View Details →Peru's heavy industries—specifically the deep mining facilities in regions like Arequipa, Ancash, and Cajamarca, combined with massive marine aquaculture processing plants along the Pacific coastline—face unique challenges. Operations are subjected to high atmospheric salt concentrations, extreme altitudes, and aggressive chemical processing agents (such as sulfuric acid used in copper extraction). Heat exchangers must function under severe thermal and mechanical stresses.
Traditional piping materials fail rapidly due to localized pitting, crevice corrosion, and stress corrosion cracking (SCC). Our special alloy coiled tubing and heat exchanger pipes are specifically engineered with precise concentrations of Chromium, Nickel, and Molybdenum (such as 316L, Duplex 2205, and Super Duplex 2507). This robust metallurgy provides high resistance to chlorides, acidic leach solutions, and corrosive processing environments, assuring long operational lifespans with minimal maintenance overhead.
As an industry-leading manufacturer with over a decade of dedication to specialty tubing, we operate six state-of-the-art production lines specialized in high-performance stainless steel coiled tubing, seamless capillary tubes, and heat exchanger pipes. We execute production strictly in accordance with international standards, including GB, ASTM, ASME, JIS, and EN specifications.
Our metallurgy range covers Austenitic steels 304/304L, 316L, 321, 317L, 309S, 310S, alongside advanced alloys like Incoloy 800, Incoloy 825, Inconel 625, Duplex 2205, and Super Duplex 2507. By integrating online bright annealing systems, we ensure that every tube delivered has an ultra-clean, scale-free inner surface. This delivers high corrosion resistance and high-efficiency thermal conductivity, matching the exact demands of heavy industries worldwide.
Our ongoing mission is to solve complex engineering challenges through metallurgical excellence. Whether for offshore oil platforms in deep seas, high-altitude mineral extraction systems in Peru, or medical-grade biotechnology loops, we deliver unmatched material reliability.
Engineered to perform in high-stress, corrosive industrial environments. Match the proper alloy to your project parameters.
| Material Grade | Key Chemical Characteristics | Primary Advantages for Peru Projects | Recommended Applications |
|---|---|---|---|
| 316L (EN 1.4404) | Low carbon, 2.0-3.0% Molybdenum | Outstanding resistance to localized pitting in mild chloride environments. | Mining acid leaching, food processing, geothermal steam lines. |
| Duplex 2205 (S32205) | Dual phase microstructure (Ferritic-Austenitic) | Double the mechanical strength of standard austenitic steel with high SCC resistance. | Seawater cooling systems, copper concentrator tailings, marine pipes. |
| Super Duplex 2507 (S32750) | High Cr, Mo, N content (PREN ≥ 41) | Extremely high resistance to chloride stress corrosion cracking and erosion. | Desalination heat exchangers, acidic oil well completion loops. |
| Incoloy 825 (N08825) | Nickel-Iron-Chromium with Molybdenum & Copper | Exceptional resistance to sulfuric, nitric, and phosphoric acids. | Mining autoclaves, chemical reactors, acid processing plant cooling. |
| Inconel 625 (N06625) | Nickel-Chromium alloy with Mo & Niobium | Virtually immune to chloride-induced stress corrosion; high thermal stability up to 982°C. | High-temperature industrial exhaust condensers, petrochemical piping. |
We do not just produce raw tubing; we provide fully fabricated, project-ready solutions tailored to detailed specifications.
We provide precision-engineered spiral coiling, U-bending, and complex geometry profiles matching targeted shell-and-tube or plate-and-shell designs, minimizing on-site structural joints.
Our continuous, online bright annealing treatment runs under a controlled protective hydrogen-nitrogen atmosphere, eliminating oxides and producing high-gloss, ultra-clean surface profiles.
Every meter of tubing undergoes a comprehensive battery of tests, including flaring, flattening, hardness, 100% hydrostatic, pneumatic, and eddy current examinations to verify zero defect rates.
