Product Introduction

Each one tubing coil is a completely continuous length without orbital welds.

Each one tubing coil is hydrostatic tested with a targeted pressure.

The test can be witnessed on site by the third party inspectors (SGS, BV, DNV).

Other tests are eddy current test, chemicals, flattening, flaring, tensile, yield, elongation, hardness for the material quality.

Meilong Tube offers coiled tubing in a wide range of corrosion resistant stainless steels, nickel alloys. We have extensive experience in product supply and innovation in this sector, from the technological advances required for subsea developments in the 1999 to the deepwater challenges of today.
