Product Description

Product Parameters

 

Our Stainless Steel Seamless Pipes are designed as long steel structures with a hollow section, free from any seams around the circumference. These pipes are heralded for their unparalleled resistance to corrosion by mild corrosive media such as air, steam, and water, as well as chemical-impregnating media including acids, bases, and salts. This exceptional property makes them known as stainless acid-resistant steel pipes.

Features Introduction:
Firstly, the economic and practical benefits rise with increased wall thickness, while a decrease in wall thickness leads to a substantial increase in processing costs. Secondly, the inherent processes define the performance limitations: general seamless steel pipes often lack precision, with uneven wall thickness, low internal brightness, high size-fixing costs, and persistent black spots. Despite these challenges, they exhibit superiority in high-pressure and high-strength mechanical structural applications. Thirdly, offline processing is essential for detection and shaping, underscoring their advantage in demanding environments.
Our stainless steel seamless pipes excel in resisting corrosion from air, steam, water, and other mild corrosive media, in addition to enduring the corrosive attacks of acids, bases, salts, and other chemical media. This distinctive capability earns them the title of stainless acid-resistant steel pipes.
The corrosion resistance of our stainless steel seamless pipes is attributable to their alloy composition. Chromium is the cornerstone element, achieving corrosion resistance when its content reaches approximately 12%. By forming a thin oxidative self-passivation film upon exposure to oxygen in corrosive environments, chromium prevents further corrosion of the steel matrix. Beyond chromium, other alloying elements like nickel, molybdenum, titanium, niobium, copper, and nitrogen contribute to meeting diverse structural and property requirements.

For Usage:
Our stainless steel seamless pipes are extensively utilized across various industries, including petroleum, chemical, medical, food, light industry, machinery, and instrumentation. Their lightweight nature, coupled with superior bending and torsion strength, makes them ideal for manufacturing mechanical parts and engineering structures. Additionally, they play a crucial role in producing conventional weapons, gun barrels, artillery shells, among other applications.
