Products Description
Our advantages
1. Strong Corrosion Resistance
- Our 304 Welded Stainless Steel Pipe is made of high-quality 304/304L stainless steel and has passed PMIPMI certification, ensuring compliance with quality standards. It resists most corrosive media, including weak acids, bases, and moisture.
- The pipe undergoes salt spray and intergranular corrosion testing to ensure corrosion resistance after welding.
2. High Welding Quality
- We use TIG and laser welding to produce 304 Welded Stainless Steel Pipe, ensuring uniform, clean welds free of porosity and inclusions.
- After welding, the pipe undergoes an acid wash to restore its smooth surface, ensuring no compromise in heat transfer efficiency or corrosion resistance, making it ideal for use in heat exchangers and condensers.
3. Machinability and Weldability
- Our pipes are highly machinable and can undergo secondary operations such as cutting, drilling, and finishing.
- Welding with TIG, MIG, and Laser Welding is possible, though appropriate post-weld treatment is required to restore corrosion resistance.
applications areas
- Automotive and Mechanical Systems: Used in exhaust systems, cooling circuits, and mechanical components requiring corrosion resistance.
- Industrial Applications: Compressed air, gas, and general industrial piping.
- Fluid Transportation: Building water systems, fire hoses, municipal water networks, gas distribution, etc.
- Heating, Ventilation, and Air Conditioning (HVAC): Ventilation ducts, smoke exhaust ducts, heat exchanger housings, fan systems, etc.
- Machinery Manufacturing: Frames, conveyor rollers, protective sleeves, etc. for textile, printing, and packaging machinery.
