Abstract
Half-shell for the receiving and concentric guidance of a plastic pipe in a butt welding machine, wherein the half-shell has a semi-circular shape with an internal diameter corresponding to the external diameter of the pipe to be received, at least one external diameter in order to be accurately received in a clamping unit of a butt welding machine, a front face, a rear face and a thickness extending axially between the front face and the rear face, wherein at least one spacing element is arranged on the front face and protrudes over the front face in the axial direction.
Claims13
A half shell for receiving and concentric guidance of a plastic pipe in a butt welding machine, comprising wherein the half-shell has a semi-circular shape with an internal diameter configured to be corresponding to an external diameter of the pipe to be received, at least one external diameter in order to be accurately received in a clamping unit of a butt welding machine, a front face, a rear face and a thickness extending axially between the front face and the rear face, wherein at least one spacing element is arranged on the front face and protrudes over the front face in the axial direction;
- and
- wherein an axial stop shoulder is arranged on the half-shell for the axial positioning and fixing of the half-shell in a clamping unit of a butt welding machine.
A half shell for receiving and concentric guidance of a plastic pipe in a butt welding machine, comprising wherein the half-shell has a semi-circular shape with an internal diameter configured to be corresponding to an external diameter of the pipe to be received, at least one external diameter in order to be accurately received in a clamping unit of a butt welding machine, a front face, a rear face and a thickness extending axially between the front face and the rear face, wherein at least one spacing element is arranged on the front face and protrudes over the front face in the axial direction;
- and
- wherein the at least one spacing element protrudes radially over the external diameter.
A half shell for receiving and concentric guidance of a plastic pipe in a butt welding machine, comprising wherein the half-shell has a semi-circular shape with an internal diameter configured to be corresponding to an external diameter of the pipe to be received, at least one external diameter in order to be accurately received in a clamping unit of a butt welding machine, a front face, a rear face and a thickness extending axially between the front face and the rear face, wherein at least one spacing element is arranged on the front face and protrudes over the front face in the axial direction;
- and
- wherein the half-shell has a coding serving to identify the half-shell by a butt welding machine.
