Abstract
A connecting piece for establishing a connecting arrangement for a pipe which can be pressed together comprises a stub which can be inserted into a pipe. Profilings for the pressing-together with the pipe and a stop are on the stub. At least one radially projecting spacer is provided on the stub. The spacer defining a gap for forming a flow duct between the stub and the pipe. The spacer may have an interruption for forming part of the flow duct.
Claims11
A connecting piece, for establishing a connecting arrangement for a pipe, when pressed together the piece comprising:
- a stub which can be inserted into a pipe;
- profilings on the stub for the pressing-together with the pipe;
- a stop on the stub for the pipe;
- at least one radially protecting spacer on the stub, the spacer defining a gap forming a flow duct between the stub and the pipe to permit fluid to flow to the outside to provide an indication of a leak;
- and
- a pressable section on the stub including the profilings which are circular at the outer circumference.
A connecting piece, for establishing a connecting arrangement for a pipe, when pressed together, the piece comprising:
- a stub which can be inserted into a pipe;
- profilings on the stub for the pressing-together with the pipe;
- a stop on the stub for the pipe;
- at least one radially projecting spacer on the stub, the spacer defining a gap forming a flow duct between the stub and the pipe;
- and
- including a recess on the stop forming a portion of the flow duct between the face of the pipe and the stop.
A connecting piece for establishing a connecting arrangement for a pipe, when pressed together, the piece comprising:
- a stub which can be inserted into a pipe;
- profilings on the stub for the pressing-together with the pipe;
- a stop on the stub for the pipe;
- at least one radially projecting spacer on the stub, the spacer defining a gap forming a flow duct between the stub and the pipe;
- wherein the stub has, adjacent to the spacer, a pressable section which has an essentially ring-shaped cross-section and whose diameter is slightly reduced with respect to the spacer;
- and
- wherein the pressable section includes the profilings which are circular at the outer circumference.
A connecting piece for establishing a connecting arrangement for a pipe, when pressed together the piece comprising:
