Stainless steel seamless tubings are widely used in various industrial and civilian fields due to their excellent performance, including the petrochemical industry, energy and power industry, food and pharmaceutical industry, machinery and equipment manufacturing, automotive and shipbuilding industry, building decoration industry, and aerospace industry.
Core working advantages of stainless steel seamless tubings
1. Excellent corrosion resistance:
-Chromium content ≥ 10.5%, forming a dense oxide film that resists corrosion from various chemical media
-Specially suitable for corrosive environments such as acid, alkali, and salt, with a service life far exceeding that of ordinary steel pipes
-Different materials such as 304, 316, 316L can be selected according to the characteristics of the medium
2. Excellent mechanical performance:
-The tensile strength can reach 520-750MPa, which is 1.5-2 times that of ordinary carbon steel pipes
-Good toughness and impact resistance, suitable for dynamic load environments
-Maintaining high strength even at high temperatures, with a wide operating temperature range (-196 ℃ to 800 ℃)
3. Precise dimensions and smooth inner walls:
-Cold rolling process ensures high dimensional accuracy (tolerance ± 0.1mm)
-Internal surface roughness Ra ≤ 0.8 μ m, significantly reducing fluid resistance
-Specially suitable for transporting high-purity media to avoid product contamination
4. High safety and reliability:
-Seamless structure without weld weaknesses, with a pressure bearing capacity 20-30% higher than welded pipes
-Uniform metallographic structure to avoid local corrosion and stress cracking
-Through rigorous non-destructive testing (eddy current, ultrasonic, etc.), the quality is controllable
5. Economic and environmental advantages:
-Long lifespan reduces replacement frequency and maintenance costs
-100% recyclable, in line with the concept of green manufacturing
-No plating treatment to avoid heavy metal pollution such as zinc and chromium
6. Easy installation and maintenance:
-Multiple connection methods are available (welding, sleeve, thread, etc.)
-Various surface treatments (polishing, pickling, sandblasting, etc.) to meet different needs
-Long maintenance cycle, easy cleaning, especially suitable for clean environments
Stainless steel seamless pipes can meet various harsh working conditions through material selection (such as duplex steel, super austenitic steel, etc.) and process optimization, and are the preferred solution for modern industrial pipeline systems.
