Jiangyin Carridea: Your Trusted Partner for Precision Engineered Tubing Solutions

For over 16 years, Jiangyin Carridea Technology has stood at the forefront of precision steel tubing manufacturing, earning a reputation for excellence in cold-drawn tubes, honing tubes, hydraulic cylinder tubes, and roller-pressed tubes.  Combining advanced technology, rigorous quality control, and a customer-first philosophy, Carridea delivers high-performance tubular solutions that power industries ranging from construction and mining to metallurgy and hydraulic systems.

Uncompromising Precision in Every Dimension

Precision is the hallmark of Carridea’s products.  Equipped with state-of-the-art machinery—including hydraulic cold-drawing units, CNC honing machines, and integrated boring-rolling systems—Carridea achieves dimensional tolerances as tight as ±0.05mm.  Our cold-drawn tubes boast exceptional straightness (0.2–0.25mm/m) and roundness, while our honing tubes feature mirror-smooth internal surfaces with roughness values down to Ra 0.2–0.4μm, ensuring optimal sealing and long service life in hydraulic applications.

Our 27SiMn and 45# quenched & tempered steel tubes are engineered for extreme conditions—capable of withstanding pressures exceeding 45MPa and operating reliably in high-temperature environments up to 150°C.  Whether it’s a standard component or a mission-critical hydraulic cylinder, Carridea’s tubes deliver consistent, failure-resistant performance.

Fully Customizable to Meet Your Exact Needs

At Carridea, we understand that industrial applications are never one-size-fits-all.  That’s why we offer comprehensive customization services tailored to your unique specifications.  From non-standard dimensions (including lengths up to 12 meters) to specialized materials such as 20#, 45#, 16Mn, 27SiMn, and 42CrMo, we adapt our production to your requirements.

Our value-added processing capabilities include stress-relief annealing, precision straightening, cutting, welding, and deep-hole roller burnishing—ensuring your tubes are not just delivered, but fully engineered for seamless integration.  With a minimum order quantity of just 200kg, we support both large-scale production and small-batch prototyping or urgent repairs.

Compliance You Can Trust

Quality and compliance are embedded in our DNA.  Carridea adheres to the strictest international standards, backed by ISO9001 Quality Management, ISO14001 Environmental Management, and SGS certification.  Our in-house quality lab employs advanced inspection tools—including inner-hole straightness gauges and coordinate measuring machines—across over 30 meticulous inspection steps, from raw material intake to final shipment.  This rigorous process ensures a product yield rate of 99.9%, giving our clients confidence in every delivery.

We are proud to be recognized as a  "Contract-Compliant & Creditworthy Enterprise"  , reflecting our commitment to integrity and excellence.

Proven in Real-World Applications

Our tubes are tested not just in the lab, but in the field.  In mining hydraulic supports, our 27SiMn honing tubes have extended maintenance cycles from 1 to 3 months.  In metallurgical continuous casting, our precision tubes have reduced cutting errors to 0.3mm, meeting high-grade steel production standards.  And in emergency equipment repairs, our custom 16Mn honing tube sleeves have cut downtime by 70% and costs by 60%.

With 10000㎡ of warehouse space and over 1,000 product specifications in stock, we offer fast delivery—often within 24 hours—while our technical team ensures custom orders are prototyped and delivered swiftly.
