Seamless & Welded Tubing
How To order
Product & Size Ranges Seamless tubes in straight length, precision cut or coils. 1/8"~1-1/4" OD, 6mm~28mmOD. Welded or semi-seamless (welded, drawn and bead reduced) tubes in straight length, precisio cut or coils. 1/8"~2" OD, 6mm~50mmOD.
Materials of Construction Grade Inside Surface Roughness
Features - Quality mother pipes as raw materials. - Excellent finished inner and outer sur face by precision cold drawn. - Strict size tolerance control in accordance with ASTM standards. - Fully bright annealed for outstanding corrosion resistance for both seamless and welded tubing. - Exact hardness for proper tubing. - ECT (Eddy Current Test) for every piece of tubing - Guaranteed application for all UNILOK tube fittings and valves with UNILOK ports.
