Product Description

Product Parameters

 

The Stainless Steel Seamless Pipe is a marvel of modern engineering, crafted with a hollow section and devoid of seams, designed to withstand the rigors of weak corrosive media such as air, steam, and water, as well as the challenging conditions presented by chemical-impregnating substances like acids, alkalis, and salts. Known for its resilience, this pipe is often referred to as the stainless acid-resistant steel pipe, a testament to its durability and adaptability in various corrosive environments.

Features Introduction:
Firstly, the economic and practical advantages of the product increase with wall thickness, while a thinner wall dramatically escalates processing costs. Secondly, due to its manufacturing process, the seamless steel pipe generally exhibits lower precision with non-uniform wall thickness and reduced internal brightness, leading to higher costs for size adjustments and challenges in removing internal black spots. Thirdly, these pipes must undergo offline processing for detection and shaping, showcasing their superiority in applications requiring high pressure, high strength, and robust mechanical structure materials.
The Stainless Steel Seamless Pipe stands as a paragon of strength, offering resistance against air, steam, water, and weak corrosive media, as well as formidable chemical corrosive media such as acids, alkalis, and salts. Known as the stainless acid-resistant steel pipe, its design is engineered to excel in challenging environments.
The remarkable corrosion resistance of the Stainless Steel Seamless Pipe is attributed to the alloying elements within. Chromium is the pivotal component, imparting corrosion resistance when present at approximately 12%. It interacts with oxygen in corrosive media to form a self-passivation film, effectively halting further steel matrix corrosion. Alongside chromium, other alloying elements like nickel, molybdenum, titanium, niobium, copper, and nitrogen are incorporated to tailor the pipe's characteristics for diverse applications.

For Usage:
Renowned for its versatility, the Stainless Steel Seamless Pipe finds extensive applications across industries such as petroleum, chemical, medical, food, light industry, machinery, and instrumentation. Its reduced weight without compromising bending and torsion strength makes it ideal for mechanical parts and engineering structures. Additionally, it serves crucial roles in producing conventional weapons, including gun barrels and artillery shells.
