钢带螺旋波纹管的连接一般采用扩口式接口与内胀式接口机械连接以及双热熔接口连接。
1.扩口式接口结构
扩口式接口PE管的用途，是以可锻铸铁或者球墨铸铁为主体材质，是由内衬管件体(衬套)、螺帽或者螺栓、螺纹环或者扩口压兰、密封胶圈组成，采用紧固螺帽或者压兰的方式使管材收缩，达到管材内表面和内衬管件体上密封胶圈形成斜侧密封连接的金属管件连接。
钢塑复合管
2.内胀式接口机械连接是以可锻铸铁或者球墨铸铁为主体材质，由管件体、螺帽或螺栓、胀口压兰或者胀口螺纹环、胀口卡环、密封胶圈组成，将管材扩胀与胀口压兰或者胀口螺纹环、胀口卡环形成一体，采用紧固螺帽或者压兰的方式使管材压缩端面密封胶圈，达到管材端面与管材端面或者管材端面与管件端面形成密封连 接的金属管件。
钢塑复合压力管
3.双热熔接口结构
双热熔接口连接是将钢塑管内外塑层及管件体承、插口面分别和加热板接触熔融后，将钢塑管插入管件体，进而使熔融的表面压接在一起，聚合物分子在热及压力的作用下运动，相互穿插盘绕，产生范德华作用力，冷却后形成焊接面的连接方式。
