Abstract
A pipe cleaning assembly has a connection fixture having a body defining a cavity. A first aperture, opposing first auxiliary aperture coaxially aligned with the first aperture, second aperture, and opposing second auxiliary aperture coaxially aligned with the second aperture are in fluid communication with the cavity. A first connection flange extends from and surrounds the first aperture, a second connection flange extends from and surrounds the second aperture, a third connection flange extends from and surrounds the first auxiliary aperture, and a fourth connection flange extends from and surrounds the second auxiliary aperture. A first valve is connected to the third connection flange to control fluid flow through the first auxiliary aperture.
Claims20
A pipe cleaning assembly, comprising:
- a connection fixture comprising a body defining a cavity, a first aperture in fluid communication with the cavity, a first connection flange extending from and surrounding the first aperture, an opposing first auxiliary aperture in fluid communication with the cavity and coaxially aligned with the first aperture, a third connection flange extending from and surrounding the first auxiliary aperture, a second aperture in fluid communication with the cavity, a second connection flange extending from and surrounding the second aperture, an opposing second auxiliary aperture in fluid communication with the cavity and coaxially aligned with the second aperture, and a fourth connection flange extending from and surrounding the second auxiliary aperture;
- and
- a first valve connected to the third connection flange of the connection fixture to control fluid flow through the first auxiliary aperture.
A pipe cleaning assembly, comprising:
- a connection fixture comprising a body defining a cavity, a first aperture in fluid communication with the cavity, a first connection flange extending from and surrounding the first aperture, an opposing first auxiliary aperture in fluid communication with the cavity and coaxially aligned with the first aperture, a third connection flange extending from and surrounding the first auxiliary aperture, a second aperture in fluid communication with the cavity, a second connection flange extending from and surrounding the second aperture, an opposing second auxiliary aperture in fluid communication with the cavity and coaxially aligned with the second aperture, and a fourth connection flange extending from and surrounding the second auxiliary aperture;
- and
- a diverter trim inserted through the second auxiliary aperture and positioned within the cavity of the body, the diverter trim including a wall that extends across the diverter trim and directs fluid flowing through the connection fixture.
A method of cleaning a piping system, comprising the steps of:
- installing a connection fixture between a first pipe section of the piping system and a second pipe section of the piping system, the connection fixture comprising a body defining a cavity, a first aperture in fluid communication with the cavity, a first connection flange extending from and surrounding the first aperture and configured to be secured to a flange of the first pipe section, an opposing first auxiliary aperture in fluid communication with the cavity and coaxially aligned with the first aperture, a second aperture in fluid communication with the cavity, a second connection flange extending from and surrounding the second aperture and configured to be secured to a flange of the second pipe section, and an opposing second auxiliary aperture in fluid communication with the cavity and coaxially aligned with the second aperture;
- flowing a pressurized fluid through piping system;
- removing the connection fixture;
- and
- installing a control valve between first pipe section and second pipe section.
