Systems and methods for pipe boots

Abstract

In some embodiments, a pipe boot flange may include one or more fitting portions. The pipe boot flange may include one diaphragm gate. In some embodiments, a method may include injecting a flow of a resin through a runner and into a diaphragm gate of a mold cavity for a pipe boot flange. The method may include directing the resin through the mold cavity. The method may include forming the pipe boot flange. The method may include removing the formed pipe boot flange from the mold cavity.

What is claimed is: 
     
         1 . A pipe boot flange comprising:
 one or more fitting portions; and   one diaphragm gate.   
     
     
         2 . The pipe boot flange of  claim 1 , wherein the one or more fitting portions comprise a plurality of concentric fitting portions of different circumference, wherein adjacent fitting portions are separated by a boundary. 
     
     
         3 . The pipe boot flange of  claim 2 , wherein each of the boundaries are at a boundary angle of about 90 degrees relative to a vertical axis. 
     
     
         4 . The pipe boot flange of  claim 1 , wherein a wall of each of the one or more fitting portions are each disposed at a wall angle relative to a vertical axis. 
     
     
         5 . The pipe boot flange of  claim 4 , wherein the wall angle is about 1 to 3 degrees relative to the vertical axis. 
     
     
         6 . The pipe boot flange of  claim 1 , wherein the pipe boot flange is formed using an injection molding process. 
     
     
         7 . The pipe boot flange of  claim 6 , wherein the pipe boot flange is made of a thermoplastic elastomer material. 
     
     
         8 . The pipe boot flange of  claim 6 , wherein the pipe boot flange is formed as a unitary molded body without vertical weld lines formed therein. 
     
     
         9 . The pipe boot flange of  claim 1 , wherein each of the one or more fitting portions define a tab having a first portion and a second portion. 
     
     
         10 . The pipe boot flange of  claim 9 , wherein the tab of each of the one or more fitting portions protrudes from a wall of the respective fitting portion such that one of the first portion or the second portion is configured to flex and engage a pipe to form a seal against the pipe when the pipe boot flange is placed over the pipe. 
     
     
         11 . The pipe boot flange of  claim 1 , further comprising an attachment member defining one or more fastener towers. 
     
     
         12 . A pipe boot comprising:
 a flange extending between a first end and a second end, the flange defining a plurality of concentric fitting portions between the first end and the second end, each of the plurality of concentric fitting portions sized for a respective pipe size, the flange having one diaphragm gate connected to a first one of plurality of concentric fitting portions at the first end of the flange.   
     
     
         13 . The pipe boot of  claim 12 , wherein adjacent concentric fitting portions are separated by a boundary that is at a boundary angle of about 90 degrees relative to a vertical axis. 
     
     
         14 . The pipe boot of  claim 12 , wherein a wall of each of the plurality of concentric fitting portions are each disposed at a wall angle relative to a vertical axis. 
     
     
         15 . The pipe boot of  claim 14 , wherein the wall angle is about 1 to 3 degrees relative to the vertical axis. 
     
     
         16 . The pipe boot of  claim 12 , wherein the flange is formed using an injection molding process. 
     
     
         17 . The pipe boot of  claim 16 , wherein the flange is made of a thermoplastic elastomer material. 
     
     
         18 . The pipe boot  claim 16 , wherein the flange is formed as a unitary molded body without vertical weld lines formed therein. 
     
     
         19 . The pipe boot of  claim 12 , wherein each of the plurality of concentric fitting portions define a tab having a first portion and a second portion. 
     
     
         20 . The pipe boot of  claim 19 , wherein the tab of each of the plurality of concentric fitting portions protrudes from a wall of the respective fitting portion such that one of the first portion or the second portion is configured to flex and engage a pipe to form a seal against the pipe when the flange is placed over the pipe. 
     
     
         21 . The pipe boot of  claim 12 , wherein the flange further comprises an attachment member defining one or more fastener towers each sized and configured to receive a fastener. 
     
     
         22 . A method comprising:
 injecting a flow of a resin through a runner and into a diaphragm gate of a mold cavity for a pipe boot flange;   directing the resin through the mold cavity;   forming the pipe boot flange; and   removing the formed pipe boot flange from the mold cavity.   
     
     
         23 . The method of  claim 22 , wherein the resin is uniformly directed through the mold cavity circumferentially, whereby the formed pipe boot flange is formed as a unitary molded body without vertical weld lines formed therein. 
     
     
         24 . The method of  claim 22 , further comprising removing the diaphragm gate from the formed pipe boot flange.
