Product Description

Product Parameters

 

Introducing the remarkable stainless steel seamless steel pipe, a distinguished long steel product characterized by its hollow section and lack of seams. This specialized steel pipe boasts exceptional resistance to corrosion from mild corrosive elements such as air, steam, and water, as well as from chemical-infused media like acids, alkalis, and salts. Commonly referred to as the stainless acid-resistant steel pipe, it represents the pinnacle of stainless steel innovation.

Features Introduction:
To begin with, the product's wall thickness plays a crucial role in its economic value: a thicker wall ensures more practicality, while a thinner wall significantly increases processing costs. Secondly, the inherent limitations of the production process affect the performance of the product. Typically, seamless steel pipes have lower precision, with non-uniform wall thickness, low internal brightness, and high costs associated with sizing. The interior often presents pockmarks and difficult-to-remove black spots. Consequently, offline processing is necessary for detection and shaping. Despite these challenges, the seamless pipe excels in applications requiring high pressure, strength, and mechanical structure materials.
The stainless steel seamless pipe is expertly designed to resist corrosion from air, steam, water, and other mild corrosive agents, as well as from harsh chemical media like acids, alkalis, and salts. This dual resistance qualifies it as a stainless acid-resistant steel pipe, showcasing its resilience and versatility.
The excellent corrosion resistance of stainless steel seamless pipes is attributed to the alloying elements integrated into the steel. Chromium stands as the fundamental element, bestowing corrosion resistance when the chromium content reaches approximately 12%. This interaction between chromium and oxygen in the corrosive environment forms an ultra-thin oxidative layer, known as a self-passivation film, which effectively shields the steel matrix from further damage. Beyond chromium, additional alloying elements like nickel, molybdenum, titanium, niobium, copper, and nitrogen are utilized to tailor the stainless steel's structure and properties for diverse applications.

For Usage:
The versatility of stainless steel seamless pipes extends across numerous industries, including petroleum, chemical, medical, food, light industry, machinery, and instrumentation. Its lightweight nature, coupled with equivalent bending and torsion strength, makes it the ideal choice for manufacturing mechanical parts and engineering structures. Furthermore, it finds extensive application in the production of conventional weapons, gun barrels, artillery shells, and more, underscoring its multifaceted utility.
