Abstract

A method to connect piping and a piping connection, having the features of a ring connector configured to snugly fit around an external diameter of a pipe; and a piping shield connected to the ring connector, the piping shield having at least one observation window cut into the shield, wherein the piping shield covers an abutment end of the pipe to be connected, wherein a joint between the ring connector and the piping shield forms a connection.

Claims

1. A piping connector, comprising:

a ring connector configured to snugly fit around an external diameter of a pipe; and

a piping shield connected to the ring connector, the piping shield having at least one observation window cut into the shield, wherein the piping shield covers an abutment end of the pipe to be connected, wherein a joint between the ring connector and the piping shield forms a connection.

2. The piping connector according to claim 1, wherein the connection formed between the piping shield and the ring connector is a groove arrangement.

3. The piping connector according to claim 1, wherein the piping shield is made of plastic.

4. The piping connector according to claim 1, wherein a number of the observation windows is two.

5. The piping connector according to claim 1, wherein the ring connector is made of stainless steel material.

6. The piping connector according to claim 1, wherein the ring connector is made of copper.

7. The piping connector according to claim 1, wherein the piping shield has a front face that extends over the abutment end of the pipe.

8. The piping connector according to claim 1, wherein the groove arrangement further comprises:

a first step, a depression and a second step on the ring connector, and

a ring abutment end, a shield groove and a posterior end on the pipe shield.

9. A method to connect at least two pieces of pipe, comprising:

placing a piping connector over an abutment end of a first piece of pipe;

inserting a spool piece into the abutment end; and

crimping the piping connector to deform the piping around the spool piece, wherein the piping connector has a ring connector configured to snugly fit around an external diameter of a pipe; and

a piping shield connected to the ring connector, the piping shield having at least one observation window cut into the shield, wherein the piping shield covers the abutment end of the pipe to be connected, wherein a joint between the ring connector and the piping shield forms a connection.

10. The method according to claim 9, wherein the connection between the piping shield and the ring connector is a groove arrangement.

11. The method according to claim 9, wherein the piping shield is made of plastic.

12. The method according to claim 9, wherein a number of the observation windows is two.

13. The method according to claim 9, wherein the ring connector is made of stainless steel material.

14. The method according to claim 9, wherein the ring connector is made of copper.

15. The method according to claim 9, wherein the piping shield has a front face that extends over the abutment end of the pipe.

16. The piping connector according to claim 9, wherein the groove arrangement further comprises:

a first step, a depression and a second step on the ring connector, and

a ring abutment end, a shield groove and a posterior end on the pipe shield.

17. The method according to claim 9, wherein the spool piece has a ridged surface.
