Coiled tubing are long, continuous lengths of tubing that are wound onto a spool or drum in a tightly coiled configuration, without the need for coupling or joining multiple shorter lengths. This can reduce installation time and minimize potential leak points. Coiled tubes take up less storage space compared to straight lengths of tubing. The compact coiled design allows for efficient transportation, storage, and handling, particularly in situations where space is limited.

| Specification | Outer diameter | 3/16" - 1 1/4" (4.76-31.8mm) |
| Wall thickness | 0.028"-0.083" (0.7mm-2.11mm) |
|
| Length | 1:According to the different outer diameter and wall thickness, the weight of one coil of seamless coiled tubes is about 80kg-100kg. 2:Please Note:The longer the length of seamless coiled tubes, the more expensive the price Is. The most economical price is that the weight of single coil is less than 28kg. 3:According to the required outer diameter and wall thickness, the length of stainless steel seamless coiled tubes is converted by the theoretical calculation formula of stainless steel tube. 4:Solemnly Note:There is no welding point in the whole coils of seamless coiled tubes. 5:According to the demand, multi coils stainless steel seamless coiled tubes can also be used to form super long stainless steel coil tubes of several thousand meters by butt welding. |
