(OP)
Hi All,

Please find attached Photo,

I was passing by other site and i fouud this layout in the trench. It seems to me that, Steel pipe push in to DR 18 C900. Does it possible by using certain product?

 

RE: underground pipe

It appears that it is physically possible to push steel pipe (assuming white pipe is the steel) into C900 PVC (assuming blue pipe is PVC).  That being said, I am not aware of any products that will seal the layout shown in the picture.  The steel appears to be pushed inside the spigot end of the PVC and not into a bell, which would contain a gasket.  There are products that can be used to join different pipe materials, with different ODs,at the spigot ends that do not require one to be inserted into another.  These products are commonly called "Dresser Couplings".  Many manufacturers make products that will work for this.
