Formwork Plastic Tube and Cone are used in Tie rod protecting pipe . The end is Plastic Cup or Plastic Cone. And the plastic tube with two pieces of the plastic cone on the both sides also called Plastic Sleeve. It is used to protect the Tie Rod and there are some different sizes and thickness available.
While making a RCC Structure, Tie-rod costs a lot and during placing of shutters and cements concrete, some of the Tie-rods get stuck inside the PVC Pipe (which acts as a cover to Tie-rod).
This happens due to the fact that PVC pipes are cut by the labour, which is not accurate resulting in a lot of cement concrete flow inside the pipe through corners which finally cause the above mentioned problem
