Product Details

Advantage:

Sophisticated bright annealing technology makes the tube good mechanical performance,the tube can be flared, flatten, bent freely.


Product Performance:

1.Superior Corrosion Resistance: High-purity stainless steel material effectively resists acid, alkali, moisture and chemical corrosion, suitable for harsh working environments. 
2.Stable Mechanical Properties: Uniform material structure, high tensile strength and pressure resistance, not easy to deform under high pressure and high temperature conditions.
3.High Dimensional Precision: Strict tolerance control for outer diameter, wall thickness and length, ensuring perfect assembly and matching for precision machinery. 
4.Multiple Surface Finishes: Professional BA/AP/EP surface treatment removes impurities, achieving smooth, clean and oxidation-free tube surface.  
5.Long Service Lifespan: Wear-resistant and durable, reducing maintenance and replacement costs for industrial equipment.


Application:

Our stainless steel tube/pipe is specially designed for industries with stringent material standards, widely applied in various high-precision and heavy-duty fields:

1.Automotive Manufacturing: Fluid transmission pipelines and structural components for automobile systems.  
2.Precision Engineering: High-precision tubular parts for mechanical equipment and instrumentation.  
3.Hydraulic & Pneumatic Piping: Pressure-resistant pipelines for hydraulic and pneumatic transmission systems.  
4.Heat Exchange Equipment: High-temperature resistant tubes for heat exchangers and cooling systems.  
5.Mining Machinery: Anti-corrosion structural pipes for mining heavy machinery.  
6.Aerospace Industry: Critical lightweight and high-strength aerospace components.  
7.Chemical & Petroleum Industry: Chemical fluid transportation under extreme conditions.
