Problems solved by technology

[0010] The disadvantage of this invention is that, for such a connection, two compensating elements with two welding zones each and a sleeve that applies pressure to the welding points are required
Especially in the case of large diameters, resulting in high material costs as well as high assembly costs

Embodiment Construction

[0035] figure 1 An electric welding socket 1 for connecting plastic pipes is shown. The sleeve body 2 is made of weldable plastic, preferably thermoplastic material. The electric welding socket 1 has at least two heating zones 3 which are connected to an electric current through contacts 6 in order to heat the heating zones 3 to weld the pipe to the electric welding socket 1 .

[0036] figure 1The electric welding socket 1 depicted in has a groove 4 extending across the entire length L of the socket body 2 . Owing to the groove 4 , the ring stiffness of the welding sleeve 1 is deliberately weakened, so that the sleeve 1 expands during the welding process with the volume of the plastic to be welded. During the cooling of the welded joint, the volume of the plastic of the welded seam decreases. By virtue of the flexibility of the sleeve body 2 , the size or diameter of the sleeve body 2 is likewise reduced due to the incorporated groove 4 . The formation of air bubbles can ...

Abstract

Electric welding sleeve having a cylindrical sleeve body for the welding of pipes made of thermoplastic material or other weldable plastics, containing at least two heating zones having respectively a plurality of electrically conductive windings and contacts for the supply of the electric current, wherein at least one longitudinally running groove is arranged along the outer surface of the cylindrical sleeve body.

Description

technical field [0001] The invention relates to an electric welding socket with a cylindrical socket body for welding pipes made of thermoplastic material or other weldable plastics, comprising at least two heating zones each having a plurality of Conductive coils and contacts. Background technique [0002] Mainly in recent years, for reasons of weight and corrosion, pipes made of thermoplastic materials have been increasingly used in pipeline construction, more specifically for gas and water supply and for conveying air, waste water or other Construction of pipeline networks for chemicals. The pipes used are usually made of pressure-resistant plastic. For reasons of quality and efficiency, electric welding sockets are often used to join such pipes. The larger the pipe diameter of the pipes to be connected, the more effort is required to connect the individual pipe parts. Due to the relatively large gap between the pipe and the welding sleeve in the case of large pipe cr...
