WHY CHOOSE US 

Wide size range, overlength without orbital welding

Our control line diameters range from 3.18mm (0.125’’) to 38.1 mm(1 1/2’’), and we can provide welded coiled tubing up to 10000 meters in length without butt welds.

Strict Stress Testing

All welded coiled tubing have passed 100% high-pressure testing, with a conventional testing pressure of 5000PSI,and a maximum of 15000PSI. (Note: The standard test pressure for seamless pipes is 7MPa, and our welded coiled tubing test pressure is much higher than the seamless pipe pressure test standard)

Fast Delivery Time

 
We have regular grade and sizes of welded coiled tubing in stock all year round, which can quickly respond to customers' urgent needs and ensure timely delivery.
