Problems solved by technology

The disclosed design has the disadvantage that the outer diameter of the socket significantly exceeds the outer diameter of the pipe part, since the respective common pipe part is also used as a socket

Embodiment Construction

[0013] Referring to Figure 1, a continuously manufactured double walled pipe is formed as an extruded length of pipe consisting essentially of the actual pipe parts 1,2. They generally consist of a smooth-walled cylindrical inner tube 3 and a corrugated outer tube 4 . The outer tube 4 has approximately trapezoidal elevations 5 , a groove 8 formed between the side walls 6 , 7 of two adjacent elevations 5 . At the bottom 9 of the groove 8 the outer tube 4 and the inner tube 3 are welded together. Double wall pipes of this type and construction are well known and widely used in practice.

[0014] A socket 10 adjacent to the pipe part 1 is formed between the two pipe parts 1 , 2 . Near the bottom 11 of the socket, ie behind the flared portion 12 of the tube part 1, the socket 10 has a short, smooth-walled cylindrical portion 13. Like the expanded portion 12, the smooth walled portion 13 is primarily a single walled structure rather than a double walled structure. The smooth-wa...

Abstract

A pipe construction kit comprises two pipe sections in the form of twin-wall pipes. A spigot is formed on one end of a pipe section, while a socket is formed on the associated end of the other pipe section. The socket and the spigot are twin-wall pipes, having predominantly smooth-walled internal pipe sections and corrugated external pipe sections with elevations and troughs. The outside diameter of the pipe sections and the outside diameter of the socket are approximately equal.

Description

technical field [0001] The invention relates to a tubular structural element. Background technique [0002] US Patent 5,071,173 discloses a general type of tubular structural element. The disclosed design includes a smooth-walled socket whose outer diameter does not protrude above the raised outer diameter of the pipe member. Thus, the disclosed design enables this type of pipe construction element to be used in the repair of drain pipes, since the continuously connected pipe parts have a consistent maximum outer diameter. Likewise, this design of the socket has the advantage that a pipe part having a socket at one end and a socket at the other end can be transported without risking damage to the socket. If the socket also has an outer diameter corresponding to the outer diameter of the pipe part (this is prior art), and if, therefore, the socket has an inner diameter at least corresponding to the outer diameter of the pipe part, then there will be problems during transpor...
