Product Description

Product Parameters

 

Our stainless steel seamless pipes are an exceptional category of long steel, characterized by their hollow section and seamless design. These pipes are engineered to withstand corrosion from weak corrosive agents such as air, steam, and water, as well as from aggressive agents like acids, alkalis, and salts. Familiarly known as stainless acid-resistant steel pipes, they offer unmatched durability.

Distinctive Features Introduction:
To begin with, a greater wall thickness enhances economic and practical use, while a thinner wall significantly increases processing costs. Moreover, the inherent process of manufacturing this product dictates its performance limitations. Typically, seamless steel pipes exhibit low precision, with non-uniform wall thickness, lower brightness inside the tube, and a high cost for precise sizing. Additionally, the interior may show black spots that are challenging to remove. Offline processing is required for detection and shaping, showcasing its superiority in high-pressure, high-strength, mechanical structural applications.
Stainless steel seamless pipes excel in resisting air, steam, water, and other mild corrosive media, as well as more aggressive chemical agents like acids, alkalis, and salts. Known as stainless acid-resistant steel pipes, they provide robust protection against corrosion.
The remarkable corrosion resistance of our stainless steel seamless pipes is attributable to the alloying elements within the steel. Chromium is the pivotal element granting corrosion resistance, forming a minimal oxidative film (self-passivation film) when its content reaches approximately 12%, thus averting further corrosion. Besides chromium, these pipes often contain alloying elements like nickel, molybdenum, titanium, niobium, copper, and nitrogen, tailored to meet various organizational and property requirements of stainless steel.

Versatile Usage Applications:
These pipes find extensive application across industries such as petroleum, chemical, medical, food, light industry, machinery, and instrumentation, serving essential roles in industrial pipelines and mechanical structural components. Their lighter weight, combined with equal bending and torsion strength, makes them ideal for manufacturing mechanical parts and engineering structures. Additionally, they are prevalent in crafting conventional weaponry, including gun barrels and artillery shells.

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