Abstract
A method of using a mechanical joint restraint includes inserting an end of a pipe length into a gland bore of a gland, a ring bore of a gripping ring, and a gasket bore of a gasket, the gland, the gripping ring, and the gasket together forming the mechanical joint restraint; inserting at least a portion of the gasket of the mechanical joint restraint into a socket of a piping element; inserting the end of the pipe length into the socket of the piping element; and drawing the gland towards a flange of the piping element to compress the gasket into sealing engagement with the piping element and the pipe length.
Claims22
A method of using a mechanical joint restraint, the method comprising:
- inserting an end of a pipe length into a gland bore of a gland, a ring bore of a gripping ring, and a gasket bore of a gasket, the gland, the gripping ring, and the gasket together forming the mechanical joint restraint, wherein:
- inserting the end of the pipe length into the socket of the piping element comprises contacting a stop lip of the gasket with the end of the pipe length, the stop lip extending radially inward from a pipe collar extending axially inward from a sealing band of the gasket with respect to an axis of the gasket, the stop lip defining a lip height;
- and
- the gasket further comprises a second stop lip extending radially outward from a remaining portion of the gasket with respect to an axis defined by the gasket bore of the gasket, the second stop lip defining a second lip height;
- inserting at least a portion of the gasket of the mechanical joint restraint into a socket of a piping element;
- inserting the end of the pipe length into the socket of the piping element;
- and
- drawing the gland towards a flange of the piping element to compress the gasket into sealing engagement with the piping element and the pipe length.
A method of using a mechanical joint restraint, the method comprising:
- inserting an end of a pipe length into a gland bore of a gland, a ring bore of a gripping ring, and a gasket bore of a one-piece elastic gasket, the gland, the gripping ring, and the gasket together forming the mechanical joint restraint, wherein inserting the end of the pipe length into the socket of the piping element comprises contacting a stop lip of the gasket with the end of the pipe length, the stop lip extending radially inward from a pipe collar extending axially inward from a sealing band of the gasket with respect to an axis of the gasket, the stop lip defining a lip height;
- inserting at least a portion of the gasket of the mechanical joint restraint into a socket of a piping element;
- inserting the end of the pipe length into the socket of the piping element;
- and
- drawing the gland towards a flange of the piping element to compress the gasket into sealing engagement with the piping element and the pipe length.
