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.
Claims14
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 until an inwardly extending front face of a piping shield of the piping connector extends over, contacts, and covers the abutment end of the first piece of pipe;
- inserting a spool piece into an opening defined by the piping shield and into the abutment end of the first of pipe until an outwardly extending shoulder of the spool piece contacts the piping shield;
- and
- crimping the piping connector to deform the piping around the spool piece,
- wherein the piping connector has a ring connector configured to fit around an external diameter of a pipe and the piping shield has at least one observation window cut into the piping shield adjacent to the front face of the piping shield and at a location at which a connection is made between the piping connector and the piping shield.

- inserting a spool piece into an opening defined by the piping shield and into the abutment end of the first piece of pipe until an outwardly extending shoulder of the spool piece contacts the piping shield;
- and
- crimping the piping connector to deform the piping around the spool piece,
- wherein the piping connector includes a ring connector having a cylindrical body defining an internal diameter for fitting around an external diameter of the first piece of pipe, a first circumferential groove is defined by an external surface of the cylindrical body of the ring connector, the first circumferential groove is laterally disposed between a first step and a second step that orthogonally extend from the first circumferential groove, the first step extends from a first end of the ring connector to the first circumferential groove and has an outer diameter that is greater than an outer diameter of the first circumferential groove, and the second step has an outer diameter that is greater than the first step;
- and
- wherein the piping shield has a cylindrical body defining at least one observation window cut into the shield adjacent to the front face of the piping shield and at a location at which a connection is made between the piping connector and the piping shield, the piping shield defining a second circumferential groove around an interior surface, the second circumferential groove of the piping shield disposed between a posterior end of the piping shield having an inner diameter that is smaller than an inner diameter of the second circumferential groove of the piping shield and an abutment having an inner diameter that is smaller than the inner diameter of the posterior end, wherein the connection is formed when the first step of the ring connector is disposed within the second circumferential groove defined by the piping shield and when the posterior end of the piping shield is received within the first circumferential groove defined by the ring connector.
