摘要： PURPOSE:To intrude a joining part into the other steel pipe while reducing radially the joining part to join them tightly to each other without causing an electric potential corrosion, by inserting the joining part, formed by expanding the end part of a stainless steel pipe, into the same stainless steel pipe, and fitting a shrinkage ring to the outer circumference of the joining part. CONSTITUTION:A joint 2 is formed by expanding the end part of a stainless steel pipe similar to a stainless steel pipe 1, into a cylindrical shape having an inner diameter 0.05-0.35mm. larger than a maximum diameter obtained in consideration of a tolerance of the stainless steel pipe 1. Further, a shrinkage ring 3 consists of a material having the same yielding point or 0.2% offset yield strength of the pipe 1 or larger ones; the outer diameter D and width W of the ring 3 are 1.25-1.6 and 0.35-0.7 times the outer diameter (d) of the pipe 1, and the inner diameter (d') of the cylindrical part 3c is 0.92-0.98 times the sum (d+2t), where (d) is the outer diameter of the pipe 1 and (t) is the wall thickness of the expanded part of the joint 2; further, the width W of the cylindrical part 3c is 0.03-0.32 times the outer diameter (d) of the pipe 1.
摘要翻译：目的：通过将不锈钢管的端部扩大而形成的接合部插入，将接合部插入到另一个钢管中，同时径向减小接合部彼此紧密地彼此连接而不引起电位腐蚀，插入相同的不锈钢管中，并且在接合部的外周配合收缩环。构成：通过将类似于不锈钢管1的不锈钢管的端部膨胀成内径为0.05-0.35mm的圆筒形形成接头2。大于考虑到不锈钢管1的公差所获得的最大直径。此外，收缩环3由具有相同屈服点或管1的偏心屈服强度的偏离屈服强度的材料1或更大的材料构成。环3的外径D和宽度W为管1的外径（d）的1.25-1.6和0.35-0.7倍，圆筒部3c的内径（d'）为0.92-0.98倍和（d + 2t），其中（d）是管1的外径，（t）是接头2的膨胀部分的壁厚; 此外，圆筒部3c的宽度W为管1的外径（d）的0.03〜0.32倍。

摘要： PURPOSE: To touch up the surface of a plated steel by a thermally sprayed layer excellent in corrosion resistance and having sufficient thickness. CONSTITUTION: At the time of touching-up a Zn or Zn-Al alloy plated layer formed on a plated steel 1, the part of the plated layer to be touched up is thermal-sprayed with Al, and next, it is thermal-sprayed with a Zn or Zn-Al alloy. A bead 7 on the surface of a welded steel tube 3 produced from the plated steel sheet 1 is machined. After that, an Al thermally sprayed layer is formed by a thermal spraying gun 10, and next, a Zn or Zn-Al alloy touch-up layer is formed by a thermal spraying gun 11. Since the touch-up layer excellent in corrosion resistance is formed, the part in which the plated layer is damaged by bead cutting, press forming or the like is not formed into a starting point of the generation of corrosion.
