A method and device for the ultrasonic testing of a weld of an electric arc-welded sleeve () for plastic pipes (), having the following steps:

Testing sleeve welding

A method for inspecting a weld of plastic pipes by means of a data processing device, comprising:

Method for inspecting a weld

Weld seam testing chain for testing a weld seam by means of ultrasound on two plastic tubes welded together at the ends, comprising standard chain links, wherein the standard chain links are hooked together to form the weld seam testing chain, and the chain can be lengthened or shortened individually, a sensor receptacle for accommodating the ultrasonic sensor, and an adjusting unit for the fine adjustment of the weld seam testing chain length, wherein the standard chain links have a hook on one side and a hook receptacle on the opposite side, thereby enabling the individual chain links to be hooked together.

Weld seam testing chain

Electric welding coupler for the welding of pipes made of thermoplastic material or other weldable plastics comprising a cylindrical body made of thermoplastic material or other weldable plastics, containing at least one welding element, wherein the welding element is arranged close to the inner diameter of the cylindrical body, wherein the welding element forms at least two welding zones, a contact for feeding the electric current and at least one cavity, wherein the cavity is arranged in the cylindrical body, wherein a reinforcing ring is arranged around the outer circumference respectively outer diameter of the cylindrical body.

Chamber coupler

A fitting () of weldable, thermoplastic material of a modular structure, comprising a number of elements (), at least one main element () and at least one connecting element (), characterized in that the elements () have end faces () at right angles to the center axis (), and the elements () are welded to one another exclusively at the end faces ().

Modular fitting

A method and a device for welding plastic pipes () made of thermoplastic material by a butt-welding method, wherein the pipes () are held in a coaxial position in relation to one another by clamping points (), are trimmed by a trimmer (), which can be brought between the clamping points (), and are heated up by heated tools (), which can be fitted in place of the trimmer (), wherein the heating of the free pipe ends () to be welded has the effect of forming a melting region which forms a bead when pressing occurs, the pipe projection () of the pipes () being trimmed to a defined size.

Method and device for the butt-welding of pipes made of thermoplastic material

A saddle, in particular a clamping saddle for plastic pipes, containing a branch projection, a saddle piece, center axes (X), (Y) and (Z), and a groove for the arrangement of a seal, wherein the inner cheek of the groove is arranged, throughout the course of the groove, perpendicular to the inner surface of the saddle piece.

Saddle for a branch connection

In one embodiment, a method of filling a container with a liquid drug from a drug reservoir may include: a) connecting a container and a drug reservoir with a cannula such that the drug reservoir and the container fluidically communicate with each other via the cannula, while being hermetically sealed; b) reducing a first volume contained within the container to displace a gaseous medium from the first volume of the container via the cannula into a second volume contained within the drug reservoir; c) increasing the first volume of the container to displace the liquid drug from the second volume of the drug reservoir into the first volume of the container to fill the container; and d) disconnecting the container and the drug reservoir. Before performing action d), action b) and action c) can be successively performed more than once to stepwise increase an amount of liquid drug displaced.
