    Abstract: Pipes (40) of a predetermined length are filled with a nitrogen gas (4a). Cross-sectionally hat-shaped plugs (50) comprising a brazing filler metal are press fitted in open ends of joint portions (42, 42) at both ends of the pipes (40) so as to seal the pipes (40), whereby the plugs (50) are fixed to the joint portions (42, 42). One side portion of a connecting piece (60) is then inserted into the joint portion (42) of one pipe (40) by breaking the relative plug (50) thereby, while the other side portion of the connecting piece (60) is inserted into the joint portion (42) of the other pipe (40) by breaking the relative plug (50) thereby. The plugs (50) are then melted to braze the joint portions (42) of the pipes (40) and the connecting piece (60) to each other.

    Abstract translation: 用氮气(4a)填充预定长度的管道(40)。 包括钎料的横截面帽形塞(50)在管(40)的两端压接在接合部(42,42)的开口端,以密封管(40),由此 插头(50)固定在接头部分(42,42)上。 然后,连接件(60)的另一侧部分插入连接件(60)的一侧部分,通过断开相关塞(50)而插入到一个管(40)的接合部分(42) 通过断开相关插头(50)而进入另一个管道(40)的接合部分(42)。 然后将塞子(50)熔化以将管道(40)的连接部分(42)和连接件(60)彼此钎焊。
