摘要： Disclosed are systems and methods for manufacturing compression collars for reinforcing sealed connections between a length of piping and a plumbing fitting. Specifically, compression collars and related methods of making include extruding a hollow tube having one or more ridges which are then partially removed or trimmed to provide positioning tabs on one end of the compression collar. The compression collars can be cut to the desired length from the extruded hollow tube. In this way, compression collars with features for enhancing the strength and reliability of an interference fit, as well as their ease of use, can be manufactured rapidly with little material waste through modifications to the extrusion process.

摘要： A pipe joining system and pipe joint are shown m which two sections of molecularly oriented pipe are joined using heat shrinking techniques. A first section of pipe is provided having a straight, pre-formed socket with an internal diameter and with an end opening having enough clearance to allow a mating spigot section having a given external diameter to be inserted into the socket end opening. After the spigot end is inserted to a given depth, the socket is heated sufficiently so that the internal diameter of the socket end comes into contact with the external diameter of the spigot end, the molecularly oriented pipe being in a rubbery state and exhibiting a low elastic modulus which allows the socket end to conform tightly to the spigot end external diameter without deforming the spigot end.

摘要： A pipe has a tubular body with a male end and a female end. The male end has an external surface with a first engagement groove. The female end has an internal surface with a second engagement groove, and an aperture extending from an outer surface of the tubular body to the second engagement groove. The female end receives the male end of another pipe such that the first engagement groove of the male end axially aligns with the second engagement groove of the female end to establish a spline engagement groove having a groove length, LG. A flexible spline is located in the spline engagement groove to lock the pipes together and establish a pipe assembly. The flexible spline has a spline length, LS, and LS≦LG.

摘要： A backup ring for a pipe joint restraint includes a continuous one piece ring member or opposed ring segments, both including multiple inside radii to provide a portion of the ring which may be secured to a pipe fitting and a portion of the ring which is adapted to provide clearance for reinforced areas of a pipe fitting, such as a fillet reinforcement at a branch portion of a tee fitting. The ring embodiments with multiple ring segments include opposed radially projecting ears with fastener receiving bores and radially projecting lugs adapted to provide for connecting the ring assembly to a second ring assembly or gland clamped to the pipe section which is to be restrained in connection with the pipe fitting to which the backup ring assembly is clamped. The circumferential extent of the ring segments is preferably less than 180.degree. to accommodate a range of pipe fitting diameters with a single size ring segment.

摘要： A hard outer member generally centered on an axis and having a concave inner surface is injection molded of a relatively hard synthetic resin to have on its inner surface at one end a recess formed with a radially throughgoing passage. Parts of the mold in which this member is molded are then displaced before the resin has time to cure and another softer synthetic resin injected through this radially throughgoing passage to form in the recess a relatively soft seal having a sprue extending through the passage. The seal therefore adheres in surface contact with the inner surface at the recess and the sprue further ensures excellent holding of the seal on the member.
