Super Austenitic 12" Diameter 904L Stainless Steel Tube 1.1" Wall Thickness Stainless Steel Pipe

Stainless Steel Pipe Product Description1. Product Parameter Table

2. Product Details

Our stainless steel pipes are manufactured from high-quality raw materials (such as 304, 316, and duplex steel) through precision processes like cold-drawing and hot-rolling, ensuring dimensional accuracy (diameter tolerance ±0.02mm, wall thickness tolerance ±0.01mm). The pipe body is free from sand holes, cracks, or depressions, with a smooth, burr-free inner wall that reduces fluid transport resistance. Surface treatments support diverse customizations: pickling (enhances corrosion resistance), polishing (Ra≤0.8μm, suitable for sanitary scenarios), and mirror finishing (Ra≤0.08μm, meets decorative needs). Each batch undergoes eddy current testing, water pressure testing (no leakage under 10MPa), and composition analysis to ensure compliance with international standards.

3. Product Applications

Stainless steel pipes, with their excellent performance, are widely used in various fields:

Industrial sector: Chemical pipelines (transporting acid-alkali solutions), petroleum refining pipelines (resistant to high temperature and pressure), water treatment systems (corrosion resistance);

Construction sector: Curtain wall supports, handrails (304 material for rust resistance), water supply and drainage pipes (sanitary-grade 316L);

Medical sector: Medical device delivery tubes (17-4PH material, high strength and easy to clean);

Food industry: Food processing equipment pipelines (304 food-grade, compliant with FDA standards);

New energy sector: PV bracket connecting pipes (2205 duplex steel, strong weather resistance).

4. Product Performance Advantages

Corrosion Resistance: 316 and 316L contain molybdenum, resistant to chloride ion corrosion, suitable for coastal and chemical environments; 304 is ideal for general atmospheric and freshwater environments.

High-Temperature Resistance: 310S and 309S can work continuously at 800-1200℃, suitable for kilns and heat treatment equipment.

High Strength: 2205 duplex steel has a tensile strength ≥620MPa and yield strength ≥450MPa, 30% higher than ordinary austenitic steel.

Easy Machinability: 416 and 303 materials contain sulfur, offering excellent machinability for precision part processing; 301 has good ductility, suitable for bending and stamping.

Sanitary Performance: Polished inner walls of 304/316 pipes prevent bacterial growth, meeting food-grade and medical-grade requirements.
