摘要： The clad material 12 is determined with respect to the thickness at both ends C in the length direction of the clad steel pipe 10, that is, the thickness at both ends in the length direction to be welded parts when welding laid clad steel pipes 10 in the construction field, so that the thickness has a value D which enables to absorb discrepancy with another clad steel pipe 10 when welding the laid clad steel pipe 10. The clad material 12 is further determined with respect to the thickness of the part E other than both ends C, so that the thickness has values F smaller than the predetermined value D.
