Frequently Asked Questions

1. What are the key benefits of using stainless steel coiled tubes?

Stainless steel coiled tubes offer excellent corrosion resistance, high pressure tolerance, and clean internal surfaces. Their continuous length reduces the need for multiple fittings and joints, significantly lowering the risk of system leaks.

2. Why is Eddy Current Testing (ECT) necessary for these tubes?

Eddy Current Testing is a non-destructive testing (NDT) method used to scan the tubing for surface and sub-surface imperfections, wall thickness variations, or cracks. It ensures the integrity and reliability of the tubing before deployment in critical applications.

3. In which industries are stainless steel coiled tubes commonly applied?

They are widely utilized in oil and gas, chemical processing, shipbuilding, aerospace, geothermal applications, and instrumentation systems, particularly for heat exchangers, hydraulic lines, and fluid control systems.

4. Can coiled tubes handle high-temperature and high-pressure environments?

Yes, depending on the material grade (such as 316L, 304, or duplex steel) and the wall thickness, coiled tubing is engineered to safely operate under elevated temperatures and extreme operating pressures.

5. What documentation is provided to guarantee product quality?

Every shipment is backed by comprehensive test reports, which include material certification, chemical analysis reports, dimensional checks, hydrostatic testing results, and eddy current test reports.
