A tapping saddle for a plastic main pipe carrying a medium includes a stub having a central axis, a saddle piece, and a drill. The drill is configured to be moved axially in the stub. A heating element geometry, which is used for welding the tapping saddle to a main tube outer circumference, is arranged on an inside diameter of the saddle piece. The heating element geometry has a winding having an outer winding region and an inner winding region. In the inner winding region, the winding extends in meandering loops along a circle concentric with the central axis of the stub.

A liner assembly and method for lining a damaged pipe junction between a main and lateral pipe is provided. The liner assembly includes a main liner member and a lateral liner tube. A collar disposed near the juncture between the main liner member and lateral liner tube is impregnated with a liquid hydrophobic or hydrophilic material capable of curing in a flexible or rigid state with the material expanding in the presence of water. The hydrophobic or hydrophilic material can also be applied without the use of the collar. When the liner assembly is pressed against the main and lateral pipes, a portion of the hydrophilic or hydrophobic material is forced into the damaged pipe junction.

An overmolding method for forming joints in a fluid-flow apparatus utilizes a connector or fitting as a component for mold forming. The connector or fitting is not removed after the overmolding and thus forms part of the joint assembly.

The apparatus 10 includes a table 12 which defines a flat top surface 14. Two spaced apart, parallel tracks 16.1, 16.2 are mounted on top of the surface 14. A first positioning arrangement 18, is displaceably mounted on top of the tracks 16. When in use, a plurality 5 of collector tubes 300 can be arranged parallel to one another on top of the frame 24 such that they extend along a displacement path 400 of the tracks 16 and are substantially perpendicular to tubes 306 and 308.

A tubing including an overmold is connected to a fitting by welding the overmold to the fitting. Methods for doing the same are also provided. Also provided are methods for forming an overmold on a tubing or on a tubing and fitting assembly.

A snap fitting for use in plumbing is provided. The snap fitting includes a main body formed of plastic and shaped to extend partially around a cylindrical pipe to snap over the pipe and an inset for extending from an interior side of the main body into a hole in the cylindrical pipe.

A tubing including an overmold is connected to a fitting by welding the overmold to the fitting. Methods for doing the same are also provided. Also provided are methods for forming an overmold on a tubing or on a tubing and fitting assembly.

Induction Weldable Pipe Connectors (IWPCs) (400) for electromagnetic induction welding with at least one plastic pipe (30). IWPCs (400) include a tubular induction weldable mounting (401) having an opposite pair of induction weldable sockets (404A, 404B), a tubular cover (406) externally mounted on the induction weldable mounting (401), and a tubular pipe tang (407) internally disposed in one induction weldable socket (404A, 404B) for destining an induction weldable socket (404A, 404B) as an induction weldable pipe socket (408A, 408B) for forced sliding insertion of a pipe end (31) thereinto. The cover (406) includes an opposite pair of thermally insulated induction weldable socket mouth rims (426A, 426B) for entrapping melted solder lining (412) inside the induction weldable mounting (401) during an electromagnetic induction welding operation, thereby ensuring improved welding.

A water passing component, a laser welding device and a welding method thereof are presented. The water passing component comprises a hose and a hose joint, the hose joint and the hose matched and connected to form a connecting and matching position. The connecting and matching position can be melted under laser beams to weld the hose and the hose joint into a whole; the width of a gap of a weld matching surface corresponding to the connecting and matching position is less than 0.075 mm. The present invention melts the connecting and matching position using the laser welding technology to weld the hose and the hose joint into a whole. The transparency of the hose and the hose joint is not limited, and there is no requirement for the transparency of the hose and the hose joint, thereby reducing production cost, increasing production efficiency and expanding use.

The invention relates to a plastic pipeline (1), having at least one radial branch. The invention is based on the object of providing a plastic pipeline (1) having a radial branch (4, 5) that avoids the problems of the known configurations. This object is achieved by the plastic pipeline (1) having in the intended region of the branching a bore (2) and a saddle-shaped plastic element (4, 5) with a through-bore (6), the through-bore (6) of the saddle-shaped plastic element (4, 5) being in line with the bore (2) in the plastic pipeline (1) and the saddle-shaped plastic element (4, 5) being formed from a plastics material that can be fused with the material of the plastic pipeline (1), and the saddle-shaped plastic element (4, 5) being connected to the plastic pipeline (1) in a pressure- and fluid-tight manner.
