RESIN COATED STEEL PIPE, COATING MEMBER AT CONNECTION PART OF RESIN COATED STEEL PIPE AND COATING STRUCTURE AT CONNECTION PART OF RESIN COATED STEEL PIPE |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a corrosion-resistant resin coated steel pipe, a coating member at a connection part of the resin coated steel pipe and a coating structure at the connection part of the resin coated steel pipe capable of increasing joining strength of a joining part of a corrosion-resistant layer and the coating member of the resin coated steel pipe in coating the connection part of the resin coated steel pipe. <P>SOLUTION: An embodiment of this invention is the resin coated steel pipe having an outer circumference of the steel pipe coated by corrosion-resistant layer containing resin as main body. The resin coated steel pipe includes laser absorption part absorbing 70% or more laser of neighborhood of 940 nm wave length on an outer circumference surface. "Neighborhood" here is defined as a range of ±3% of 940 nm as center wave length. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
