ANSI/ASME B16.5 class 150 lap joint flange
Haihao Group manufacture and export ANSI/ASME B16.5 lap joint flange in various size,pressure and materials.Lap joint flange(loose flange) consists of backing flange and stud end,the stub end butt welding to the pipe,and the lap joint flange will be slip around the stub end.The lap flange is not connected with the pipe and the stub end directly,so it can be rotated,it is convenient to install the flange connection if there is some misalignment between the bolt holes.
