norms from Copper alloys
Please read below on the wished for trade-name in the left hand column, and get it translated into LM-language on the right-hand
column. The right hand column with our name is either identical in composition or a fully replaceable alloy with only minor differences.
The column in the middle states the norm and its country of origin.
With no marks in front of LM’s alloy = alloy is identical, with this sign “~” = alloy is very similar, fully replaceable.

铜管又称紫铜管是压制的和拉制的无缝管。
铜管重量较轻,导热性好,低温强度高。常用于制造换热设备(如冷凝器等)。也用于制氧设备中装配低温管路。直径小的铜管常用于输送有压力的液体(如润滑系统、油压系统等)和用作仪表的测压管等。
铜管是现代承包商在所有住宅商品房的自来水管道、供热、制冷管道安装的优选。
1、由于铜管容易加工和连接,使其在安装时,可以节省材料和总费用,具有很好的稳定性以及可靠性,可省去维修。
2、铜是轻便的。 对相同内径的绞螺纹管而言,铜管不需要黑色金属的厚度。当安装时,铜管的输送费用更小,维护更容 易,占用空间更小。
