We are a manufacturer for stainless steel coiled tube, producing stainless steel coiled tubing including Inconel 625 Tubing which are High Performance Alloy tubing. Alloy 625 Tubing is a material with excellent resistance to pitting, crevice and corrosion cracking. Nickel 625 tubing is highly resistant in a wide range of organic and mineral acids, with good high temperature strength. These tubing are characterized by high resistance to oxidation at elevated temperatures up to 1050C and known for good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis, making possible the construction of thin structural parts of high heat transfer. These Alloy 625 Seamless Tubing are mainly used by Oil and gas production where hydrogen sulfide and high corrosion resistant applications are required.
We are a leading manufacturer of a wide size range & wall thickness in Inconel 625 Seamless Tubing for aerospace, chemical & Pharma industry. For high corrosion resistant applications, Alloy 625 Welded tubing is the best option and used to manufacture Aircraft components. Alloy 625 exhaust tubing is a useful material to manufacture high quality tubing for oil & gas, Food Processing as well power generation Industries.

Our manufacturing facility features three production lines of stainless steel coiled tube and stainless steel pipe. With exporting experience for more than ten years, we offer processes including bending, stretching, saw cutting, stamping, and polishing. Our products are widely used in bathroom pendants, hanger accessories, hardware, condensation water heating equipment, and hotel supplies. We look forward to cooperating with both domestic and foreign customers based on drawings or samples.
Alloy 625 features high mechanical strength and excellent resistance to pitting, crevice corrosion, and oxidation at elevated temperatures up to 1050°C. It is highly resistant to a broad range of organic and mineral acids like sulfuric, phosphoric, nitric, and hydrochloric acids.
Our standard size range for outer diameters is 6.52mm to 25.4mm, with wall thicknesses starting from 0.2mm to 2.0mm. Continuous length per coil typically ranges from 300 meters to 3500 meters depending on specification requirements.
Seamless coiled tubing is the first choice for critical applications because it eliminates the risk of impurities often found in welded tubing joints. It also reduces the need for multiple fitting connections, significantly lowering the risk of system leaks.
We manufacture coiled pipes in multiple grades, including TP304, TP316L, 304, 316, 310S, Duplex 2205, 825, and Alloy 625 among others, ensuring compliance with ASTM A269/A249 specifications.
To ensure structural integrity, the tubes undergo bright annealing inline softening treatment followed by strict quality testing including flaring, compression, bending, 100% hardness tests, tensile testing, and air tightness testing.
Our coiled tubing products are widely used in refrigeration equipment, heat exchangers, evaporators, condensation water heating equipment, aerospace aircraft components, petrochemical projects, CNG piping, instrumentation, and oil and gas subsea applications.
