3/16" - 1 1/4"  (4.76-31.8mm)

Wall thickness :

0.028"-0.083" (0.7mm-2.11mm)

Length:

The weight of a single coil of stainless steel seamless coiled tubes ranges from 80 kg to 100 kg, depending on outer diameter and wall thickness. Longer seamless coiled tubes are more expensive, with the most cost-effective option being coils under 28 kg. The length of stainless steel seamless coiled tubes is calculated based on required dimensions using the theoretical weight formula. These coils have no weld points. Multiple coils can be butt-welded to create super-long tubes several thousand meters in length.

What is stainless steel coiled tubing?

Advantages of stainless steel coil tubing:

Stainless steel coiled tubing consists of long, continuous lengths of tubing that are wound tightly onto a spool or drum in a coiled configuration, eliminating the requirement for coupling or joining multiple shorter lengths. This approach can reduce installation time and minimize potential leak points. Coiled tubing occupies less storage space compared to straight lengths of tubing. The compact coiled design enables efficient transportation, storage, and handling, especially in scenarios where space is limited.

The traditional method of welding long stick tubing end - to - end or with fittings is a highly labor - intensive procedure. This welding process is time - consuming and costly. In contrast, using coil tubing not only requires a fraction of the time, thereby reducing labor costs, but also enables a much safer and maintenance - free installation. Additionally, coil tubing offers increased corrosion resistance due to the properties of stainless steel, duplex, and nickel alloys. It also provides improved reliability as using fewer mechanical fittings or welds reduces the likelihood of defects such as leaks and other long - term failures. Moreover, it leads to reduced installation labor costs as installing a continuous length of tube takes less time and is more reliable than coupling multiple shorter lengths.

Bright annealed  BA Stainless Steel Seamless Coild Tube Tubing

Among the various available diameters of stainless steel coiled tubing, 1/2 inch and 1 inch are the most commonly selected options.

Long-length coiled tubing offers significant advantages over alternative material forms, including:

- Reduced material waste and scrap  
- Lower labor costs  
- Excellent corrosion resistance  
- Minimal maintenance requirements  
- Cost-effective and efficient transportation  
- Fewer welds or mechanical fittings needed  

Furthermore, the installation of coiled stainless steel tubing is faster, safer, and more economical. Compared to joining multiple sections of rigid tubing through welding, a continuous length of seamless coiled tubing requires less time and labor to install. Enhanced system reliability and safety are additional benefits when sourcing coiled tubing from a leading supplier. Utilizing a single, uninterrupted tube eliminates potential leak points and reduces the risk of long-term system failures.

When sourcing stainless steel coiled tubing for manufacturing processes, ensure procurement from a trusted and experienced supplier. Based on your technical specifications, the supplier will recommend the appropriate gauge, diameter, and length to meet your operational needs.

Application of  Bright Annealed (BA) Stainless Steel Coil Tube / Tubing

Bright annealed (BA) stainless steel coil tubing is utilized in high - hygiene, high - purity, and aesthetic applications such as

- Transfer of gases and liquids for heating, cooling, and various industrial purposes  
- Medical equipment systems  
- Solar energy installations  
- Plumbing systems  
- Gas manifolds  
- Steam surface condensers  

This is because it has an exceptionally smooth, clean, and corrosion - resistant surface that prevents contamination and bacterial growth, rendering it ideal for fluid transfer in critical industries. Additionally, it is employed in heat exchangers, automotive, and oil and gas sectors owing to its durability and resistance under harsh conditions.
