Doubts about the connection of plastic pipe and steel pipe flange
Plastic pipe flanged fittings such as PPR, to have the corresponding, the flange pipe diameter, as long as the nominal nominal pressure and nominal diameter, nominal pressure pipe, bolt holes can be matched. Because the outer diameter of the pipe has been considered in the pipe fittings, there is no need to worry.
We have done such a job, generally can not match the diameter of the flange, just like the 110PPR pipe flange, and if the pipe flange connection, then use 150 of the flange, and then in the variable diameter to connect the steel pipe.
Pipe diameter is GB, such as DN100, DN150 and so on, the path is the sameBut the pipe will vary with the material used and the thickness of the materialBut the flange is the samePlastic pipes are the same size as flanges used in steel pipesWhen you refer to the piping design manual and the hardware manual on the plumbing and flanges, you'll see
