Products Description
Our Advantages
1. Strong Corrosion Resistance
Our Stainless Steel U Tubes are made of high-quality stainless steel, offering excellent resistance to oxidation, rust, and chemical corrosion, making them particularly suitable for chemical and marine environments.
Through chemical composition testing and salt spray testing, the pipes are guaranteed to withstand corrosion from chlorides, oxidants, and high temperatures.
2. High Temperature Resistance
Our pipes exhibit thermal stability, operating effectively at temperatures up to 900°C. They remain unaffected or deformed under thermal cycling, making them ideal for industries such as petrochemicals and aerospace.
3. High Pressure Resistance
Our pipes are seamless, manufactured using a cold-drawing process, eliminating weld seams and ensuring uniform overall mechanical strength. This makes them ideal for high-pressure systems such as heat exchangers, boilers, and chemical reactors.
4. Surface Quality
Our pipes undergo pickling, passivation, and polishing, resulting in a high-gloss surface finish that prevents the accumulation of scale, debris, or other particles, reducing the likelihood of pipe damage during use.
5. Quality Control
TORICH pipes undergo rigorous testing before entering the finished goods warehouse to ensure they meet JIS G3459 standards or customer requirements, and possess certifications such as PED, ATÜV, ISO 9001, ISO 14001, and CE.
6. Packaging and Transportation
Our pipes are packaged using plastic caps, plastic film, woven bags, and wooden crates to prevent damage or contamination during transportation. We offer various shipping options, including land, sea, and air freight, and samples are available.
