Product Description

Product Parameters

 

Unveiling the Stainless Steel Seamless Pipe, a revolutionary long steel with a sleek, hollow section devoid of seams. Crafted for excellence, this pipe stands strong against the corrosive forces of air, steam, water, and even aggressive chemical environments like acids, alkalis, and salts. Known also as the stainless acid-resistant steel pipe, it embodies the pinnacle of corrosion resistance technology.

Features Introduction:
1. Economic Efficiency: A thicker wall signifies better economic viability, while a thinner wall increases processing costs substantially. 2. Precision Limits: Due to manufacturing processes, general seamless pipes have low precision, with uneven wall thickness and dull internal surfaces, which require costly resizing. The inner surface may also have persistent black spots. 3. Offline Processing: Essential for pipe detection and shaping, showcasing its prowess in high-pressure and high-strength applications, making it ideal for mechanical structural materials.
The stainless steel seamless pipe is engineered to resist corrosion from air, steam, water, acids, alkalis, and salts, thus earning its name as the stainless acid-resistant steel pipe.
The unparalleled corrosion resistance of our stainless steel seamless pipe is attributed to the alloying elements in the steel. Chromium serves as the core element, granting corrosion resistance when its content reaches approximately 12%, forming a protective oxidative film on the steel surface that wards off further corrosion. Additional alloying elements like nickel, molybdenum, titanium, niobium, copper, and nitrogen are utilized to enhance the performance and versatility of the stainless steel for a myriad of applications.

For Usage:
Versatile and durable, the stainless steel seamless pipe finds extensive use across industries such as petroleum, chemical, medical, food, light industry, and machinery. It serves as a vital component in industrial pipelines and mechanical structures. Its lightweight properties, combined with substantial bending and torsion strength, make it a preferred choice in manufacturing mechanical parts and engineering frameworks. Additionally, its robust nature sees it used in producing conventional weapons, including gun barrels and artillery shells.

Standard:
GB/T 14976 - The Prestigious Chinese National Standard
EN10216-5 - The Esteemed European Union Standard
ASME SA312 - The Acclaimed American Society of Mechanical Engineers (ASME) Standards
