High-tolerance options suitable for marine processing and precision controls.
As Northern Vietnam's paramount maritime gateway and logistics core, the city of Hai Phong is experiencing an unprecedented industrial expansion. Driven by deep-water harbors like Lach Huyen Port and high-tech zones including the Dinh Vu-Cat Hai Economic Zone, the region has transitioned from standard manufacturing to precision engineering, automotive fabrication, advanced shipbuilding, and petrochemical storage.
In these environments, exposure to aggressive marine atmospheric salinities, extreme humidity, and chemical process agents is constant. Standard metals degrade rapidly, causing expensive downtime. That is why industries across Hai Phong rely on Grade 316 stainless steel capillary tubing. Formulated with a molybdenum content of 2.0% to 3.0%, Grade 316 provides superior resistance to chloride-induced pitting and crevice corrosion compared to basic chromium-nickel alloys like 304.
From the control loops in chemical processing units near the port to the subsea hydraulic controls used by maritime operators off the Gulf of Tonkin, premium capillary tubing ensures consistent pressure management, precise sensor telemetry, and reliable fluid delivery systems.
Max Continuous Coiled Tubing Length
Ultra-Fine Inner Diameter Tolerance Capability
Hydrostatic & Eddy Current Tested Quality Assurance
Deciphering chemical configurations and dimension specifications for critical environments.
The staple for petrochemical routing, offering low carbon content (316L) to prevent intergranular sensitization during custom welding and processing operations in humid environments.
For applications where extreme mechanical strength meets heavy marine corrosiveness. Provides double the mechanical yield strength of standard austenitic alloys.
Superalloys built specifically for high-pressure downhole instrumentation, sour gas pipelines, and offshore umbilicals subject to severe acid and chloride attack.
Liaocheng Sihe Stainless Steel Material LTD manufactures and supplies high-performance coiled and capillary tubing within an outer diameter spectrum ranging from 0.125 inch (3.175 millimeters) to 1 inch (25.4 millimeters), with wall thicknesses spanning up to 0.165 inch (3 millimeters). Continuous lengths of up to 32,800 feet (10,000 meters) are available to minimize orbital welds and connectors, thereby removing potential leakage zones in high-pressure hydraulic pipelines.
Our technical roadmap integrates specialized internal cleanroom cleaning protocols, guaranteeing the zero-contamination levels necessary for chromatography systems, precision medical instruments, and electronic fluid control mechanisms.
In today's fast-moving industrial sector, a dependable supply chain is essential. Liaocheng Sihe Stainless Steel Material LTD operates six state-of-the-art production lines designed to meet tight schedules and demanding specifications.
By utilizing the latest bright annealing technology, we execute in-line softening and grain structure refinement, producing tubing with clean, smooth interior and exterior surfaces. Our facility is equipped with automated systems for compression, flaring, flattening, hardness check, tensile strength testing, and 100% pneumatic/hydrostatic seal verification.
Located near major shipping corridors, we deliver directly to Hai Phong Port. This allows local distributors and procurement teams to benefit from competitive factory prices, reliable deliveries, and a stable supply of precision tubing that meets international quality standards.
