Steel pipe excellent in formability and method for producing thereof

A steel pipe excellent in formability characterized in that the texture of the steel pipe satisfies one or more of the following conditions {circle over (1)} to {circle over (3)}.

• {circle over (1)} at least one or more of the following ratios being 3.0 or more:
• the ratio of the X-ray strength in the orientation component of {111}<110> to random X-ray diffraction strength on a plane at the wall thickness center;
• the average for the ratios of the X-ray strength in the orientation component group of {110}<110> to {332}<110> to random X-ray diffraction strength on a plane at the wall thickness center;
• and the ratio of the X-ray strength in the orientation component of {110}<110> to random X-ray diffraction strength on a plane at the wall thickness center,
• {circle over (2)} at least either one or both of the following ratios being 3.0 or less:
• the average for the ratios of the X-ray strength in the orientation component group of {100}<110> to {223}<110> to random X-ray diffraction strength on a plane at the wall thickness center;
• and the ratio of the X-ray strength in the orientation component of {100}<110> to random X-ray diffraction strength on a plane at the wall thickness center, and
• {circle over (3)} at least either one or both of the following conditions being satisfied:
• the average for the ratios of the X-ray strength in the orientation component group of {111}<110> to {111}<112> and {554}<225> to random X-ray diffraction strength on a plane at the wall thickness center being 2.0 or more;
• and the ratio of the X-ray strength in the orientation component of {111}<110> to random X-ray diffraction strength on a plane at the wall thickness center being 3.0 or more.
