it can withstand extreme temperatures ranging from -196℃ to 800℃ without deformation at high temperatures or brittleness at low temperatures; it has outstanding compressive strength, capable of withstanding pressures above 1.6MPa, and passes the water pressure test without leakage.
Key Advantages
Outstanding Corrosion Resistance
Forms a dense protective chromium oxide film, resisting atmospheric, moisture and mild chemical corrosion.
Service life is 5–8 times longer than carbon steel pipes, ideal for humid and corrosive environments.
Excellent Processability
Uniform wall thickness enables direct bending, cutting and welding with smooth, burr-free welds.
No complex grinding needed, greatly improving installation efficiency.
Hygienic & Safe
Complies with food‑contact standards, non‑toxic and heavy‑metal free.
Smooth surface inhibits bacterial adhesion, easy to clean for food and medical applications.
Superior Cost Performance
Stable quality, low maintenance over lifetime and fully recyclable.
More cost-effective and supply-reliable than copper tubes, balancing economy and sustainability.
