View SpecificationsUruguay's industrial sector is undergoing a major technological upgrade, led by massive pulp mill investments along the Rio Uruguay and Rio Negro (such as the UPM and Montes del Plata operations), modern food processing centers, and dairy cooperatives (such as CONAPROLE). These sectors demand high-performance piping systems that can withstand hot acidic chemicals, high-pressure steam, and strict hygienic protocols.
In chemical and pulp operations, standard piping often suffers from stress corrosion cracking (SCC) at welded joints. Using continuous coiled stainless steel tubing eliminates up to 90% of the fittings and orbital welds required in traditional pipe runs. This significantly reduces leak risks and inspection costs, and allows for rapid deployment in complex routing environments.
For marine supply hubs and dry docks near Montevideo and Nueva Palmira, the use of Duplex (2205) and Super Duplex (2507) coiled lines provides superior resistance to chloride-induced pitting, making it the preferred choice for instrumentation, control lines, and chemical injection umbilicals.
Globally, deepwater offshore oil and gas developments and high-pressure hydrogen fueling grids are pushing materials to their limits. Coiled tubing must be engineered to withstand severe environments, including sour gas exposures (high H2S) and ocean currents.
Liaocheng Sihe Stainless Steel Material LTD designs tubing to satisfy demanding international standards, including ASTM A269 for general corrosion-resisting services, ASTM A249 for boilers and heat exchangers, and ASTM A789 for duplex alloys. Our super-long, continuous coiled lines (extending up to 32,800 feet or 10,000 meters) without orbital welds are critical for undersea control umbilicals, where any weld represents a potential point of failure.
We supply a complete portfolio of austenitic, duplex, and nickel-alloy coiled tubing. All orders are customized with certified mechanical properties, precise dimensional tolerances, and strict surface treatments.

At Liaocheng Sihe Stainless Steel Material LTD, we run a state-of-the-art on-line bright annealing line. This process heats the cold-drawn tubing in a controlled hydrogen/nitrogen atmosphere. The result is a scale-free, mirror-like finish on both inner and outer surfaces, which preserves the alloy’s corrosion resistance and prevents oxide contamination during subsequent fabrication or fluid routing.
Our QA laboratory carries out a series of testing protocols, including pneumatic air-tightness tests, hydrostatic pressure tests up to customer-specified levels, flaring and flattening tests to verify ductility, hardness tests, and microscopic grain structure evaluations.
Sourcing direct from our production facility in Liaocheng, Shandong Province, provides major commercial advantages. We balance competitive bulk raw material sourcing with highly efficient, automated extrusion and cold-drawing lines. This enables us to offer competitive mill-direct pricing to buyers in Uruguay, Nueva Palmira, and Montevideo without quality compromises.
We offer flexible production scheduling to meet demanding project deadlines, custom packaging designed for international transport (including heavy-duty plywood reels and moisture-barrier shrink wraps), and full documentation packages for Uruguayan customs clearance.
