Product Overview:

We proudly present our 321, 304, and 304L stainless steel seamless high-pressure tube pipes, known for their exceptional corrosion resistance, high strength, and excellent machinability. Our products are meticulously designed and manufactured to meet the demands of various high-pressure applications. With polished finish and annealing treatment, they boast smooth surfaces and strong corrosion resistance, suitable for liquid-based and gas-based applications in demanding environments.

Key Features:

1. Stainless Steel Grades for Demanding Applications
   Crafted from 321, 304, and 304L stainless steel, these tubes deliver exceptional versatility and reliability in high-pressure environments. Each grade is selected for its specific properties—321 offers improved high-temperature resistance, while 304 and 304L provide excellent corrosion resistance and weldability across a broad range of industrial applications.

2. Seamless Construction for Enhanced Integrity
   Manufactured using seamless technology, these tubes eliminate welded seams to ensure uniform structural strength and consistent wall thickness. This construction method minimizes potential failure points, enhancing safety and performance in critical fluid and gas handling systems.

3. High-Pressure Performance Capability
   Engineered to maintain integrity under extreme pressure conditions, these tubes are ideal for hydraulic systems, pneumatic controls, and precision instrumentation applications. Their robust design ensures reliable operation in demanding industrial environments where pressure resistance is paramount.

4. Precision Polished Surface Finish
   Each tube undergoes specialized polishing treatment to achieve a smooth, consistent surface. This finish not only enhances aesthetic appeal but also improves corrosion resistance and facilitates easier cleaning—particularly beneficial in sanitary, food processing, or high-purity applications.

5. Annealed for Optimal Material Properties
   Through controlled annealing processes, the tubes achieve improved ductility, reduced internal stresses, and enhanced mechanical consistency. This thermal treatment ensures the material maintains its structural integrity during fabrication and throughout its service life.

6. Comprehensive Size Availability
   Available in standard outer diameters including 1/4-inch and 3/8-inch sizes, these tubes accommodate diverse system requirements across industrial, commercial, and specialized applications. Custom sizes can be produced to meet specific project specifications.

7. Quality Assurance and Compliance
   Manufactured in accordance with international standards including ASTM A269 and A213, each production batch undergoes rigorous testing for dimensional accuracy, pressure rating, and material composition to ensure consistent quality and performance reliability.
