Product Description

Product Parameters

 

Our stainless steel seamless steel pipe is crafted for excellence, featuring a sleek, hollow section that is seamlessly continuous. Designed to resist corrosion caused by mild corrosive agents such as air, steam, and water, as well as more intense chemical environments involving acids, alkalis, and salts, this pipe stands as a testament to durability and strength. Commonly referred to as a stainless acid-resistant steel pipe, it promises longevity and reliable performance.

Features Introduction:
The product's economic and practical value increases with wall thickness, while reduced thickness raises processing costs significantly. Its manufacturing process dictates performance limitations, as standard seamless steel pipes often exhibit low precision, inconsistent wall thickness, subdued internal surface brightness, high size-stabilization costs, and internal surface blemishes that are challenging to eliminate. Offline processing is necessary for comprehensive inspection and shaping, showcasing its superiority in applications demanding high pressure, strength, and robust mechanical structure.
Our stainless steel seamless pipes excel in resisting corrosion from air, steam, water, and chemical environments laden with acid, alkali, and salt. These pipes, known for their stainless acid-resistant properties, offer an ideal solution for a wide range of applications.
The exceptional corrosion resistance of our seamless stainless steel pipes is primarily due to the alloying elements infused within the steel. Key among these is chromium, which, upon reaching about 12% content, interacts with environmental oxygen to create a thin, yet resilient oxide layer on the steel surface - a self-passivation film that halts further corrosion. Complementing chromium, elements like nickel, molybdenum, titanium, niobium, copper, and nitrogen are also employed to tailor the steel's structure and properties, meeting diverse usage demands.

For Usage:
The versatility of our stainless steel seamless pipes allows them to shine across an array of industries - from petroleum and chemical sectors to medical, food, light industry, and machinery manufacturing. Their reduced weight, coupled with superior bending and torsion strength, makes them ideal for engineering structures and mechanical components. Moreover, their application extends to the production of military essentials, including gun barrels and artillery shells, underscoring their role in defense manufacturing.

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