe is renowned for its exceptional resistance to corrosion, effectively withstanding weak corrosive media like air, steam, water, as well as chemically impregnating agents such as acid, alkali, and salt. Celebrated in the industry under the name of stainless acid-resistant steel pipe, it is an epitome of durability and longevity.

Features Introduction:
Firstly, the economic and practical value of the product increases with a thicker wall, whereas a thinner wall results in a significant spike in processing costs. Secondly, the processing technique dictates its performance constraints; generally, seamless steel pipes offer low precision, with non-uniform wall thicknesses and a dim internal finish. Moreover, the expense of maintaining precise dimensions is high, and internal blemishes such as black spots are challenging to eliminate. Additionally, offline processing is necessary for inspecting and shaping the pipe, showcasing its superiority in applications demanding high pressure, high strength, and robust mechanical structuring materials.
Stainless steel seamless pipe showcases excellent resilience against air, steam, water, and other weak corrosive media, as well as against chemical corrosive media like acids, alkalis, and salts. Known also as stainless acid-resistant steel pipe, it stands as a testament to advanced corrosion resistance.
The corrosion resistance of a stainless steel seamless pipe is profoundly influenced by the alloying elements within the steel. Chromium serves as the fundamental component that imparts corrosion resistance; when chromium content reaches approximately 12%, it reacts with oxygen in the corrosive environment, forming a delicate oxidative film on the steel surface (self-passivation film), effectively shielding the steel from further corrosion. Besides chromium, other alloying elements such as nickel, molybdenum, titanium, niobium, copper, and nitrogen are frequently incorporated to enhance the diverse organisational and property requirements of stainless steel for various applications.

For Usage:
The versatile stainless steel seamless pipe finds extensive use across varied industries including petroleum, chemical, medical, food, light industry, machinery, and instrumentation, serving as pivotal industrial pipelines and mechanical structural components. Its lightweight nature, coupled with equal bending and torsion strength, makes it an ideal choice for manufacturing mechanical parts and engineering structures. Additionally, it plays a crucial role in producing conventional weaponry, gun barrels, and artillery shells, further underlining its broad applicability.
