Product introduction

Tube specially manufactures seamless and redrawn, welded and redrawn coiled tubing which are made from corrosion-resistant austenitic, duplex, super duplex stainless steels and nickel alloy grades. The tubing is used as hydraulic control lines and chemical injection lines specially serving oil and gas, geothermal industry.

Important

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.
