发明名称 METALLIC PIPE AND CABLE FORMED BY USING THE SAME
摘要 PURPOSE: To provide a metallic pipe with which pipe forming having high quality is executable even without washing. CONSTITUTION: This metallic pipe is formed by rounding a metallic strip 11 by a forming tool and subjecting the butt parts to TIG welding. This metallic strip 11 is formed by successively coating the front surface of a base metal 12 with a metallic chromium layer 13, a metallic tin layer 1 and a chromium oxide layer 15. The front surface 16 of the chromium oxide layer 15 is roughened to surface roughness 0.6 to 1.5μm by which the flawing of the front surface 16 at the time of pipe making is prevented.
