Product Description

Product Parameters

 

Discover the exceptional quality of our stainless steel seamless pipes, a hallmark of long steel innovation featuring a hollow core and no seams around its circumference. Designed to defy the corrosive impact of mild agents such as air, steam, and water, as well as chemical adversaries like acid, alkali, and salt, this steel pipe is the epitome of durability. Often referred to as a stainless acid-resistant steel pipe, it promises resilience and longevity.

Features Introduction:
1. Economic Efficiency: With increased wall thickness, enjoy greater economic and practical benefits, while thinner walls may incur higher processing costs, making thickness a crucial factor. 2. Performance Limitations: The production process inherently limits performance, with general seamless pipe precision being lower. Expect some variance in wall thickness, low internal brightness, and high costs for resizing, along with occasional internal black spots that resist removal. 3. Superior Use Cases: Offline processing for detection and shaping accentuates its superiority, especially in high-pressure, high-strength mechanical applications.
Embark on a journey of unparalleled corrosion resistance with our stainless steel seamless pipe, crafted to withstand air, steam, water, and other mild corrosive environments. Its resilience extends to chemical agents like acids, alkalis, and salts, earning its place as a stainless acid-resistant steel pipe.
The secret to the corrosion resistance of our stainless steel seamless pipe lies in its carefully selected alloying elements. Chromium, the cornerstone of this capability, initiates the formation of a protective self-passivation film when its concentration reaches about 12%, effectively shielding the steel beneath from further damage. Complemented by nickel, molybdenum, titanium, niobium, copper, nitrogen, and more, these elements fine-tune the steel's structure and properties to meet diverse applications.

For Usage:
Embrace the versatility of stainless steel seamless pipe across various industries, from petroleum and chemical sectors to medical, food, and light industries. Its mechanical prowess makes it ideal for machinery, instrumentation, and structural components. Its lightweight nature ensures efficiency without compromising strength, making it a choice material for manufacturing mechanical parts, engineering structures, and even conventional weapons like gun barrels and artillery shells.

Standard:
GB/T 14976 -- the benchmark for Chinese National Standards
EN10216-5 -- a European Union standard of excellence
ASME SA312 -- upholding the rigor of American Society of Mechanical Engineers (ASME) standards
