Product Description

Product Parameters

 

Introducing the Stainless Steel Seamless Steel Pipe, an ingenious creation of long steel characterized by its hollow section and seamless design. This exceptional steel pipe stands robust against corrosion by mild corrosive agents such as air, steam, and water, and also holds strong against chemical-infused media like acid, alkali, and salt. Often hailed as the stainless acid-resistant steel pipe, this product is a testament to durability and reliability.

Features Introduction:
Firstly, an increase in wall thickness significantly enhances the economic value and practicality of the product; conversely, a reduction leads to a sharp rise in processing costs. Secondly, the inherent process of creating this product influences its performance limitations: typically, seamless steel pipes have lower precision with uneven wall thickness, low internal brightness, and high costs for size adjustments. Moreover, they may have unsightly surface blemishes such as black spots that are difficult to remove. Thirdly, offline processing is essential for testing and formation, underscoring its superiority in applications requiring high pressure, strength, and mechanical structure materials.
The stainless steel seamless pipe exhibits remarkable resistance to air, steam, water, and other mild corrosive media, as well as to acids, alkalis, salts, and other chemical corrosive environments. This resilience has earned it the moniker of the stainless acid-resistant steel pipe.
The secret to the exceptional corrosion resistance of stainless steel seamless pipes lies in their alloy composition. Chromium, a fundamental element, enables stainless steel to achieve its anticorrosive properties. When the chromium content reaches approximately 12%, it reacts with oxygen in corrosive environments to form a protective oxidative layer (self-passivation film) on the steel surface, thwarting further corrosion of the steel core. Beyond chromium, commonly used alloying elements such as nickel, molybdenum, titanium, niobium, copper, and nitrogen are incorporated to meet diverse functional and structural requirements of stainless steel.

For Usage:
Stainless steel seamless pipes are extensively utilized across a multitude of sectors including petroleum, chemical, medical, food, light industry, machinery, and instrumentation. Their lightweight nature, combined with substantial bending and torsion strength, make them indispensable in crafting mechanical parts and engineering structures. Additionally, they find usage in the manufacturing of various conventional weapons, gun barrels, and artillery shells.
