1.前言目前,铝焊接管的用途,主要是电视天线管,以桌子、椅子的结构架为代表的家俱用管,装饰用管等,其合金是1000系、5000系两类,尺寸范围主要是外径为12.5～30毫米,壁厚为0.5～2.5毫米.关于这方面因过去其他公司已经有过介绍,因此,在此本公司仅就制造用于热交换器的壁厚为0.25～4.0毫米、外径为5.0～16.0毫米的薄壁铝焊接管的实际操作应注意的要点介绍如下.
1. Preface Currently, the use of aluminum welded pipe, mainly TV antenna tube to the table, chairs, structural frame represented by the furniture, decorative tubes, etc., the alloy is 1000 series, 5000 series of two types, the size range of the main Is the outer diameter of 12.5 to 30 mm, the wall thickness of 0.5 to 2.5 mm. In this regard because other companies have been introduced in the past, therefore, in this company only for the manufacture of heat exchanger wall thickness of 0.25 to 4.0 Mm, outer diameter of 5.0 to 16.0 mm Thin-walled aluminum welded pipe The actual operation should be noted that the points are as follows.
