不锈钢金属软管（又称，金属波纹管、不锈钢软管、不锈钢波纹软管）是现代工业管路中的一种高品质的柔性管道。它主要由不锈钢波纹管、不锈钢网套和金属软管接头组成。
Stainless steel metal hose (also known as metal corrugated pipe, stainless steel hose, stainless steel corrugated hose) is a high-quality flexible pipe in modern industrial pipeline. It is mainly composed of stainless steel bellows, stainless steel mesh sleeve and metal hose joint.
不锈钢软管使用的波纹管有两种，一种是螺旋形波纹管；另一种是环形波纹管。
There are two kinds of bellows used in stainless steel hose, one is spiral bellows, the other is annular bellows.
（1）螺旋形金属软管是波纹呈螺旋状排布的管形壳体，在相邻的两波纹之间有一个螺旋升角，所有的波纹都可通过一条螺旋线连接起来。
(1) spiral metal hose is a pipe shell with spiral arrangement of corrugations. There is a helix rising angle between two adjacent corrugations. All corrugations can be connected by a helix.
（2）环形金属软管是波纹呈闭合圆环状的管形壳体，波与波之间由圆环波纹串联而成。环形金属软管由无缝管材或焊接管材加工成形。受加工方式制约，较之螺旋形波纹管，其单管长度通常较短。环形金属软管的优点是弹性好、刚度小。
(2) the circular metal hose is a pipe shaped shell with closed circular corrugations. The waves are connected in series by circular corrugations. The circular metal hose is made of seamless pipe or welded pipe. The length of single pipe is usually shorter than that of spiral corrugated pipe due to the restriction of processing method. The advantages of circular metal hose are good elasticity and small rigidity.
