Product Description

Product Parameters

 

The seamless stainless steel pipes offered by WUXI TONGNO SPECIAL STEEL CO.,LTD are defined by their long, hollow sections and seamless construction, providing unparalleled resistance to corrosion from both weak corrosive media like air, steam, and water, as well as chemical-impregnating substances such as acids, alkalis, and salts. Often referred to as stainless acid-resistant steel pipes, these pipes are synonymous with durability and reliability.

Features Introduction:
Firstly, a greater wall thickness enhances economic efficiency and practicality, while a thinner wall can significantly increase processing costs. Secondly, the manufacturing process dictates performance limitations; generally, seamless steel pipes offer low precision with non-uniform wall thickness, reduced interior brightness, high size correction costs, and the presence of black spots that are difficult to eliminate. Thirdly, these pipes require offline processing for thorough inspection and shaping. Thus, they excel in applications demanding high-pressure tolerance, high strength, and robust mechanical structure.
Our stainless steel seamless pipes exhibit remarkable resistance to air, steam, and water, in addition to their resilience against aggressive chemical media such as acids, alkalis, and salts. Often referred to as stainless acid-resistant steel pipes, they are essential for environments demanding high corrosion resistance.
The exceptional corrosion resistance of our stainless steel seamless pipes is largely attributed to the alloying elements present, with chromium playing a pivotal role. When chromium content reaches approximately 12%, it reacts with oxygen to form a self-passivation film on the steel's surface, preventing further corrosion. In addition to chromium, elements such as nickel, molybdenum, titanium, niobium, copper, and nitrogen are incorporated to tailor the steel's structure and properties for diverse applications.

For Usage:
These versatile stainless steel seamless pipes are integral to various industries, including petroleum, chemical, medical, food, light industry, machinery, and instrumentation. Their lightweight nature, combined with high bending and torsion strength, makes them ideal for manufacturing mechanical parts and engineering structures. They are also frequently utilized in producing conventional weapons, gun barrels, and artillery shells due to their robust structural integrity.

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