Slip On Flange
Slip On Flange
Slip on flange is a type of steel flange which slides over the end of steel piping and then welded in place.Because the pipe slips into the flange before welding,it has a low hub.The inside and outside of the flange are both welded,resulting in sufficient strengh and no leak. HAIHAO group slip on flanges can be easily fitted and welded into different pipes.It is perfect for lower pressure applications. (Know more about the Slip On Flange)
