Specifications & Applications

Stainless Steel Capillary Tubing, also called round tubing, can be supplied as a roll of coiled tubing thousands of meters long. This coiled tubing equipment can replace conventional tubing for many applications, offering features such as operation under belt pressure, continuous workflow, compact equipment size, fast operating cycles, and low costs. Continuous tubing plays an increasingly important role in oil and gas field repair, drilling, completion, logging, and other operations.

At least 30-50cm of pipe ends can be left for chemical fulfillment when required. The Capillary tubings are used in various critical applications with an inner surface free from oil, grease, and dust particles. These small-sized precision tubes' tolerances and thicknesses are fully customizable per client requirements.
