Abstract

Security marking system for multilayer composite pipes consisting of an outer pipe (1), an inner pipe (2), a metallic oxygen barrier layer (3) and two bonding agent layers (4) comprises a concealed pipe marking (5) provided on the metallic oxygen barrier layer located between the bonding agent layers. Independent claims are also included for alternative security marking systems.

Description

State of the art

Generally it is known that multi-layer composite pipes, which are from production certified companies and in the artisan sanitary and heating sector are used on the outside in accordance with the guidelines Have identification marks.

This Type of marking, which is usually done using a laser printer, is not up to the rough construction site requirements and is therefore often beyond recognition when used smudges or is also completely by means of conventional cleaning agents removable, so that a unique manufacturer identification in the Damage or repair is no longer given.

As a result the said Disadvantages will also be the use of suppliers Liability for material defects for the Construction work difficult or impossible.

A Another negative consequence of conventional pipe labeling is the possibility their easy imitation, so that in the context of globalization increasingly foreign Pipe suppliers with pipe plagiarism falsify the market, which in particular the Interests of the original manufacturer as well as the executing company Construction to a high degree opposes.

problem

The The invention specified in claim 1 is based on the problem a technical solution principle to offer that a durable and largely forgery-proof Labeling of multilayer pipes guaranteed.

solution

According to the invention Problem solved by the features specified in the protection claims.

Achieved advantages

The Invention is designed so that with relatively little effort and simple technical means a damage-proof and therefore permanent Identification of multi-layer composite pipes is given and thus Guarantees a non-manipulable manufacturer specification if necessary.

In order to is crucial to both the security needs of the other construction Installation trade as well as the manufacturing companies by now clear assignability of the tube goods is taken into account.

The In terms of labeling method, invention also brings the Additional advantage that the pipe labeling is now, for example also by means of embossing processes, Burn-in process and the like can be done.

embodiment

The The invention will be explained in more detail below using three exemplary embodiments.

It demonstrate:

1 a five-layer composite pipe

2 a three-layer composite pipe

3 a two-layer composite pipe.

This in 1 The multi-layer composite pipe shown consists essentially of an outer pipe made of plastic ( 1 ), an inner tube also made of plastic ( 2 ), a suitable metallic oxygen barrier layer ( 3 ), for example in the form of welded aluminum foil and two suitable adhesive layers ( 4 ), the pipe identification ( 5 ) on the metallic oxygen barrier layer ( 3 ) is arranged in a suitable manner.

2 shows a multi-layer composite pipe, consisting essentially of the outer pipe ( 1 ), the inner tube ( 2 ) and the metallic oxygen barrier layer ( 3 ) on which the identification-reliable pipe identification ( 5 ) is located.

According to 3 the multi-layer composite pipe consists of the outer pipe ( 1 ) and an inner tube ( 2 ) made of corrosion-resistant metal, on which the pipe identification ( 5 ) is invisible.

The arrangement of the pipe marking according to the invention ( 5 ) according to the 1 . 2 and 3 takes place in a variable manner on the circumference of the tube layer to be marked, along its axis, spirally around the same or endlessly.

The The principle of the invention is a so-called Secure marking, which if necessary by simply peeling off the each above Making pipe layers visible is therefore a distinctive one Manufacturer identification guaranteed.

The conventional labeling solution can be according to the new invention order can be applied in parallel without any problems.

Claims (3)

Safety marking system for multi-layer composite pipes, consisting of an outer pipe ( 1 ), an inner tube ( 2 ), a metallic oxygen barrier layer ( 3 ) and two layers of bonding agent ( 4 ) characterized in that the between the adhesion promoter layers ( 4 ) located metallic oxygen barrier layer ( 3 ) with the hidden pipe marking ( 5 ) is equipped. Safety marking system for multi-layer composite pipes which have an outer pipe ( 1 ), an inner tube ( 2 ) and a metallic oxygen barrier layer ( 3 ), characterized in that on the between the outer tube ( 1 ) and the inner tube ( 2 ) metallic oxygen barrier layer ( 3 ) the pipe marking ( 5 ) is provided hidden. Safety marking system for multi-layer composite pipes consisting of an outer pipe ( 1 ) and an inner tube ( 2 ), characterized in that the pipe marking on the inner pipe ( 2 ) is concealed.
