Coiled Tubing

Coiled Tubing Description

Huashang seamless coiled tubing we produce can reach more than 1000 meters, compared with other coiled tubing manufacturers, which particularly reduces the tubing unions and connection for the duration of the installation, making the set up extra convenient, highly reduces the complete cost in installation, and additionally the maintenance cost.

If you choose to reduce the risk of leaks in the instrument of the hydraulic system. The concentric coiled tubing will be your first and excellent choice. Especially for the scenario of vertical installation. As you limit the tubing unions and connections, it totally improves the integrity of the total system, improves the protection and safety.

As a stainless steel tubing manufacturer, we all recognize well that due to the fact of the constrained coiled tubing sizes of container in sea shipment, normally, we only can ship seamless tube with size no longer more than 15 meters, but for coiled tubing, even size accomplishing extra than a thousand meters, it additionally can be shipped easily in container, the seamless coiled tubing is level wound per coil, then packed by plywood case, also it can be level wound on timber or plastic spools for the smaller dimensions.

Coiled Tubing Advantage

1.Seamless and welded
2.Bright annealling
3.Super Long≧1000meters

Coiled Tubing Sizes

The welded coil tubing sizes:
OD: 0.19mm---25.4mm
T.W: 0.02mm--2.11mm
