Product Description

Product Parameters

 

The Stainless Seamless Steel Pipe from WUXI TONGNO SPECIAL STEEL CO., LTD is an impeccable long steel marvel, featuring a hollow, seamless design. Distinguished by its resilience to weak corrosive agents like air, steam, and water, as well as chemical agents such as acids, alkalis, and salts, this pipe is the epitome of durability and efficiency. Often hailed as the stainless acid-resistant steel pipe, it serves as a formidable ally against corrosion.

Features Introduction:
Firstly, the product's economic and practical benefits increase with its wall thickness, while thinner walls result in significantly higher processing costs. Secondly, the inherent limitations of the manufacturing process impact its performance, leading to lower precision in general seamless steel pipes: uneven wall thickness and low internal brightness, combined with high costs for sizing and challenging removal of internal black spots. These factors necessitate offline processing for detection and shaping, thus highlighting its exceptional capabilities in high-pressure, high-strength mechanical structures.
This stainless steel seamless pipe offers remarkable resistance to air, steam, water, and other mildly corrosive media, as well as potent chemical corrosive agents like acids, alkalis, and salts. It is also referred to as the stainless acid-resistant steel pipe, showcasing its extraordinary ability to withstand harsh environments.
The corrosion resistance of the stainless steel seamless pipe is largely attributed to its alloy composition. Chromium, the fundamental element, imparts corrosion resistance by forming a thin oxidative film (self-passivation film) on the steel surface once the chromium content reaches about 12%. This film prevents further corrosion of the steel matrix. Complementing chromium, other essential alloying elements include nickel, molybdenum, titanium, niobium, copper, and nitrogen, each tailored to meet diverse organizational and property requirements of stainless steel.

For Usage:
The stainless steel seamless pipe is a versatile solution, extensively utilized across various industries including petroleum, chemical, medical, food, light industry, machinery, and instrumentation sectors. Its lightweight nature, despite its equivalent bending and torsional strength, makes it ideal for manufacturing mechanical parts and engineering structures. Additionally, it's a staple in producing conventional weapons, gun barrels, and artillery shells, underscoring its wide-reaching impact.

GB/T 14976 -- Chinese National Standard
EN10216-5 -- European Union standard
ASME SA312 -- American Society of Mechanical Engineers (ASME) standards
